+\chapter{Introduction}
+\section{What is LibTomMath?}
+LibTomMath is a library of source code which provides a series of efficient and carefully written functions for manipulating
+large integer numbers.  It was written in portable ISO C source code so that it will build on any platform with a conforming
+C compiler.  
+
+In a nutshell the library was written from scratch with verbose comments to help instruct computer science students how
+to implement ``bignum'' math.  However, the resulting code has proven to be very useful.  It has been used by numerous 
+universities, commercial and open source software developers.  It has been used on a variety of platforms ranging from
+Linux and Windows based x86 to ARM based Gameboys and PPC based MacOS machines.  
+
+\section{License}
+As of the v0.25 the library source code has been placed in the public domain with every new release.  As of the v0.28
+release the textbook ``Implementing Multiple Precision Arithmetic'' has been placed in the public domain with every new
+release as well.  This textbook is meant to compliment the project by providing a more solid walkthrough of the development
+algorithms used in the library.
+
+Since both\footnote{Note that the MPI files under mtest/ are copyrighted by Michael Fromberger.  They are not required to use LibTomMath.} are in the 
+public domain everyone is entitled to do with them as they see fit.
+
+\section{Building LibTomMath}
+
+LibTomMath is meant to be very ``GCC friendly'' as it comes with a makefile well suited for GCC.  However, the library will
+also build in MSVC, Borland C out of the box.  For any other ISO C compiler a makefile will have to be made by the end
+developer.  
+
+\subsection{Static Libraries}
+To build as a static library for GCC issue the following
+\begin{alltt}
+make
+\end{alltt}
+
+command.  This will build the library and archive the object files in ``libtommath.a''.  Now you link against 
+that and include ``tommath.h'' within your programs.  Alternatively to build with MSVC issue the following
+\begin{alltt}
+nmake -f makefile.msvc
+\end{alltt}
+
+This will build the library and archive the object files in ``tommath.lib''.  This has been tested with MSVC 
+version 6.00 with service pack 5.  
+
+\subsection{Shared Libraries}
+To build as a shared library for GCC issue the following
+\begin{alltt}
+make -f makefile.shared
+\end{alltt}
+This requires the ``libtool'' package (common on most Linux/BSD systems).  It will build LibTomMath as both shared
+and static then install (by default) into /usr/lib as well as install the header files in /usr/include.  The shared 
+library (resource) will be called ``libtommath.la'' while the static library called ``libtommath.a''.  Generally 
+you use libtool to link your application against the shared object.  
+
+There is limited support for making a ``DLL'' in windows via the ``makefile.cygwin\_dll'' makefile.  It requires 
+Cygwin to work with since it requires the auto-export/import functionality.  The resulting DLL and import library 
+``libtommath.dll.a'' can be used to link LibTomMath dynamically to any Windows program using Cygwin.
+
+\subsection{Testing}
+To build the library and the test harness type
+
+\begin{alltt}
+make test
+\end{alltt}
+
+This will build the library, ``test'' and ``mtest/mtest''.  The ``test'' program will accept test vectors and verify the
+results.  ``mtest/mtest'' will generate test vectors using the MPI library by Michael Fromberger\footnote{A copy of MPI
+is included in the package}.  Simply pipe mtest into test using
+
+\begin{alltt}
+mtest/mtest | test
+\end{alltt}
+
+If you do not have a ``/dev/urandom'' style RNG source you will have to write your own PRNG and simply pipe that into 
+mtest.  For example, if your PRNG program is called ``myprng'' simply invoke
+
+\begin{alltt}
+myprng | mtest/mtest | test
+\end{alltt}
+
+This will output a row of numbers that are increasing.  Each column is a different test (such as addition, multiplication, etc)
+that is being performed.  The numbers represent how many times the test was invoked.  If an error is detected the program
+will exit with a dump of the relevent numbers it was working with.
+
+\section{Build Configuration}
+LibTomMath can configured at build time in three phases we shall call ``depends'', ``tweaks'' and ``trims''.  
+Each phase changes how the library is built and they are applied one after another respectively.  
+
+To make the system more powerful you can tweak the build process.  Classes are defined in the file
+``tommath\_superclass.h''.  By default, the symbol ``LTM\_ALL'' shall be defined which simply 
+instructs the system to build all of the functions.  This is how LibTomMath used to be packaged.  This will give you 
+access to every function LibTomMath offers.
+
+However, there are cases where such a build is not optional.  For instance, you want to perform RSA operations.  You 
+don't need the vast majority of the library to perform these operations.  Aside from LTM\_ALL there is 
+another pre--defined class ``SC\_RSA\_1'' which works in conjunction with the RSA from LibTomCrypt.  Additional 
+classes can be defined base on the need of the user.
+
+\subsection{Build Depends}
+In the file tommath\_class.h you will see a large list of C ``defines'' followed by a series of ``ifdefs''
+which further define symbols.  All of the symbols (technically they're macros $\ldots$) represent a given C source
+file.  For instance, BN\_MP\_ADD\_C represents the file ``bn\_mp\_add.c''.  When a define has been enabled the
+function in the respective file will be compiled and linked into the library.  Accordingly when the define
+is absent the file will not be compiled and not contribute any size to the library.
+
+You will also note that the header tommath\_class.h is actually recursively included (it includes itself twice).  
+This is to help resolve as many dependencies as possible.  In the last pass the symbol LTM\_LAST will be defined.  
+This is useful for ``trims''.
+
+\subsection{Build Tweaks}
+A tweak is an algorithm ``alternative''.  For example, to provide tradeoffs (usually between size and space).
+They can be enabled at any pass of the configuration phase.
+

+\hline \textbf{Define} & \textbf{Purpose} \\
+\hline BN\_MP\_DIV\_SMALL & Enables a slower, smaller and equally \\
+                          & functional mp\_div() function \\
+\hline
+\end{tabular}
+\end{center}
+\end{small}
+
+\subsection{Build Trims}
+A trim is a manner of removing functionality from a function that is not required.  For instance, to perform
+RSA cryptography you only require exponentiation with odd moduli so even moduli support can be safely removed.  
+Build trims are meant to be defined on the last pass of the configuration which means they are to be defined
+only if LTM\_LAST has been defined.

+\section{Purpose of LibTomMath}
+Unlike  GNU MP (GMP) Library, LIP, OpenSSL or various other commercial kits (Miracl), LibTomMath was not written with 
+bleeding edge performance in mind.  First and foremost LibTomMath was written to be entirely open.  Not only is the 
+source code public domain (unlike various other GPL/etc licensed code), not only is the code freely downloadable but the
+source code is also accessible for computer science students attempting to learn ``BigNum'' or multiple precision
+arithmetic techniques. 
+
+LibTomMath was written to be an instructive collection of source code.  This is why there are many comments, only one
+function per source file and often I use a ``middle-road'' approach where I don't cut corners for an extra 2\% speed
+increase.
+
+Source code alone cannot really teach how the algorithms work which is why I also wrote a textbook that accompanies
+the library (beat that!).
+
+So you may be thinking ``should I use LibTomMath?'' and the answer is a definite maybe.  Let me tabulate what I think
+are the pros and cons of LibTomMath by comparing it to the math routines from GnuPG\footnote{GnuPG v1.2.3 versus LibTomMath v0.28}.
+
+\newpage\begin{figure}[here]
+\begin{small}
+\begin{center}
+\begin{tabular}{|l|c|c|l|}
+\hline \textbf{Criteria} & \textbf{Pro} & \textbf{Con} & \textbf{Notes} \\
+\hline Few lines of code per file & X & & GnuPG $ = 300.9$, LibTomMath  $ = 76.04$ \\
+\hline Commented function prototypes & X && GnuPG function names are cryptic. \\
+\hline Speed && X & LibTomMath is slower.  \\
+\hline Totally free & X & & GPL has unfavourable restrictions.\\
+\hline Large function base & X & & GnuPG is barebones. \\
+\hline Four modular reduction algorithms & X & & Faster modular exponentiation. \\
+\hline Portable & X & & GnuPG requires configuration to build. \\
+\hline
+\end{tabular}
+\end{center}
+\end{small}
+\caption{LibTomMath Valuation}
+\end{figure}
+
+It may seem odd to compare LibTomMath to GnuPG since the math in GnuPG is only a small portion of the entire application. 
+However, LibTomMath was written with cryptography in mind.  It provides essentially all of the functions a cryptosystem
+would require when working with large integers.  
+
+So it may feel tempting to just rip the math code out of GnuPG (or GnuMP where it was taken from originally) in your
+own application but I think there are reasons not to.  While LibTomMath is slower than libraries such as GnuMP it is
+not normally significantly slower.  On x86 machines the difference is normally a factor of two when performing modular
+exponentiations.
+
+Essentially the only time you wouldn't use LibTomMath is when blazing speed is the primary concern.
+
+\chapter{Getting Started with LibTomMath}
+\section{Building Programs}
+In order to use LibTomMath you must include ``tommath.h'' and link against the appropriate library file (typically 
+libtommath.a).  There is no library initialization required and the entire library is thread safe.
+
+\section{Return Codes}
+There are three possible return codes a function may return.
+
+\index{MP\_OKAY}\index{MP\_YES}\index{MP\_NO}\index{MP\_VAL}\index{MP\_MEM}
+\begin{figure}[here!]
+\begin{center}
+\begin{small}
+\begin{tabular}{|l|l|}
+\hline \textbf{Code} & \textbf{Meaning} \\
+\hline MP\_OKAY & The function succeeded. \\
+\hline MP\_VAL  & The function input was invalid. \\
+\hline MP\_MEM  & Heap memory exhausted. \\
+\hline &\\
+\hline MP\_YES  & Response is yes. \\
+\hline MP\_NO   & Response is no. \\
+\hline
+\end{tabular}
+\end{small}
+\end{center}
+\caption{Return Codes}
+\end{figure}
+
+The last two codes listed are not actually ``return'ed'' by a function.  They are placed in an integer (the caller must
+provide the address of an integer it can store to) which the caller can access.  To convert one of the three return codes
+to a string use the following function.
+
+\index{mp\_error\_to\_string}
+\begin{alltt}
+char *mp_error_to_string(int code);
+\end{alltt}
+
+This will return a pointer to a string which describes the given error code.  It will not work for the return codes 
+MP\_YES and MP\_NO.  
+
+\section{Data Types}
+The basic ``multiple precision integer'' type is known as the ``mp\_int'' within LibTomMath.  This data type is used to
+organize all of the data required to manipulate the integer it represents.  Within LibTomMath it has been prototyped
+as the following.
+
+\index{mp\_int}
+\begin{alltt}
+typedef struct  \{
+    int used, alloc, sign;
+    mp_digit *dp;
+\} mp_int;
+\end{alltt}
+
+Where ``mp\_digit'' is a data type that represents individual digits of the integer.  By default, an mp\_digit is the
+ISO C ``unsigned long'' data type and each digit is $28-$bits long.  The mp\_digit type can be configured to suit other
+platforms by defining the appropriate macros.  
+
+All LTM functions that use the mp\_int type will expect a pointer to mp\_int structure.  You must allocate memory to
+hold the structure itself by yourself (whether off stack or heap it doesn't matter).  The very first thing that must be
+done to use an mp\_int is that it must be initialized.
+
+\section{Function Organization}
+
+The arithmetic functions of the library are all organized to have the same style prototype.  That is source operands
+are passed on the left and the destination is on the right.  For instance,
+
+\begin{alltt}
+mp_add(&a, &b, &c);       /* c = a + b */
+mp_mul(&a, &a, &c);       /* c = a * a */
+mp_div(&a, &b, &c, &d);   /* c = [a/b], d = a mod b */
+\end{alltt}
+
+Another feature of the way the functions have been implemented is that source operands can be destination operands as well.
+For instance,
+
+\begin{alltt}
+mp_add(&a, &b, &b);       /* b = a + b */
+mp_div(&a, &b, &a, &c);   /* a = [a/b], c = a mod b */
+\end{alltt}
+
+This allows operands to be re-used which can make programming simpler.
+
+\section{Initialization}
+\subsection{Single Initialization}
+A single mp\_int can be initialized with the ``mp\_init'' function. 
+
+\index{mp\_init}
+\begin{alltt}
+int mp_init (mp_int * a);
+\end{alltt}
+
+This function expects a pointer to an mp\_int structure and will initialize the members of the structure so the mp\_int
+represents the default integer which is zero.  If the functions returns MP\_OKAY then the mp\_int is ready to be used
+by the other LibTomMath functions.
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+   mp_int number;
+   int result;
+
+   if ((result = mp_init(&number)) != MP_OKAY) \{
+      printf("Error initializing the number.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+ 
+   /* use the number */
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+\subsection{Single Free}
+When you are finished with an mp\_int it is ideal to return the heap it used back to the system.  The following function 
+provides this functionality.
+
+\index{mp\_clear}
+\begin{alltt}
+void mp_clear (mp_int * a);
+\end{alltt}
+
+The function expects a pointer to a previously initialized mp\_int structure and frees the heap it uses.  It sets the 
+pointer\footnote{The ``dp'' member.} within the mp\_int to \textbf{NULL} which is used to prevent double free situations. 
+Is is legal to call mp\_clear() twice on the same mp\_int in a row.  
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+   mp_int number;
+   int result;
+
+   if ((result = mp_init(&number)) != MP_OKAY) \{
+      printf("Error initializing the number.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+ 
+   /* use the number */
+
+   /* We're done with it. */
+   mp_clear(&number);
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+\subsection{Multiple Initializations}
+Certain algorithms require more than one large integer.  In these instances it is ideal to initialize all of the mp\_int
+variables in an ``all or nothing'' fashion.  That is, they are either all initialized successfully or they are all
+not initialized.
+
+The  mp\_init\_multi() function provides this functionality.
+
+\index{mp\_init\_multi} \index{mp\_clear\_multi}
+\begin{alltt}
+int mp_init_multi(mp_int *mp, ...);
+\end{alltt}
+
+It accepts a \textbf{NULL} terminated list of pointers to mp\_int structures.  It will attempt to initialize them all
+at once.  If the function returns MP\_OKAY then all of the mp\_int variables are ready to use, otherwise none of them
+are available for use.  A complementary mp\_clear\_multi() function allows multiple mp\_int variables to be free'd 
+from the heap at the same time.  
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+   mp_int num1, num2, num3;
+   int result;
+
+   if ((result = mp_init_multi(&num1, 
+                               &num2,
+                               &num3, NULL)) != MP\_OKAY) \{      
+      printf("Error initializing the numbers.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+ 
+   /* use the numbers */
+
+   /* We're done with them. */
+   mp_clear_multi(&num1, &num2, &num3, NULL);
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+\subsection{Other Initializers}
+To initialized and make a copy of an mp\_int the mp\_init\_copy() function has been provided.  
+
+\index{mp\_init\_copy}
+\begin{alltt}
+int mp_init_copy (mp_int * a, mp_int * b);
+\end{alltt}
+
+This function will initialize $a$ and make it a copy of $b$ if all goes well.
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+   mp_int num1, num2;
+   int result;
+
+   /* initialize and do work on num1 ... */
+
+   /* We want a copy of num1 in num2 now */
+   if ((result = mp_init_copy(&num2, &num1)) != MP_OKAY) \{
+     printf("Error initializing the copy.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+ 
+   /* now num2 is ready and contains a copy of num1 */
+
+   /* We're done with them. */
+   mp_clear_multi(&num1, &num2, NULL);
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+Another less common initializer is mp\_init\_size() which allows the user to initialize an mp\_int with a given
+default number of digits.  By default, all initializers allocate \textbf{MP\_PREC} digits.  This function lets
+you override this behaviour.
+
+\index{mp\_init\_size}
+\begin{alltt}
+int mp_init_size (mp_int * a, int size);
+\end{alltt}
+
+The $size$ parameter must be greater than zero.  If the function succeeds the mp\_int $a$ will be initialized
+to have $size$ digits (which are all initially zero).  
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+   mp_int number;
+   int result;
+
+   /* we need a 60-digit number */
+   if ((result = mp_init_size(&number, 60)) != MP_OKAY) \{
+      printf("Error initializing the number.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+ 
+   /* use the number */
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+\section{Maintenance Functions}
+
+\subsection{Reducing Memory Usage}
+When an mp\_int is in a state where it won't be changed again\footnote{A Diffie-Hellman modulus for instance.} excess
+digits can be removed to return memory to the heap with the mp\_shrink() function.
+
+\index{mp\_shrink}
+\begin{alltt}
+int mp_shrink (mp_int * a);
+\end{alltt}
+
+This will remove excess digits of the mp\_int $a$.  If the operation fails the mp\_int should be intact without the
+excess digits being removed.  Note that you can use a shrunk mp\_int in further computations, however, such operations
+will require heap operations which can be slow.  It is not ideal to shrink mp\_int variables that you will further
+modify in the system (unless you are seriously low on memory).  
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+   mp_int number;
+   int result;
+
+   if ((result = mp_init(&number)) != MP_OKAY) \{
+      printf("Error initializing the number.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+ 
+   /* use the number [e.g. pre-computation]  */
+
+   /* We're done with it for now. */
+   if ((result = mp_shrink(&number)) != MP_OKAY) \{
+      printf("Error shrinking the number.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+   /* use it .... */
+
+
+   /* we're done with it. */ 
+   mp_clear(&number);
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+\subsection{Adding additional digits}
+
+Within the mp\_int structure are two parameters which control the limitations of the array of digits that represent
+the integer the mp\_int is meant to equal.   The \textit{used} parameter dictates how many digits are significant, that is,
+contribute to the value of the mp\_int.  The \textit{alloc} parameter dictates how many digits are currently available in
+the array.  If you need to perform an operation that requires more digits you will have to mp\_grow() the mp\_int to
+your desired size.  
+
+\index{mp\_grow}
+\begin{alltt}
+int mp_grow (mp_int * a, int size);
+\end{alltt}
+
+This will grow the array of digits of $a$ to $size$.  If the \textit{alloc} parameter is already bigger than
+$size$ the function will not do anything.
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+   mp_int number;
+   int result;
+
+   if ((result = mp_init(&number)) != MP_OKAY) \{
+      printf("Error initializing the number.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+ 
+   /* use the number */
+
+   /* We need to add 20 digits to the number  */
+   if ((result = mp_grow(&number, number.alloc + 20)) != MP_OKAY) \{
+      printf("Error growing the number.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+
+   /* use the number */
+
+   /* we're done with it. */ 
+   mp_clear(&number);
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+\chapter{Basic Operations}
+\section{Small Constants}
+Setting mp\_ints to small constants is a relatively common operation.  To accomodate these instances there are two
+small constant assignment functions.  The first function is used to set a single digit constant while the second sets
+an ISO C style ``unsigned long'' constant.  The reason for both functions is efficiency.  Setting a single digit is quick but the
+domain of a digit can change (it's always at least $0 \ldots 127$).  
+
+\subsection{Single Digit}
+
+Setting a single digit can be accomplished with the following function.
+
+\index{mp\_set}
+\begin{alltt}
+void mp_set (mp_int * a, mp_digit b);
+\end{alltt}
+
+This will zero the contents of $a$ and make it represent an integer equal to the value of $b$.  Note that this
+function has a return type of \textbf{void}.  It cannot cause an error so it is safe to assume the function
+succeeded.
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+   mp_int number;
+   int result;
+
+   if ((result = mp_init(&number)) != MP_OKAY) \{
+      printf("Error initializing the number.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+ 
+   /* set the number to 5 */
+   mp_set(&number, 5);
+
+   /* we're done with it. */ 
+   mp_clear(&number);
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+\subsection{Long Constants}
+
+To set a constant that is the size of an ISO C ``unsigned long'' and larger than a single digit the following function 
+can be used.
+
+\index{mp\_set\_int}
+\begin{alltt}
+int mp_set_int (mp_int * a, unsigned long b);
+\end{alltt}
+
+This will assign the value of the 32-bit variable $b$ to the mp\_int $a$.  Unlike mp\_set() this function will always
+accept a 32-bit input regardless of the size of a single digit.  However, since the value may span several digits 
+this function can fail if it runs out of heap memory.
+
+To get the ``unsigned long'' copy of an mp\_int the following function can be used.
+
+\index{mp\_get\_int}
+\begin{alltt}
+unsigned long mp_get_int (mp_int * a);
+\end{alltt}
+
+This will return the 32 least significant bits of the mp\_int $a$.  
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+   mp_int number;
+   int result;
+
+   if ((result = mp_init(&number)) != MP_OKAY) \{
+      printf("Error initializing the number.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+ 
+   /* set the number to 654321 (note this is bigger than 127) */
+   if ((result = mp_set_int(&number, 654321)) != MP_OKAY) \{
+      printf("Error setting the value of the number.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+   printf("number == \%lu", mp_get_int(&number));
+
+   /* we're done with it. */ 
+   mp_clear(&number);
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+This should output the following if the program succeeds.
+
+\begin{alltt}
+number == 654321
+\end{alltt}
+
+\subsection{Initialize and Setting Constants}
+To both initialize and set small constants the following two functions are available.
+\index{mp\_init\_set} \index{mp\_init\_set\_int}
+\begin{alltt}
+int mp_init_set (mp_int * a, mp_digit b);
+int mp_init_set_int (mp_int * a, unsigned long b);
+\end{alltt}
+
+Both functions work like the previous counterparts except they first mp\_init $a$ before setting the values.  
+
+\begin{alltt}
+int main(void)
+\{
+   mp_int number1, number2;
+   int    result;
+
+   /* initialize and set a single digit */
+   if ((result = mp_init_set(&number1, 100)) != MP_OKAY) \{
+      printf("Error setting number1: \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}             
+
+   /* initialize and set a long */
+   if ((result = mp_init_set_int(&number2, 1023)) != MP_OKAY) \{
+      printf("Error setting number2: \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+   /* display */
+   printf("Number1, Number2 == \%lu, \%lu",
+          mp_get_int(&number1), mp_get_int(&number2));
+
+   /* clear */
+   mp_clear_multi(&number1, &number2, NULL);
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt}
+
+If this program succeeds it shall output.
+\begin{alltt}
+Number1, Number2 == 100, 1023
+\end{alltt}
+
+\section{Comparisons}
+
+Comparisons in LibTomMath are always performed in a ``left to right'' fashion.  There are three possible return codes
+for any comparison.
+
+\index{MP\_GT} \index{MP\_EQ} \index{MP\_LT}
+\begin{figure}[here]
+\begin{center}
+\begin{tabular}{|c|c|}
+\hline \textbf{Result Code} & \textbf{Meaning} \\
+\hline MP\_GT & $a > b$ \\
+\hline MP\_EQ & $a = b$ \\
+\hline MP\_LT & $a < b$ \\
+\hline
+\end{tabular}
+\end{center}
+\caption{Comparison Codes for $a, b$}
+\label{fig:CMP}
+\end{figure}
+
+In figure \ref{fig:CMP} two integers $a$ and $b$ are being compared.  In this case $a$ is said to be ``to the left'' of 
+$b$.  
+
+\subsection{Unsigned comparison}
+
+An unsigned comparison considers only the digits themselves and not the associated \textit{sign} flag of the 
+mp\_int structures.  This is analogous to an absolute comparison.  The function mp\_cmp\_mag() will compare two
+mp\_int variables based on their digits only. 
+
+\index{mp\_cmp\_mag}
+\begin{alltt}
+int mp_cmp(mp_int * a, mp_int * b);
+\end{alltt}
+This will compare $a$ to $b$ placing $a$ to the left of $b$.  This function cannot fail and will return one of the
+three compare codes listed in figure \ref{fig:CMP}.
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+   mp_int number1, number2;
+   int result;
+
+   if ((result = mp_init_multi(&number1, &number2, NULL)) != MP_OKAY) \{
+      printf("Error initializing the numbers.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+ 
+   /* set the number1 to 5 */
+   mp_set(&number1, 5);
+  
+   /* set the number2 to -6 */
+   mp_set(&number2, 6);
+   if ((result = mp_neg(&number2, &number2)) != MP_OKAY) \{
+      printf("Error negating number2.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+   switch(mp_cmp_mag(&number1, &number2)) \{
+       case MP_GT:  printf("|number1| > |number2|"); break;
+       case MP_EQ:  printf("|number1| = |number2|"); break;
+       case MP_LT:  printf("|number1| < |number2|"); break;
+   \}
+
+   /* we're done with it. */ 
+   mp_clear_multi(&number1, &number2, NULL);
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+If this program\footnote{This function uses the mp\_neg() function which is discussed in section \ref{sec:NEG}.} completes 
+successfully it should print the following.
+
+\begin{alltt}
+|number1| < |number2|
+\end{alltt}
+
+This is because $\vert -6 \vert = 6$ and obviously $5 < 6$.
+
+\subsection{Signed comparison}
+
+To compare two mp\_int variables based on their signed value the mp\_cmp() function is provided.
+
+\index{mp\_cmp}
+\begin{alltt}
+int mp_cmp(mp_int * a, mp_int * b);
+\end{alltt}
+
+This will compare $a$ to the left of $b$.  It will first compare the signs of the two mp\_int variables.  If they
+differ it will return immediately based on their signs.  If the signs are equal then it will compare the digits
+individually.  This function will return one of the compare conditions codes listed in figure \ref{fig:CMP}.
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+   mp_int number1, number2;
+   int result;
+
+   if ((result = mp_init_multi(&number1, &number2, NULL)) != MP_OKAY) \{
+      printf("Error initializing the numbers.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+ 
+   /* set the number1 to 5 */
+   mp_set(&number1, 5);
+  
+   /* set the number2 to -6 */
+   mp_set(&number2, 6);
+   if ((result = mp_neg(&number2, &number2)) != MP_OKAY) \{
+      printf("Error negating number2.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+   switch(mp_cmp(&number1, &number2)) \{
+       case MP_GT:  printf("number1 > number2"); break;
+       case MP_EQ:  printf("number1 = number2"); break;
+       case MP_LT:  printf("number1 < number2"); break;
+   \}
+
+   /* we're done with it. */ 
+   mp_clear_multi(&number1, &number2, NULL);
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+If this program\footnote{This function uses the mp\_neg() function which is discussed in section \ref{sec:NEG}.} completes 
+successfully it should print the following.
+
+\begin{alltt}
+number1 > number2
+\end{alltt}
+
+\subsection{Single Digit}
+
+To compare a single digit against an mp\_int the following function has been provided.
+
+\index{mp\_cmp\_d}
+\begin{alltt}
+int mp_cmp_d(mp_int * a, mp_digit b);
+\end{alltt}
+
+This will compare $a$ to the left of $b$ using a signed comparison.  Note that it will always treat $b$ as 
+positive.  This function is rather handy when you have to compare against small values such as $1$ (which often
+comes up in cryptography).  The function cannot fail and will return one of the tree compare condition codes
+listed in figure \ref{fig:CMP}.
+
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+   mp_int number;
+   int result;
+
+   if ((result = mp_init(&number)) != MP_OKAY) \{
+      printf("Error initializing the number.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+ 
+   /* set the number to 5 */
+   mp_set(&number, 5);
+
+   switch(mp_cmp_d(&number, 7)) \{
+       case MP_GT:  printf("number > 7"); break;
+       case MP_EQ:  printf("number = 7"); break;
+       case MP_LT:  printf("number < 7"); break;
+   \}
+
+   /* we're done with it. */ 
+   mp_clear(&number);
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+If this program functions properly it will print out the following.
+
+\begin{alltt}
+number < 7
+\end{alltt}
+
+\section{Logical Operations}
+
+Logical operations are operations that can be performed either with simple shifts or boolean operators such as
+AND, XOR and OR directly.  These operations are very quick.
+
+\subsection{Multiplication by two}
+
+Multiplications and divisions by any power of two can be performed with quick logical shifts either left or
+right depending on the operation.  
+
+When multiplying or dividing by two a special case routine can be used which are as follows.
+\index{mp\_mul\_2} \index{mp\_div\_2}
+\begin{alltt}
+int mp_mul_2(mp_int * a, mp_int * b);
+int mp_div_2(mp_int * a, mp_int * b);
+\end{alltt}
+
+The former will assign twice $a$ to $b$ while the latter will assign half $a$ to $b$.  These functions are fast
+since the shift counts and maskes are hardcoded into the routines.
+
+\begin{small} \begin{alltt}
+int main(void)
+\{
+   mp_int number;
+   int result;
+
+   if ((result = mp_init(&number)) != MP_OKAY) \{
+      printf("Error initializing the number.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+ 
+   /* set the number to 5 */
+   mp_set(&number, 5);
+
+   /* multiply by two */
+   if ((result = mp\_mul\_2(&number, &number)) != MP_OKAY) \{
+      printf("Error multiplying the number.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+   switch(mp_cmp_d(&number, 7)) \{
+       case MP_GT:  printf("2*number > 7"); break;
+       case MP_EQ:  printf("2*number = 7"); break;
+       case MP_LT:  printf("2*number < 7"); break;
+   \}
+
+   /* now divide by two */
+   if ((result = mp\_div\_2(&number, &number)) != MP_OKAY) \{
+      printf("Error dividing the number.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+   switch(mp_cmp_d(&number, 7)) \{
+       case MP_GT:  printf("2*number/2 > 7"); break;
+       case MP_EQ:  printf("2*number/2 = 7"); break;
+       case MP_LT:  printf("2*number/2 < 7"); break;
+   \}
+
+   /* we're done with it. */ 
+   mp_clear(&number);
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt} \end{small}
+
+If this program is successful it will print out the following text.
+
+\begin{alltt}
+2*number > 7
+2*number/2 < 7
+\end{alltt}
+
+Since $10 > 7$ and $5 < 7$.  To multiply by a power of two the following function can be used.
+
+\index{mp\_mul\_2d}
+\begin{alltt}
+int mp_mul_2d(mp_int * a, int b, mp_int * c);
+\end{alltt}
+
+This will multiply $a$ by $2^b$ and store the result in ``c''.  If the value of $b$ is less than or equal to 
+zero the function will copy $a$ to ``c'' without performing any further actions.  
+
+To divide by a power of two use the following.
+
+\index{mp\_div\_2d}
+\begin{alltt}
+int mp_div_2d (mp_int * a, int b, mp_int * c, mp_int * d);
+\end{alltt}
+Which will divide $a$ by $2^b$, store the quotient in ``c'' and the remainder in ``d'.  If $b \le 0$ then the
+function simply copies $a$ over to ``c'' and zeroes $d$.  The variable $d$ may be passed as a \textbf{NULL}
+value to signal that the remainder is not desired.
+
+\subsection{Polynomial Basis Operations}
+
+Strictly speaking the organization of the integers within the mp\_int structures is what is known as a 
+``polynomial basis''.  This simply means a field element is stored by divisions of a radix.  For example, if
+$f(x) = \sum_{i=0}^{k} y_ix^k$ for any vector $\vec y$ then the array of digits in $\vec y$ are said to be 
+the polynomial basis representation of $z$ if $f(\beta) = z$ for a given radix $\beta$.  
+
+To multiply by the polynomial $g(x) = x$ all you have todo is shift the digits of the basis left one place.  The
+following function provides this operation.
+
+\index{mp\_lshd}
+\begin{alltt}
+int mp_lshd (mp_int * a, int b);
+\end{alltt}
+
+This will multiply $a$ in place by $x^b$ which is equivalent to shifting the digits left $b$ places and inserting zeroes
+in the least significant digits.  Similarly to divide by a power of $x$ the following function is provided.
+
+\index{mp\_rshd}
+\begin{alltt}
+void mp_rshd (mp_int * a, int b)
+\end{alltt}
+This will divide $a$ in place by $x^b$ and discard the remainder.  This function cannot fail as it performs the operations
+in place and no new digits are required to complete it.
+
+\subsection{AND, OR and XOR Operations}
+
+While AND, OR and XOR operations are not typical ``bignum functions'' they can be useful in several instances.  The
+three functions are prototyped as follows.
+
+\index{mp\_or} \index{mp\_and} \index{mp\_xor}
+\begin{alltt}
+int mp_or  (mp_int * a, mp_int * b, mp_int * c);
+int mp_and (mp_int * a, mp_int * b, mp_int * c);
+int mp_xor (mp_int * a, mp_int * b, mp_int * c);
+\end{alltt}
+
+Which compute $c = a \odot b$ where $\odot$ is one of OR, AND or XOR.  
+
+\section{Addition and Subtraction}
+
+To compute an addition or subtraction the following two functions can be used.
+
+\index{mp\_add} \index{mp\_sub}
+\begin{alltt}
+int mp_add (mp_int * a, mp_int * b, mp_int * c);
+int mp_sub (mp_int * a, mp_int * b, mp_int * c)
+\end{alltt}
+
+Which perform $c = a \odot b$ where $\odot$ is one of signed addition or subtraction.  The operations are fully sign
+aware.
+
+\section{Sign Manipulation}
+\subsection{Negation}
+\label{sec:NEG}
+Simple integer negation can be performed with the following.
+
+\index{mp\_neg}
+\begin{alltt}
+int mp_neg (mp_int * a, mp_int * b);
+\end{alltt}
+
+Which assigns $-a$ to $b$.  
+
+\subsection{Absolute}
+Simple integer absolutes can be performed with the following.
+
+\index{mp\_neg}
+\begin{alltt}
+int mp_abs (mp_int * a, mp_int * b);
+\end{alltt}
+
+Which assigns $\vert a \vert$ to $b$.  
+
+\section{Integer Division and Remainder}
+To perform a complete and general integer division with remainder use the following function.
+
+\index{mp\_div}
+\begin{alltt}
+int mp_div (mp_int * a, mp_int * b, mp_int * c, mp_int * d);
+\end{alltt}
+                                                        
+This divides $a$ by $b$ and stores the quotient in $c$ and $d$.  The signed quotient is computed such that 
+$bc + d = a$.  Note that either of $c$ or $d$ can be set to \textbf{NULL} if their value is not required.  If 
+$b$ is zero the function returns \textbf{MP\_VAL}.  
+
+
+\chapter{Multiplication and Squaring}
+\section{Multiplication}
+A full signed integer multiplication can be performed with the following.
+\index{mp\_mul}
+\begin{alltt}
+int mp_mul (mp_int * a, mp_int * b, mp_int * c);
+\end{alltt}
+Which assigns the full signed product $ab$ to $c$.  This function actually breaks into one of four cases which are 
+specific multiplication routines optimized for given parameters.  First there are the Toom-Cook multiplications which
+should only be used with very large inputs.  This is followed by the Karatsuba multiplications which are for moderate
+sized inputs.  Then followed by the Comba and baseline multipliers.
+
+Fortunately for the developer you don't really need to know this unless you really want to fine tune the system.  mp\_mul()
+will determine on its own\footnote{Some tweaking may be required.} what routine to use automatically when it is called.
+
+\begin{alltt}
+int main(void)
+\{
+   mp_int number1, number2;
+   int result;
+
+   /* Initialize the numbers */
+   if ((result = mp_init_multi(&number1, 
+                               &number2, NULL)) != MP_OKAY) \{
+      printf("Error initializing the numbers.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+   /* set the terms */
+   if ((result = mp_set_int(&number, 257)) != MP_OKAY) \{
+      printf("Error setting number1.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+ 
+   if ((result = mp_set_int(&number2, 1023)) != MP_OKAY) \{
+      printf("Error setting number2.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+   /* multiply them */
+   if ((result = mp_mul(&number1, &number2,
+                        &number1)) != MP_OKAY) \{
+      printf("Error multiplying terms.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+   /* display */
+   printf("number1 * number2 == \%lu", mp_get_int(&number1));
+
+   /* free terms and return */
+   mp_clear_multi(&number1, &number2, NULL);
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt}   
+
+If this program succeeds it shall output the following.
+
+\begin{alltt}
+number1 * number2 == 262911
+\end{alltt}
+
+\section{Squaring}
+Since squaring can be performed faster than multiplication it is performed it's own function instead of just using
+mp\_mul().
+
+\index{mp\_sqr}
+\begin{alltt}
+int mp_sqr (mp_int * a, mp_int * b);
+\end{alltt}
+
+Will square $a$ and store it in $b$.  Like the case of multiplication there are four different squaring
+algorithms all which can be called from mp\_sqr().  It is ideal to use mp\_sqr over mp\_mul when squaring terms.
+
+\section{Tuning Polynomial Basis Routines}
+
+Both of the Toom-Cook and Karatsuba multiplication algorithms are faster than the traditional $O(n^2)$ approach that
+the Comba and baseline algorithms use.  At $O(n^{1.464973})$ and $O(n^{1.584962})$ running times respectfully they require 
+considerably less work.  For example, a 10000-digit multiplication would take roughly 724,000 single precision
+multiplications with Toom-Cook or 100,000,000 single precision multiplications with the standard Comba (a factor
+of 138).
+
+So why not always use Karatsuba or Toom-Cook?   The simple answer is that they have so much overhead that they're not
+actually faster than Comba until you hit distinct  ``cutoff'' points.  For Karatsuba with the default configuration, 
+GCC 3.3.1 and an Athlon XP processor the cutoff point is roughly 110 digits (about 70 for the Intel P4).  That is, at 
+110 digits Karatsuba and Comba multiplications just about break even and for 110+ digits Karatsuba is faster.
+
+Toom-Cook has incredible overhead and is probably only useful for very large inputs.  So far no known cutoff points 
+exist and for the most part I just set the cutoff points very high to make sure they're not called.
+
+A demo program in the ``etc/'' directory of the project called ``tune.c'' can be used to find the cutoff points.  This
+can be built with GCC as follows
+
+\begin{alltt}
+make XXX
+\end{alltt}
+Where ``XXX'' is one of the following entries from the table \ref{fig:tuning}.
+
+\begin{figure}[here]
+\begin{center}
+\begin{small}
+\begin{tabular}{|l|l|}
+\hline \textbf{Value of XXX} & \textbf{Meaning} \\
+\hline tune & Builds portable tuning application \\
+\hline tune86 & Builds x86 (pentium and up) program for COFF \\
+\hline tune86c & Builds x86 program for Cygwin \\
+\hline tune86l & Builds x86 program for Linux (ELF format) \\
+\hline
+\end{tabular}
+\end{small}
+\end{center}
+\caption{Build Names for Tuning Programs}
+\label{fig:tuning}
+\end{figure}
+
+When the program is running it will output a series of measurements for different cutoff points.  It will first find
+good Karatsuba squaring and multiplication points.  Then it proceeds to find Toom-Cook points.  Note that the Toom-Cook
+tuning takes a very long time as the cutoff points are likely to be very high.
+
+\chapter{Modular Reduction}
+
+Modular reduction is process of taking the remainder of one quantity divided by another.  Expressed 
+as (\ref{eqn:mod}) the modular reduction is equivalent to the remainder of $b$ divided by $c$.  
+
+\begin{equation}
+a \equiv b \mbox{ (mod }c\mbox{)}
+\label{eqn:mod}
+\end{equation}
+
+Of particular interest to cryptography are reductions where $b$ is limited to the range $0 \le b < c^2$ since particularly 
+fast reduction algorithms can be written for the limited range.  
+
+Note that one of the four optimized reduction algorithms are automatically chosen in the modular exponentiation
+algorithm mp\_exptmod when an appropriate modulus is detected.  
+
+\section{Straight Division}
+In order to effect an arbitrary modular reduction the following algorithm is provided.
+
+\index{mp\_mod}
+\begin{alltt}
+int mp_mod(mp_int *a, mp_int *b, mp_int *c);
+\end{alltt}
+
+This reduces $a$ modulo $b$ and stores the result in $c$.  The sign of $c$ shall agree with the sign 
+of $b$.  This algorithm accepts an input $a$ of any range and is not limited by $0 \le a < b^2$.
+
+\section{Barrett Reduction}
+
+Barrett reduction is a generic optimized reduction algorithm that requires pre--computation to achieve
+a decent speedup over straight division.  First a $mu$ value must be precomputed with the following function.
+
+\index{mp\_reduce\_setup}
+\begin{alltt}
+int mp_reduce_setup(mp_int *a, mp_int *b);
+\end{alltt}
+
+Given a modulus in $b$ this produces the required $mu$ value in $a$.  For any given modulus this only has to
+be computed once.  Modular reduction can now be performed with the following.
+
+\index{mp\_reduce}
+\begin{alltt}
+int mp_reduce(mp_int *a, mp_int *b, mp_int *c);
+\end{alltt}
+
+This will reduce $a$ in place modulo $b$ with the precomputed $mu$ value in $c$.  $a$ must be in the range
+$0 \le a < b^2$.
+
+\begin{alltt}
+int main(void)
+\{
+   mp_int   a, b, c, mu;
+   int      result;
+
+   /* initialize a,b to desired values, mp_init mu, 
+    * c and set c to 1...we want to compute a^3 mod b 
+    */
+
+   /* get mu value */
+   if ((result = mp_reduce_setup(&mu, b)) != MP_OKAY) \{
+      printf("Error getting mu.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+   /* square a to get c = a^2 */
+   if ((result = mp_sqr(&a, &c)) != MP_OKAY) \{
+      printf("Error squaring.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+   /* now reduce `c' modulo b */
+   if ((result = mp_reduce(&c, &b, &mu)) != MP_OKAY) \{
+      printf("Error reducing.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+   
+   /* multiply a to get c = a^3 */
+   if ((result = mp_mul(&a, &c, &c)) != MP_OKAY) \{
+      printf("Error reducing.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+   /* now reduce `c' modulo b  */
+   if ((result = mp_reduce(&c, &b, &mu)) != MP_OKAY) \{
+      printf("Error reducing.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+  
+   /* c now equals a^3 mod b */
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt} 
+
+This program will calculate $a^3 \mbox{ mod }b$ if all the functions succeed.  
+
+\section{Montgomery Reduction}
+
+Montgomery is a specialized reduction algorithm for any odd moduli.  Like Barrett reduction a pre--computation
+step is required.  This is accomplished with the following.
+
+\index{mp\_montgomery\_setup}
+\begin{alltt}
+int mp_montgomery_setup(mp_int *a, mp_digit *mp);
+\end{alltt}
+
+For the given odd moduli $a$ the precomputation value is placed in $mp$.  The reduction is computed with the 
+following.
+
+\index{mp\_montgomery\_reduce}
+\begin{alltt}
+int mp_montgomery_reduce(mp_int *a, mp_int *m, mp_digit mp);
+\end{alltt}
+This reduces $a$ in place modulo $m$ with the pre--computed value $mp$.   $a$ must be in the range
+$0 \le a < b^2$.
+
+Montgomery reduction is faster than Barrett reduction for moduli smaller than the ``comba'' limit.  With the default
+setup for instance, the limit is $127$ digits ($3556$--bits).   Note that this function is not limited to
+$127$ digits just that it falls back to a baseline algorithm after that point.  
+
+An important observation is that this reduction does not return $a \mbox{ mod }m$ but $aR^{-1} \mbox{ mod }m$ 
+where $R = \beta^n$, $n$ is the n number of digits in $m$ and $\beta$ is radix used (default is $2^{28}$).  
+
+To quickly calculate $R$ the following function was provided.
+
+\index{mp\_montgomery\_calc\_normalization}
+\begin{alltt}
+int mp_montgomery_calc_normalization(mp_int *a, mp_int *b);
+\end{alltt}
+Which calculates $a = R$ for the odd moduli $b$ without using multiplication or division.  
+
+The normal modus operandi for Montgomery reductions is to normalize the integers before entering the system.  For
+example, to calculate $a^3 \mbox { mod }b$ using Montgomery reduction the value of $a$ can be normalized by
+multiplying it by $R$.  Consider the following code snippet.
+
+\begin{alltt}
+int main(void)
+\{
+   mp_int   a, b, c, R;
+   mp_digit mp;
+   int      result;
+
+   /* initialize a,b to desired values, 
+    * mp_init R, c and set c to 1.... 
+    */
+
+   /* get normalization */
+   if ((result = mp_montgomery_calc_normalization(&R, b)) != MP_OKAY) \{
+      printf("Error getting norm.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+   /* get mp value */
+   if ((result = mp_montgomery_setup(&c, &mp)) != MP_OKAY) \{
+      printf("Error setting up montgomery.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+   /* normalize `a' so now a is equal to aR */
+   if ((result = mp_mulmod(&a, &R, &b, &a)) != MP_OKAY) \{
+      printf("Error computing aR.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+   /* square a to get c = a^2R^2 */
+   if ((result = mp_sqr(&a, &c)) != MP_OKAY) \{
+      printf("Error squaring.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+   /* now reduce `c' back down to c = a^2R^2 * R^-1 == a^2R */
+   if ((result = mp_montgomery_reduce(&c, &b, mp)) != MP_OKAY) \{
+      printf("Error reducing.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+   
+   /* multiply a to get c = a^3R^2 */
+   if ((result = mp_mul(&a, &c, &c)) != MP_OKAY) \{
+      printf("Error reducing.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+   /* now reduce `c' back down to c = a^3R^2 * R^-1 == a^3R */
+   if ((result = mp_montgomery_reduce(&c, &b, mp)) != MP_OKAY) \{
+      printf("Error reducing.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+   
+   /* now reduce (again) `c' back down to c = a^3R * R^-1 == a^3 */
+   if ((result = mp_montgomery_reduce(&c, &b, mp)) != MP_OKAY) \{
+      printf("Error reducing.  \%s", 
+             mp_error_to_string(result));
+      return EXIT_FAILURE;
+   \}
+
+   /* c now equals a^3 mod b */
+
+   return EXIT_SUCCESS;
+\}
+\end{alltt} 
+
+This particular example does not look too efficient but it demonstrates the point of the algorithm.  By 
+normalizing the inputs the reduced results are always of the form $aR$ for some variable $a$.  This allows
+a single final reduction to correct for the normalization and the fast reduction used within the algorithm.
+
+For more details consider examining the file \textit{bn\_mp\_exptmod\_fast.c}.
+
+\section{Restricted Dimminished Radix}
+
+``Dimminished Radix'' reduction refers to reduction with respect to moduli that are ameniable to simple
+digit shifting and small multiplications.  In this case the ``restricted'' variant refers to moduli of the
+form $\beta^k - p$ for some $k \ge 0$ and $0 < p < \beta$ where $\beta$ is the radix (default to $2^{28}$).  
+
+As in the case of Montgomery reduction there is a pre--computation phase required for a given modulus.
+
+\index{mp\_dr\_setup}
+\begin{alltt}
+void mp_dr_setup(mp_int *a, mp_digit *d);
+\end{alltt}
+
+This computes the value required for the modulus $a$ and stores it in $d$.  This function cannot fail
+and does not return any error codes.  After the pre--computation a reduction can be performed with the
+following.
+
+\index{mp\_dr\_reduce}
+\begin{alltt}
+int mp_dr_reduce(mp_int *a, mp_int *b, mp_digit mp);
+\end{alltt}
+
+This reduces $a$ in place modulo $b$ with the pre--computed value $mp$.  $b$ must be of a restricted
+dimminished radix form and $a$ must be in the range $0 \le a < b^2$.  Dimminished radix reductions are 
+much faster than both Barrett and Montgomery reductions as they have a much lower asymtotic running time.  
+
+Since the moduli are restricted this algorithm is not particularly useful for something like Rabin, RSA or
+BBS cryptographic purposes.  This reduction algorithm is useful for Diffie-Hellman and ECC where fixed
+primes are acceptable.  
+
+Note that unlike Montgomery reduction there is no normalization process.  The result of this function is
+equal to the correct residue.
+
+\section{Unrestricted Dimminshed Radix}
+
+Unrestricted reductions work much like the restricted counterparts except in this case the moduli is of the 
+form $2^k - p$ for $0 < p < \beta$.  In this sense the unrestricted reductions are more flexible as they 
+can be applied to a wider range of numbers.  
+
+\index{mp\_reduce\_2k\_setup}
+\begin{alltt}
+int mp_reduce_2k_setup(mp_int *a, mp_digit *d);
+\end{alltt}
+
+This will compute the required $d$ value for the given moduli $a$.  
+
+\index{mp\_reduce\_2k}
+\begin{alltt}
+int mp_reduce_2k(mp_int *a, mp_int *n, mp_digit d);
+\end{alltt}
+
+This will reduce $a$ in place modulo $n$ with the pre--computed value $d$.  From my experience this routine is 
+slower than mp\_dr\_reduce but faster for most moduli sizes than the Montgomery reduction.  
+
+\chapter{Exponentiation}
+\section{Single Digit Exponentiation}
+\index{mp\_expt\_d}
+\begin{alltt}
+int mp_expt_d (mp_int * a, mp_digit b, mp_int * c)
+\end{alltt}
+This computes $c = a^b$ using a simple binary left-to-right algorithm.  It is faster than repeated multiplications by 
+$a$ for all values of $b$ greater than three.  
+
+\section{Modular Exponentiation}
+\index{mp\_exptmod}
+\begin{alltt}
+int mp_exptmod (mp_int * G, mp_int * X, mp_int * P, mp_int * Y)
+\end{alltt}
+This computes $Y \equiv G^X \mbox{ (mod }P\mbox{)}$ using a variable width sliding window algorithm.  This function
+will automatically detect the fastest modular reduction technique to use during the operation.  For negative values of 
+$X$ the operation is performed as $Y \equiv (G^{-1} \mbox{ mod }P)^{\vert X \vert} \mbox{ (mod }P\mbox{)}$ provided that 
+$gcd(G, P) = 1$.
+
+This function is actually a shell around the two internal exponentiation functions.  This routine will automatically
+detect when Barrett, Montgomery, Restricted and Unrestricted Dimminished Radix based exponentiation can be used.  Generally
+moduli of the a ``restricted dimminished radix'' form lead to the fastest modular exponentiations.  Followed by Montgomery
+and the other two algorithms.
+
+\section{Root Finding}
+\index{mp\_n\_root}
+\begin{alltt}
+int mp_n_root (mp_int * a, mp_digit b, mp_int * c)
+\end{alltt}
+This computes $c = a^{1/b}$ such that $c^b \le a$ and $(c+1)^b > a$.  The implementation of this function is not 
+ideal for values of $b$ greater than three.  It will work but become very slow.  So unless you are working with very small
+numbers (less than 1000 bits) I'd avoid $b > 3$ situations.  Will return a positive root only for even roots and return
+a root with the sign of the input for odd roots.  For example, performing $4^{1/2}$ will return $2$ whereas $(-8)^{1/3}$ 
+will return $-2$.  
+
+This algorithm uses the ``Newton Approximation'' method and will converge on the correct root fairly quickly.  Since
+the algorithm requires raising $a$ to the power of $b$ it is not ideal to attempt to find roots for large
+values of $b$.  If particularly large roots are required then a factor method could be used instead.  For example,
+$a^{1/16}$ is equivalent to $\left (a^{1/4} \right)^{1/4}$.

+This will attempt to evenly divide $a$ by a list of primes\footnote{Default is the first 256 primes.} and store the 
+outcome in ``result''.  That is if $result = 0$ then $a$ is not divisible by the primes, otherwise it is.  Note that 
+if the function does not return \textbf{MP\_OKAY} the value in ``result'' should be considered undefined\footnote{Currently
+the default is to set it to zero first.}.
+
+\section{Fermat Test}
+\index{mp\_prime\_fermat}
+\begin{alltt}
+int mp_prime_fermat (mp_int * a, mp_int * b, int *result)
+\end{alltt}
+Performs a Fermat primality test to the base $b$.  That is it computes $b^a \mbox{ mod }a$ and tests whether the value is
+equal to $b$ or not.  If the values are equal then $a$ is probably prime and $result$ is set to one.  Otherwise $result$
+is set to zero.
+
+\section{Miller-Rabin Test}
+\index{mp\_prime\_miller\_rabin}
+\begin{alltt}
+int mp_prime_miller_rabin (mp_int * a, mp_int * b, int *result)
+\end{alltt}
+Performs a Miller-Rabin test to the base $b$ of $a$.  This test is much stronger than the Fermat test and is very hard to
+fool (besides with Carmichael numbers).  If $a$ passes the test (therefore is probably prime) $result$ is set to one.  
+Otherwise $result$ is set to zero.  
+
+Note that is suggested that you use the Miller-Rabin test instead of the Fermat test since all of the failures of 
+Miller-Rabin are a subset of the failures of the Fermat test.
+
+\subsection{Required Number of Tests}
+Generally to ensure a number is very likely to be prime you have to perform the Miller-Rabin with at least a half-dozen
+or so unique bases.  However, it has been proven that the probability of failure goes down as the size of the input goes up.
+This is why a simple function has been provided to help out.
+
+\index{mp\_prime\_rabin\_miller\_trials}
+\begin{alltt}
+int mp_prime_rabin_miller_trials(int size)
+\end{alltt}
+This returns the number of trials required for a $2^{-96}$ (or lower) probability of failure for a given ``size'' expressed
+in bits.  This comes in handy specially since larger numbers are slower to test.  For example, a 512-bit number would
+require ten tests whereas a 1024-bit number would only require four tests. 
+
+You should always still perform a trial division before a Miller-Rabin test though.
+
+\section{Primality Testing}
+\index{mp\_prime\_is\_prime}
+\begin{alltt}
+int mp_prime_is_prime (mp_int * a, int t, int *result)
+\end{alltt}
+This will perform a trial division followed by $t$ rounds of Miller-Rabin tests on $a$ and store the result in $result$.  
+If $a$ passes all of the tests $result$ is set to one, otherwise it is set to zero.  Note that $t$ is bounded by 
+$1 \le t < PRIME\_SIZE$ where $PRIME\_SIZE$ is the number of primes in the prime number table (by default this is $256$).
+
+\section{Next Prime}
+\index{mp\_prime\_next\_prime}
+\begin{alltt}
+int mp_prime_next_prime(mp_int *a, int t, int bbs_style)
+\end{alltt}
+This finds the next prime after $a$ that passes mp\_prime\_is\_prime() with $t$ tests.  Set $bbs\_style$ to one if you 
+want only the next prime congruent to $3 \mbox{ mod } 4$, otherwise set it to zero to find any next prime.  
+
+\section{Random Primes}
+\index{mp\_prime\_random}
+\begin{alltt}
+int mp_prime_random(mp_int *a, int t, int size, int bbs, 
+                    ltm_prime_callback cb, void *dat)
+\end{alltt}
+This will find a prime greater than $256^{size}$ which can be ``bbs\_style'' or not depending on $bbs$ and must pass
+$t$ rounds of tests.  The ``ltm\_prime\_callback'' is a typedef for 
+
+\begin{alltt}
+typedef int ltm_prime_callback(unsigned char *dst, int len, void *dat);
+\end{alltt}
+
+Which is a function that must read $len$ bytes (and return the amount stored) into $dst$.  The $dat$ variable is simply
+copied from the original input.  It can be used to pass RNG context data to the callback.  The function 
+mp\_prime\_random() is more suitable for generating primes which must be secret (as in the case of RSA) since there 
+is no skew on the least significant bits.
+
+\textit{Note:}  As of v0.30 of the LibTomMath library this function has been deprecated.  It is still available
+but users are encouraged to use the new mp\_prime\_random\_ex() function instead.
+
+\subsection{Extended Generation}
+\index{mp\_prime\_random\_ex}
+\begin{alltt}
+int mp_prime_random_ex(mp_int *a,    int t, 
+                       int     size, int flags, 
+                       ltm_prime_callback cb, void *dat);
+\end{alltt}
+This will generate a prime in $a$ using $t$ tests of the primality testing algorithms.  The variable $size$
+specifies the bit length of the prime desired.  The variable $flags$ specifies one of several options available
+(see fig. \ref{fig:primeopts}) which can be OR'ed together.  The callback parameters are used as in 
+mp\_prime\_random().
+

+\chapter{Input and Output}
+\section{ASCII Conversions}
+\subsection{To ASCII}
+\index{mp\_toradix}
+\begin{alltt}
+int mp_toradix (mp_int * a, char *str, int radix);
+\end{alltt}
+This still store $a$ in ``str'' as a base-``radix'' string of ASCII chars.  This function appends a NUL character
+to terminate the string.  Valid values of ``radix'' line in the range $[2, 64]$.  To determine the size (exact) required
+by the conversion before storing any data use the following function.
+
+\index{mp\_radix\_size}
+\begin{alltt}
+int mp_radix_size (mp_int * a, int radix, int *size)
+\end{alltt}
+This stores in ``size'' the number of characters (including space for the NUL terminator) required.  Upon error this 
+function returns an error code and ``size'' will be zero.  
+
+\subsection{From ASCII}
+\index{mp\_read\_radix}
+\begin{alltt}
+int mp_read_radix (mp_int * a, char *str, int radix);
+\end{alltt}
+This will read the base-``radix'' NUL terminated string from ``str'' into $a$.  It will stop reading when it reads a
+character it does not recognize (which happens to include th NUL char... imagine that...).  A single leading $-$ sign
+can be used to denote a negative number.
+
+\section{Binary Conversions}
+
+Converting an mp\_int to and from binary is another keen idea.
+
+\index{mp\_unsigned\_bin\_size}
+\begin{alltt}
+int mp_unsigned_bin_size(mp_int *a);
+\end{alltt}
+
+This will return the number of bytes (octets) required to store the unsigned copy of the integer $a$.
+
+\index{mp\_to\_unsigned\_bin}
+\begin{alltt}
+int mp_to_unsigned_bin(mp_int *a, unsigned char *b);
+\end{alltt}
+This will store $a$ into the buffer $b$ in big--endian format.  Fortunately this is exactly what DER (or is it ASN?)
+requires.  It does not store the sign of the integer.
+
+\index{mp\_read\_unsigned\_bin}
+\begin{alltt}
+int mp_read_unsigned_bin(mp_int *a, unsigned char *b, int c);
+\end{alltt}
+This will read in an unsigned big--endian array of bytes (octets) from $b$ of length $c$ into $a$.  The resulting
+integer $a$ will always be positive.
+
+For those who acknowledge the existence of negative numbers (heretic!) there are ``signed'' versions of the
+previous functions.
+
+\begin{alltt}
+int mp_signed_bin_size(mp_int *a);
+int mp_read_signed_bin(mp_int *a, unsigned char *b, int c);
+int mp_to_signed_bin(mp_int *a, unsigned char *b);
+\end{alltt}
+They operate essentially the same as the unsigned copies except they prefix the data with zero or non--zero
+byte depending on the sign.  If the sign is zpos (e.g. not negative) the prefix is zero, otherwise the prefix
+is non--zero.  
+
+\chapter{Algebraic Functions}
+\section{Extended Euclidean Algorithm}
+\index{mp\_exteuclid}
+\begin{alltt}
+int mp_exteuclid(mp_int *a, mp_int *b, 
+                 mp_int *U1, mp_int *U2, mp_int *U3);
+\end{alltt}
+
+This finds the triple U1/U2/U3 using the Extended Euclidean algorithm such that the following equation holds.
+
+\begin{equation}
+a \cdot U1 + b \cdot U2 = U3
+\end{equation}
+
+Any of the U1/U2/U3 paramters can be set to \textbf{NULL} if they are not desired.  
+
+\section{Greatest Common Divisor}
+\index{mp\_gcd}
+\begin{alltt}
+int mp_gcd (mp_int * a, mp_int * b, mp_int * c)
+\end{alltt}
+This will compute the greatest common divisor of $a$ and $b$ and store it in $c$.
+
+\section{Least Common Multiple}
+\index{mp\_lcm}
+\begin{alltt}
+int mp_lcm (mp_int * a, mp_int * b, mp_int * c)
+\end{alltt}
+This will compute the least common multiple of $a$ and $b$ and store it in $c$.
+
+\section{Jacobi Symbol}
+\index{mp\_jacobi}
+\begin{alltt}
+int mp_jacobi (mp_int * a, mp_int * p, int *c)
+\end{alltt}
+This will compute the Jacobi symbol for $a$ with respect to $p$.  If $p$ is prime this essentially computes the Legendre
+symbol.  The result is stored in $c$ and can take on one of three values $\lbrace -1, 0, 1 \rbrace$.  If $p$ is prime
+then the result will be $-1$ when $a$ is not a quadratic residue modulo $p$.  The result will be $0$ if $a$ divides $p$
+and the result will be $1$ if $a$ is a quadratic residue modulo $p$.  
+
+\section{Modular Inverse}
+\index{mp\_invmod}
+\begin{alltt}
+int mp_invmod (mp_int * a, mp_int * b, mp_int * c)
+\end{alltt}
+Computes the multiplicative inverse of $a$ modulo $b$ and stores the result in $c$ such that $ac \equiv 1 \mbox{ (mod }b\mbox{)}$.
+
+\section{Single Digit Functions}
+
+For those using small numbers (\textit{snicker snicker}) there are several ``helper'' functions
+
+\index{mp\_add\_d} \index{mp\_sub\_d} \index{mp\_mul\_d} \index{mp\_div\_d} \index{mp\_mod\_d}
+\begin{alltt}
+int mp_add_d(mp_int *a, mp_digit b, mp_int *c);
+int mp_sub_d(mp_int *a, mp_digit b, mp_int *c);
+int mp_mul_d(mp_int *a, mp_digit b, mp_int *c);
+int mp_div_d(mp_int *a, mp_digit b, mp_int *c, mp_digit *d);
+int mp_mod_d(mp_int *a, mp_digit b, mp_digit *c);
+\end{alltt}
+
+These work like the full mp\_int capable variants except the second parameter $b$ is a mp\_digit.  These
+functions fairly handy if you have to work with relatively small numbers since you will not have to allocate
+an entire mp\_int to store a number like $1$ or $2$.

+v0.33  -- Fixed "small" variant for mp_div() which would munge with negative dividends...
+       -- Fixed bug in mp_prime_random_ex() which would set the most significant byte to zero when
+          no special flags were set
+       -- Fixed overflow [minor] bug in fast_s_mp_sqr()
+       -- Made the makefiles easier to configure the group/user that ltm will install as
+       -- Fixed "final carry" bug in comba multipliers. (Volkan Ceylan)
+       -- Matt Johnston pointed out a missing semi-colon in mp_exptmod
+
+October 29th, 2004
+v0.32  -- Added "makefile.shared" for shared object support
+       -- Added more to the build options/configs in the manual
+       -- Started the Depends framework, wrote dep.pl to scan deps and 
+          produce "callgraph.txt" ;-)
+       -- Wrote SC_RSA_1 which will enable close to the minimum required to perform
+          RSA on 32-bit [or 64-bit] platforms with LibTomCrypt
+       -- Merged in the small/slower mp_div replacement.  You can now toggle which
+          you want to use as your mp_div() at build time.  Saves roughly 8KB or so.
+       -- Renamed a few files and changed some comments to make depends system work better.
+          (No changes to function names)
+       -- Merged in new Combas that perform 2 reads per inner loop instead of the older 
+          3reads/2writes per inner loop of the old code.  Really though if you want speed
+          learn to use TomsFastMath ;-)
+
+August 9th, 2004
+v0.31  -- "profiled" builds now :-) new timings for Intel Northwoods
+       -- Added "pretty" build target
+       -- Update mp_init() to actually assign 0's instead of relying on calloc()
+       -- "Wolfgang Ehrhardt" <Wolfgang.Ehrhardt@munich.netsurf.de> found a bug in mp_mul() where if
+          you multiply a negative by zero you get negative zero as the result.  Oops.
+       -- J Harper from PeerSec let me toy with his AMD64 and I got 60-bit digits working properly
+          [this also means that I fixed a bug where if sizeof(int) < sizeof(mp_digit) it would bug]
+
+April 11th, 2004
+v0.30  -- Added "mp_toradix_n" which stores upto "n-1" least significant digits of an mp_int
+       -- Johan Lindh sent a patch so MSVC wouldn't whine about redefining malloc [in weird dll modes]
+       -- Henrik Goldman spotted a missing OPT_CAST in mp_fwrite()
+       -- Tuned tommath.h so that when MP_LOW_MEM is defined MP_PREC shall be reduced.
+          [I also allow MP_PREC to be externally defined now]
+       -- Sped up mp_cnt_lsb() by using a 4x4 table [e.g. 4x speedup]
+       -- Added mp_prime_random_ex() which is a more versatile prime generator accurate to
+          exact bit lengths (unlike the deprecated but still available mp_prime_random() which
+          is only accurate to byte lengths).  See the new LTM_PRIME_* flags ;-)
+       -- Alex Polushin contributed an optimized mp_sqrt() as well as mp_get_int() and mp_is_square().
+          I've cleaned them all up to be a little more consistent [along with one bug fix] for this release.
+       -- Added mp_init_set and mp_init_set_int to initialize and set small constants with one function
+          call.
+       -- Removed /etclib directory [um LibTomPoly deprecates this].
+       -- Fixed mp_mod() so the sign of the result agrees with the sign of the modulus.
+       ++ N.B.  My semester is almost up so expect updates to the textbook to be posted to the libtomcrypt.org 
+          website.  
+
+Jan 25th, 2004
+v0.29  ++ Note: "Henrik" from the v0.28 changelog refers to Henrik Goldman ;-)
+       -- Added fix to mp_shrink to prevent a realloc when used == 0 [e.g. realloc zero bytes???]
+       -- Made the mp_prime_rabin_miller_trials() function internal table smaller and also
+          set the minimum number of tests to two (sounds a bit safer).
+       -- Added a mp_exteuclid() which computes the extended euclidean algorithm.
+       -- Fixed a memory leak in s_mp_exptmod() [called when Barrett reduction is to be used] which would arise
+          if a multiplication or subsequent reduction failed [would not free the temp result].
+       -- Made an API change to mp_radix_size().  It now returns an error code and stores the required size
+          through an "int star" passed to it.
+
+Dec 24th, 2003
+v0.28  -- Henrik Goldman suggested I add casts to the montomgery code [stores into mu...] so compilers wouldn't
+          spew [erroneous] diagnostics... fixed.
+       -- Henrik Goldman also spotted two typos.  One in mp_radix_size() and another in mp_toradix().
+       -- Added fix to mp_shrink() to avoid a memory leak.
+       -- Added mp_prime_random() which requires a callback to make truly random primes of a given nature
+          (idea from chat with Niels Ferguson at Crypto'03)
+       -- Picked up a second wind.  I'm filled with Gooo.  Mission Gooo!
+       -- Removed divisions from mp_reduce_is_2k()
+       -- Sped up mp_div_d() [general case] to use only one division per digit instead of two.
+       -- Added the heap macros from LTC to LTM.  Now you can easily [by editing four lines of tommath.h]
+          change the name of the heap functions used in LTM [also compatible with LTC via MPI mode]
+       -- Added bn_prime_rabin_miller_trials() which gives the number of Rabin-Miller trials to achieve
+          a failure rate of less than 2^-96
+       -- fixed bug in fast_mp_invmod().  The initial testing logic was wrong.  An invalid input is not when
+          "a" and "b" are even it's when "b" is even [the algo is for odd moduli only].
+       -- Started a new manual [finally].  It is incomplete and will be finished as time goes on.  I had to stop
+          adding full demos around half way in chapter three so I could at least get a good portion of the
+          manual done.   If you really need help using the library you can always email me!
+       -- My Textbook is now included as part of the package [all Public Domain]
+
+Sept 19th, 2003
+v0.27  -- Removed changes.txt~ which was made by accident since "kate" decided it was
+          a good time to re-enable backups... [kde is fun!]
+       -- In mp_grow() "a->dp" is not overwritten by realloc call [re: memory leak]
+          Now if mp_grow() fails the mp_int is still valid and can be cleared via
+          mp_clear() to reclaim the memory.
+       -- Henrik Goldman found a buffer overflow bug in mp_add_d().  Fixed.
+       -- Cleaned up mp_mul_d() to be much easier to read and follow.
+
+Aug 29th, 2003
+v0.26  -- Fixed typo that caused warning with GCC 3.2
+       -- Martin Marcel noticed a bug in mp_neg() that allowed negative zeroes.
+          Also, Martin is the fellow who noted the bugs in mp_gcd() of 0.24/0.25.
+       -- Martin Marcel noticed an optimization [and slight bug] in mp_lcm().
+       -- Added fix to mp_read_unsigned_bin to prevent a buffer overflow.
+       -- Beefed up the comments in the baseline multipliers [and montgomery]
+       -- Added "mont" demo to the makefile.msvc in etc/
+       -- Optimized sign compares in mp_cmp from 4 to 2 cases.
+
+Aug 4th, 2003
+v0.25  -- Fix to mp_gcd again... oops (0,-a) == (-a, 0) == a
+       -- Fix to mp_clear which didn't reset the sign  [Greg Rose]
+       -- Added mp_error_to_string() to convert return codes to strings.  [Greg Rose]
+       -- Optimized fast_mp_invmod() to do the test for invalid inputs [both even]
+          first so temps don't have to be initialized if it's going to fail.
+       -- Optimized mp_gcd() by removing mp_div_2d calls for when one of the inputs
+          is odd.
+       -- Tons of new comments, some indentation fixups, etc.
+       -- mp_jacobi() returns MP_VAL if the modulus is less than or equal to zero.
+       -- fixed two typos in the header of each file :-)
+       -- LibTomMath is officially Public Domain [see LICENSE]
+
+July 15th, 2003
+v0.24  -- Optimized mp_add_d and mp_sub_d to not allocate temporary variables
+       -- Fixed mp_gcd() so the gcd of 0,0 is 0.  Allows the gcd operation to be chained
+          e.g. (0,0,a) == a [instead of 1]
+       -- Should be one of the last release for a while.  Working on LibTomMath book now.
+       -- optimized the pprime demo [/etc/pprime.c] to first make a huge table of single
+          digit primes then it reads them randomly instead of randomly choosing/testing single
+          digit primes.
+
+July 12th, 2003
+v0.23  -- Optimized mp_prime_next_prime() to not use mp_mod [via is_divisible()] in each
+          iteration.  Instead now a smaller table is kept of the residues which can be updated
+          without division.
+       -- Fixed a bug in next_prime() where an input of zero would be treated as odd and
+          have two added to it [to move to the next odd].
+       -- fixed a bug in prime_fermat() and prime_miller_rabin() which allowed the base
+          to be negative, zero or one.  Normally the test is only valid if the base is
+          greater than one.
+       -- changed the next_prime() prototype to accept a new parameter "bbs_style" which
+          will find the next prime congruent to 3 mod 4.  The default [bbs_style==0] will
+          make primes which are either congruent to 1 or 3 mod 4.
+       -- fixed mp_read_unsigned_bin() so that it doesn't include both code for
+          the case DIGIT_BIT < 8 and >= 8
+       -- optimized div_d() to easy out on division by 1 [or if a == 0] and use
+          logical shifts if the divisor is a power of two.
+       -- the default DIGIT_BIT type was not int for non-default builds.  Fixed.
+
+July 2nd, 2003
+v0.22  -- Fixed up mp_invmod so the result is properly in range now [was always congruent to the inverse...]
+       -- Fixed up s_mp_exptmod and mp_exptmod_fast so the lower half of the pre-computed table isn't allocated
+          which makes the algorithm use half as much ram.
+       -- Fixed the install script not to make the book :-) [which isn't included anyways]
+       -- added mp_cnt_lsb() which counts how many of the lsbs are zero
+       -- optimized mp_gcd() to use the new mp_cnt_lsb() to replace multiple divisions by two by a single division.
+       -- applied similar optimization to mp_prime_miller_rabin().
+       -- Fixed a bug in both mp_invmod() and fast_mp_invmod() which tested for odd
+          via "mp_iseven() == 0" which is not valid [since zero is not even either].
+
+June 19th, 2003
+v0.21  -- Fixed bug in mp_mul_d which would not handle sign correctly [would not always forward it]
+       -- Removed the #line lines from gen.pl [was in violation of ISO C]
+
+June 8th, 2003
+v0.20  -- Removed the book from the package.  Added the TDCAL license document.
+       -- This release is officially pure-bred TDCAL again [last officially TDCAL based release was v0.16]
+
+June 6th, 2003
+v0.19  -- Fixed a bug in mp_montgomery_reduce() which was introduced when I tweaked mp_rshd() in the previous release.
+          Essentially the digits were not trimmed before the compare which cause a subtraction to occur all the time.
+       -- Fixed up etc/tune.c a bit to stop testing new cutoffs after 16 failures [to find more optimal points].
+          Brute force ho!
+
+
+May 29th, 2003
+v0.18  -- Fixed a bug in s_mp_sqr which would handle carries properly just not very elegantly.
+          (e.g. correct result, just bad looking code)
+       -- Fixed bug in mp_sqr which still had a 512 constant instead of MP_WARRAY
+       -- Added Toom-Cook multipliers [needs tuning!]
+       -- Added efficient divide by 3 algorithm mp_div_3
+       -- Re-wrote mp_div_d to be faster than calling mp_div
+       -- Added in a donated BCC makefile and a single page LTM poster (ahalhabsi@sbcglobal.net)
+       -- Added mp_reduce_2k which reduces an input modulo n = 2**p - k for any single digit k
+       -- Made the exptmod system be aware of the 2k reduction algorithms.
+       -- Rewrote mp_dr_reduce to be smaller, simpler and easier to understand.
+
+May 17th, 2003
+v0.17  -- Benjamin Goldberg submitted optimized mp_add and mp_sub routines.  A new gen.pl as well
+          as several smaller suggestions.  Thanks!
+       -- removed call to mp_cmp in inner loop of mp_div and put mp_cmp_mag in its place :-)
+       -- Fixed bug in mp_exptmod that would cause it to fail for odd moduli when DIGIT_BIT != 28
+       -- mp_exptmod now also returns errors if the modulus is negative and will handle negative exponents
+       -- mp_prime_is_prime will now return true if the input is one of the primes in the prime table
+       -- Damian M Gryski (dgryski@uwaterloo.ca) found a index out of bounds error in the
+          mp_fast_s_mp_mul_high_digs function which didn't come up before.  (fixed)
+       -- Refactored the DR reduction code so there is only one function per file.
+       -- Fixed bug in the mp_mul() which would erroneously avoid the faster multiplier [comba] when it was
+          allowed.  The bug would not cause the incorrect value to be produced just less efficient (fixed)
+       -- Fixed similar bug in the Montgomery reduction code.
+       -- Added tons of (mp_digit) casts so the 7/15/28/31 bit digit code will work flawlessly out of the box.
+          Also added limited support for 64-bit machines with a 60-bit digit.  Both thanks to Tom Wu (tom@arcot.com)
+       -- Added new comments here and there, cleaned up some code [style stuff]
+       -- Fixed a lingering typo in mp_exptmod* that would set bitcnt to zero then one.  Very silly stuff :-)
+       -- Fixed up mp_exptmod_fast so it would set "redux" to the comba Montgomery reduction if allowed.  This
+          saves quite a few calls and if statements.
+       -- Added etc/mont.c a test of the Montgomery reduction [assuming all else works :-| ]
+       -- Fixed up etc/tune.c to use a wider test range [more appropriate] also added a x86 based addition which
+          uses RDTSC for high precision timing.
+       -- Updated demo/demo.c to remove MPI stuff [won't work anyways], made the tests run for 2 seconds each so its
+          not so insanely slow.  Also made the output space delimited [and fixed up various errors]
+       -- Added logs directory, logs/graph.dem which will use gnuplot to make a series of PNG files
+          that go with the pre-made index.html.  You have to build [via make timing] and run ltmtest first in the
+          root of the package.
+       -- Fixed a bug in mp_sub and mp_add where "-a - -a" or "-a + a" would produce -0 as the result [obviously invalid].
+       -- Fixed a bug in mp_rshd.  If the count == a.used it should zero/return [instead of shifting]
+       -- Fixed a "off-by-one" bug in mp_mul2d.  The initial size check on alloc would be off by one if the residue
+          shifting caused a carry.
+       -- Fixed a bug where s_mp_mul_digs() would not call the Comba based routine if allowed.  This made Barrett reduction
+          slower than it had to be.
+
+Mar 29th, 2003
+v0.16  -- Sped up mp_div by making normalization one shift call
+       -- Sped up mp_mul_2d/mp_div_2d by aliasing pointers :-)
+       -- Cleaned up mp_gcd to use the macros for odd/even detection
+       -- Added comments here and there, mostly there but occasionally here too.
+
+Mar 22nd, 2003
+v0.15  -- Added series of prime testing routines to lib
+       -- Fixed up etc/tune.c
+       -- Added DR reduction algorithm
+       -- Beefed up the manual more.
+       -- Fixed up demo/demo.c so it doesn't have so many warnings and it does the full series of
+          tests
+       -- Added "pre-gen" directory which will hold a "gen.pl"'ed copy of the entire lib [done at
+          zipup time so its always the latest]
+       -- Added conditional casts for C++ users [boo!]
+
+Mar 15th, 2003
+v0.14  -- Tons of manual updates
+       -- cleaned up the directory
+       -- added MSVC makefiles
+       -- source changes [that I don't recall]
+       -- Fixed up the lshd/rshd code to use pointer aliasing
+       -- Fixed up the mul_2d and div_2d to not call rshd/lshd unless needed
+       -- Fixed up etc/tune.c a tad
+       -- fixed up demo/demo.c to output comma-delimited results of timing
+          also fixed up timing demo to use a finer granularity for various functions
+       -- fixed up demo/demo.c testing to pause during testing so my Duron won't catch on fire
+          [stays around 31-35C during testing :-)]
+
+Feb 13th, 2003
+v0.13  -- tons of minor speed-ups in low level add, sub, mul_2 and div_2 which propagate
+          to other functions like mp_invmod, mp_div, etc...
+       -- Sped up mp_exptmod_fast by using new code to find R mod m [e.g. B^n mod m]
+       -- minor fixes
+
+Jan 17th, 2003
+v0.12  -- re-wrote the majority of the makefile so its more portable and will
+          install via "make install" on most *nix platforms
+       -- Re-packaged all the source as seperate files.  Means the library a single
+          file packagage any more.  Instead of just adding "bn.c" you have to add
+          libtommath.a
+       -- Renamed "bn.h" to "tommath.h"
+       -- Changes to the manual to reflect all of this
+       -- Used GNU Indent to clean up the source
+
+Jan 15th, 2003
+v0.11  -- More subtle fixes
+       -- Moved to gentoo linux [hurrah!] so made *nix specific fixes to the make process
+       -- Sped up the montgomery reduction code quite a bit
+       -- fixed up demo so when building timing for the x86 it assumes ELF format now
+
+Jan 9th, 2003
+v0.10  -- Pekka Riikonen suggested fixes to the radix conversion code.
+       -- Added baseline montgomery and comba montgomery reductions, sped up exptmods
+          [to a point, see bn.h for MONTGOMERY_EXPT_CUTOFF]
+
+Jan 6th, 2003
+v0.09  -- Updated the manual to reflect recent changes.  :-)
+       -- Added Jacobi function (mp_jacobi) to supplement the number theory side of the lib
+       -- Added a Mersenne prime finder demo in ./etc/mersenne.c
+
+Jan 2nd, 2003
+v0.08  -- Sped up the multipliers by moving the inner loop variables into a smaller scope
+       -- Corrected a bunch of small "warnings"
+       -- Added more comments
+       -- Made "mtest" be able to use /dev/random, /dev/urandom or stdin for RNG data
+       -- Corrected some bugs where error messages were potentially ignored
+       -- add etc/pprime.c program which makes numbers which are provably prime.
+
+Jan 1st, 2003
+v0.07  -- Removed alot of heap operations from core functions to speed them up
+       -- Added a root finding function [and mp_sqrt macro like from MPI]
+       -- Added more to manual
+
+Dec 31st, 2002
+v0.06  -- Sped up the s_mp_add, s_mp_sub which inturn sped up mp_invmod, mp_exptmod, etc...
+       -- Cleaned up the header a bit more
+
+Dec 30th, 2002
+v0.05  -- Builds with MSVC out of the box
+       -- Fixed a bug in mp_invmod w.r.t. even moduli
+       -- Made mp_toradix and mp_read_radix use char instead of unsigned char arrays
+       -- Fixed up exptmod to use fewer multiplications
+       -- Fixed up mp_init_size to use only one heap operation
+          -- Note there is a slight "off-by-one" bug in the library somewhere
+             without the padding (see the source for comment) the library
+             crashes in libtomcrypt.  Anyways a reasonable workaround is to pad the
+             numbers which will always correct it since as the numbers grow the padding
+             will still be beyond the end of the number
+       -- Added more to the manual
+
+Dec 29th, 2002
+v0.04  -- Fixed a memory leak in mp_to_unsigned_bin
+       -- optimized invmod code
+       -- Fixed bug in mp_div
+       -- use exchange instead of copy for results
+       -- added a bit more to the manual
+
+Dec 27th, 2002
+v0.03  -- Sped up s_mp_mul_high_digs by not computing the carries of the lower digits
+       -- Fixed a bug where mp_set_int wouldn't zero the value first and set the used member.
+       -- fixed a bug in s_mp_mul_high_digs where the limit placed on the result digits was not calculated properly
+       -- fixed bugs in add/sub/mul/sqr_mod functions where if the modulus and dest were the same it wouldn't work
+       -- fixed a bug in mp_mod and mp_mod_d concerning negative inputs
+       -- mp_mul_d didn't preserve sign
+       -- Many many many many fixes
+       -- Works in LibTomCrypt now :-)
+       -- Added iterations to the timing demos... more accurate.
+       -- Tom needs a job.
+
+Dec 26th, 2002
+v0.02  -- Fixed a few "slips" in the manual.  This is "LibTomMath" afterall :-)
+       -- Added mp_cmp_mag, mp_neg, mp_abs and mp_radix_size that were missing.
+       -- Sped up the fast [comba] multipliers more [yahoo!]
+
+Dec 25th,2002
+v0.01  -- Initial release.  Gimme a break.
+       -- Todo list,
+           add details to manual [e.g. algorithms]
+           more comments in code
+           example programs

+To use the pretty graphs you have to first build/run the ltmtest from the root directory of the package.  

+Todo this type 

+

+make timing ; ltmtest

+

+in the root.  It will run for a while [about ten minutes on most PCs] and produce a series of .log files in logs/.

+

+After doing that run "gnuplot graphs.dem" to make the PNGs.  If you managed todo that all so far just open index.html to view

+them all :-)

+

+Have fun
