 Certificates
 ------------
 
-Certificates in general are part of a public-key / private-key system.  In this system, each *principal*,
-(which may be a machine, or a person, or an organization) is assigned a unique two-part encryption key.
-One part of the key is public, and is called the *public key*; the other part is kept secret, and is called
-the *private key*.  The two parts are related, in that if you encrypt a message with one of the parts, you can
-decrypt it with the other part, and **only** with the other part.
-
-A certificate contains information about two principals.  It contains
-the name of a *subject*, and the subject's public key.  It also
-contains a statement by a second principal, the *issuer*, that the
-subject is who he claims to be, and that this is indeed the subject's
-public key.  The issuer's statement is signed with the issuer's
-private key, which only the issuer knows.  However, anyone can verify
-the issuer's statement by finding the issuer's public key, decrypting
-the statement with it, and comparing it to the other information in
-the certificate.  The certificate also contains information about the
-time period over which it is valid.  This is expressed as two fields,
-called "notBefore" and "notAfter".
-
-In the Python use of certificates, a client or server
-can use a certificate to prove who they are.  The other
-side of a network connection can also be required to produce a certificate,
-and that certificate can be validated to the satisfaction
-of the client or server that requires such validation.
-The connection attempt can be set to raise an exception if
-the validation fails.  Validation is done
-automatically, by the underlying OpenSSL framework; the
-application need not concern itself with its mechanics.
-But the application does usually need to provide
