* gh-99108: Refactor _sha256 & _sha512 into _sha2. (#101924)Gregory P. Smith2023-02-161-465/+0
| | | | | | | | | This merges their code. They're backed by the same single HACL* static library, having them be a single module simplifies maintenance. This should unbreak the wasm enscripten builds that currently fail due to linking in --whole-archive mode and the HACL* library appearing twice. Long unnoticed error fixed: _sha512.SHA384Type was doubly assigned and was actually SHA512Type. Nobody depends on those internal names. Also rename LIBHACL_ make vars to LIBHACL_SHA2_ in preperation for other future HACL things.
* gh-99108: Import SHA2-384/512 from HACL* (#101707)Jonathan Protzenko2023-02-141-0/+1
| | | | | | Replace the builtin hashlib implementations of SHA2-384 and SHA2-512 originally from LibTomCrypt with formally verified, side-channel resistant code from the [HACL*](https://github.com/hacl-star/hacl-star/) project. The builtins remain a fallback only used when OpenSSL does not provide them.
* gh-99108: Replace SHA2-224 & 256 with verified code from HACL* (#99109)Jonathan Protzenko2023-02-071-345/+53
| | | | | | | | | | | | | | | | | | | | | | replacing hashlib primitives (for the non-OpenSSL case) with verified implementations from HACL*. This is the first PR in the series, and focuses specifically on SHA2-256 and SHA2-224. This PR imports Hacl_Streaming_SHA2 into the Python tree. This is the HACL* implementation of SHA2, which combines a core implementation of SHA2 along with a layer of buffer management that allows updating the digest with any number of bytes. This supersedes the previous implementation in the tree. @franziskuskiefer was kind enough to benchmark the changes: in addition to being verified (thus providing significant safety and security improvements), this implementation also provides a sizeable performance boost! ``` --------------------------------------------------------------- Benchmark Time CPU Iterations --------------------------------------------------------------- Sha2_256_Streaming 3163 ns 3160 ns 219353 // this PR LibTomCrypt_Sha2_256 5057 ns 5056 ns 136234 // library used by Python currently ``` The changes in this PR are as follows: - import the subset of HACL* that covers SHA2-256/224 into `Modules/_hacl` - rewire sha256module.c to use the HACL* implementation Co-authored-by: Gregory P.

* bpo-43974: Move Py_BUILD_CORE_MODULE into module code (GH-29157)Christian Heimes2021-10-221-0/+3
| | | | | | | | | | | | | | setup.py no longer defines Py_BUILD_CORE_MODULE. Instead every module defines the macro before #include "Python.h" unless Py_BUILD_CORE_BUILTIN is already defined. Py_BUILD_CORE_BUILTIN is defined for every module that is built by Modules/Setup. The PR also simplifies Modules/Setup. Makefile and makesetup already define Py_BUILD_CORE_BUILTIN and include Modules/internal for us. Signed-off-by: Christian Heimes <christian@python.org>
* bpo-45434: Remove pystrhex.h header file (GH-28923)Victor Stinner2021-10-131-1/+1
| | | | | | | | | | | | | | | Move Include/pystrhex.h to Include/internal/pycore_strhex.h. The header file only contains private functions.

* bpo-40302: Add pycore_byteswap.h header file (GH-19552)Victor Stinner2020-04-171-13/+4
| | | | | | | | | | | | | | Add a new internal pycore_byteswap.h header file with the following functions: * _Py_bswap16() * _Py_bswap32() * _Py_bswap64() Use these functions in _ctypes, sha256 and sha512 modules, and also use in the UTF-32 encoder. sha256, sha512 and _ctypes modules are now built with the internal C API.
* bpo-40268: Remove unused structmember.h includes (GH-19530)Victor Stinner2020-04-151-1/+1

* bpo-9216: Add usedforsecurity to hashlib constructors (GH-16044)Christian Heimes2019-09-131-4/+8
| | | | | The usedforsecurity keyword only argument added to the hash constructors is useful for FIPS builds and similar restrictive environment with non-technical requirements that legacy algorithms be forbidden by their implementations without being explicitly annotated as not being used for any security related purposes. Linux distros with FIPS support benefit from this being standard rather than making up their own way(s) to do it. Contributed and Signed-off-by: Christian Heimes christian@python.org

| | | | | | | | | | | | | | No detailed change log; just check out the change log for the py3k-pep3137 branch. The most obvious changes: - str8 renamed to bytes (PyString at the C level); - bytes renamed to buffer (PyBytes at the C level); - PyString and PyUnicode are no longer compatible. I.e. we now have an immutable bytes type and a mutable bytes type. The behavior of PyString was modified quite a bit, to make it more bytes-like. Some changes are still on the to-do list.
