* bpo-40791: Use CRYPTO_memcmp() for compare_digest (#20456)Christian Heimes2020-05-271-0/+116
| | | | | | | | hashlib.compare_digest uses OpenSSL's CRYPTO_memcmp() function when OpenSSL is available. Note: The _operator module is a builtin module. I don't want to add libcrypto dependency to libpython. Therefore I duplicated the wrapper function and added a copy to _hashopenssl.c.

* bpo-40645: Implement HMAC in C (GH-20129)Christian Heimes2020-05-171-9/+401
| | | | | | | | | The internal module ``_hashlib`` wraps and exposes OpenSSL's HMAC API. The new code will be used in Python 3.10 after the internal implementation details of the pure Python HMAC module are no longer part of the public API. The code is based on a patch by Petr Viktorin for RHEL and Python 3.6. Co-Authored-By: Petr Viktorin <encukou@gmail.com>
* bpo-37630: Use SHA3 and SHAKE XOF from OpenSSL (GH-16049)Christian Heimes2020-05-161-17/+349
| | | | | | | OpenSSL 1.1.1 comes with SHA3 and SHAKE builtin. Signed-off-by: Christian Heimes <christian@python.org> Automerge-Triggered-By: @tiran
* bpo-40515: Require OPENSSL_THREADS (GH-19953)Christian Heimes2020-05-151-0/+4
| | | | | | | The ``ssl`` and ``hashlib`` modules now actively check that OpenSSL is build with thread support. Python 3.7.0 made thread support mandatory and no longer works safely with a no-thread builds. Signed-off-by: Christian Heimes <christian@python.org>
* bpo-40479: Fix hashlib issue with OpenSSL 3.0.0 (GH-20107)Christian Heimes2020-05-151-4/+11
| | | | | | | | | | OpenSSL 3.0.0-alpha2 was released today. The FIPS_mode() function has been deprecated and removed. It no longer makes sense with the new provider and context system in OpenSSL 3.0.0. EVP_default_properties_is_fips_enabled() is good enough for our needs in unit tests. It's an internal API, too. Signed-off-by: Christian Heimes <christian@python.org>
* bpo-9216: Expose OpenSSL FIPS_mode() as _hashlib.get_fips_mode() (GH-19703)Victor Stinner2020-04-291-0/+43
| | | | | | test.pythoninfo logs OpenSSL FIPS_mode() and Linux /proc/sys/crypto/fips_enabled in a new "fips" section. Co-Authored-By: Petr Viktorin <encukou@gmail.com>
* bpo-40268: Remove unused structmember.h includes (GH-19530)Victor Stinner2020-04-151-1/+0
| | | | | | If only offsetof() is needed: include stddef.h instead. When structmember.h is used, add a comment explaining that PyMemberDef is used.

* bpo-38270: More fixes for strict crypto policy (GH-16418)Christian Heimes2019-09-271-1/+1
| | | | | | | | | | | | | | | test_hmac and test_hashlib test built-in hashing implementations and OpenSSL-based hashing implementations. Add more checks to skip OpenSSL implementations when a strict crypto policy is active. Use EVP_DigestInit_ex() instead of EVP_DigestInit() to initialize the EVP context. The EVP_DigestInit() function clears alls flags and breaks usedforsecurity flag again. Signed-off-by: Christian Heimes <christian@python.org> https://bugs.python.org/issue38270
* bpo-38142: Updated _hashopenssl.c to be PEP 384 compliant (#16071)Christian Heimes2019-09-251-54/+68
| | | | * Updated _hashopenssl.c to be PEP 384 compliant * Remove refleak test from test_hashlib. The updated type no longer accepts random arguments to __init__.
* bpo-33936: Don't call obsolete init methods with OpenSSL 1.1.0+ (GH-16140)Christian Heimes2019-09-161-1/+1

* bpo-38153: detect shake independently from sha3 (GH-16143)Christian Heimes2019-09-141-2/+11
| | | | | XOF digests (SHAKE) are not available in OpenSSL 1.1.0 but SHA3 fixed-length digests are. Signed-off-by: Christian Heimes <christian@python.org>
* bpo-37206: Unrepresentable default values no longer represented as None. ↵Serhiy Storchaka2019-09-141-2/+2
| | | | | | | (GH-13933) In ArgumentClinic, value "NULL" should now be used only for unrepresentable default values (like in the optional third parameter of getattr). "None" should be used if None is accepted as argument and passing None has the same effect as not passing the argument at all.

* bpo-9216: Add usedforsecurity to hashlib constructors (GH-16044)Christian Heimes2019-09-131-24/+57
| | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | | * help(hashlib) didn't work because of incorrect module name in blake2b and blake2s classes. * Constructors blake2*(), sha3_*(), shake_*() and keccak_*() incorrectly accepted keyword argument "string" for binary data, but documented as accepting the "data" keyword argument. Now this parameter is positional-only. * Keyword-only parameters in blake2b() and blake2s() were not documented as keyword-only. * Default value for some parameters of blake2b() and blake2s() was None, which is not acceptable value. * The length argument for shake_*.digest() was wrapped out to 32 bits. * The argument for shake_128.digest() and shake_128.hexdigest() was not positional-only as intended. * TypeError messages for incorrect arguments in all constructors sha3_*(), shake_*() and keccak_*() incorrectly referred to sha3_224. Also made the following enhancements: * More accurately specified input and result types for strings, bytes and bytes-like objects. * Unified positional parameter names for update() and constructors. * Improved formatting.

| | | | | | | | | | | kB (*kilo* byte) unit means 1000 bytes, whereas KiB ("kibibyte") means 1024 bytes. KB was misused: replace kB or KB with KiB when appropriate. Same change for MB and GB which become MiB and GiB. Change the output of Tools/iobench/iobench.py. Round also the size of the documentation from 5.5 MB to 5 MiB.
