2021-10-12Fixed #28401 -- Allowed hashlib.md5() calls to work with FIPS kernels.Ade Lee
md5 is not an approved algorithm in FIPS mode, and trying to instantiate a hashlib.md5() will fail when the system is running in FIPS mode. md5 is allowed when in a non-security context. There is a plan to add a keyword parameter (usedforsecurity) to hashlib.md5() to annotate whether or not the instance is being used in a security context. In the case where it is not, the instantiation of md5 will be allowed. See https://bugs.python.org/issue9216 for more details. Some downstream python versions already support this parameter. To support these versions, a new encapsulation of md5() has been added. This encapsulation will pass through the usedforsecurity parameter in the case where the parameter is supported, and strip it if it is not.

2014-07-11Bump the default iterations for PBKDF2.Alex Gaynor
The rate at which we've increased this has not been keeping up with hardware (and software) improvements, and we're now considerably behind where we should be. The delta between our performance and an optimized implementation's performance prevents us from improving that further, but hopefully once Python 2.7.8 and 3.4+ get into more hands we can more aggressively increase this number.
2014-05-31Note that the stdlib's version of pbkdf2_hmac will also be used in the ↵Alex Gaynor
upcoming Python 2.7.8 release
2014-05-28Fixed constant_time_compare on Python 2.7.7Florian Apolloner
Python 2.7.7 includes compare_digest in the hmac module, but it requires both arguments to have the same type. This is usually not a problem on Python 3 since everything is text, but we have mixed unicode and str on Python 2 -- hence make sure everything is bytes before feeding it into compare_digest.

2014-04-17Typo fixAlex Gaynor
2014-04-17Use the stdlib's PBKDF2 implementation when available.Alex Gaynor
This is a bit faster than ours, which is good, because it lets you increase the iteration counts. This will be used on Python 3.4+, and, pending the acceptance of PEP466, on newer Python 2.7s.

2013-09-19Increase default PBKDF2 iterationsPaul McMillan
Increases the default PBKDF2 iterations, since computers have gotten faster since 2011. In the future, we plan to increment by 10% per major version.

In all those occurrences, we didn't care about preserving the lazy status of the strings, but we really wanted to obtain a real bytestring.

2012-08-07[py3] Ported django.utils.encoding.Aymeric Augustin
* Renamed smart_unicode to smart_text (but kept the old name under Python 2 for backwards compatibility). * Renamed smart_str to smart_bytes. * Re-introduced smart_str as an alias for smart_text under Python 3 and smart_bytes under Python 2 (which is backwards compatible). Thus smart_str always returns a str objects. * Used the new smart_str in a few places where both Python 2 and 3 want a str.
