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.
This reverts commit aae5a96d57.
This fix is no longer necessary, our pbkdf2 (see next commit) implementation
no longer rehashes the password every iteration.
* Limit the password length to 4096 bytes
* Password hashers will raise a ValueError
* django.contrib.auth forms will fail validation
* Document in release notes that this is a backwards incompatible change
Thanks to Josh Wright for the report, and Donald Stufft for the patch.
This is a security fix; disclosure to follow shortly.
The _load_library method on BasePasswordHasher turns ImportErrors
into ValueErrors, this masks ImportErrors in the algorithm library.
Changed it to a clearer worded error message that includes
the ImportError string.
* py-bcrypt has not been updated in some time
* py-bcrypt does not support Python3
* py3k-bcrypt, a port of py-bcrypt to python3 is not compatible
with Django
* bcrypt is supported on all versions of Python that Django
supports
