I'm gratified that you think highly enough of Python to ask ;-) A new core `hashlib` module will be included in Python 2.5, but will not be backported to older Python versions. It includes new implementations for SHA-224, -256, -384 and -512. The code and tests are already written, and can be gotten from Python's SVN trunk. python-dev'ers: I failed to find anything in the trunk's NEWS file about this (neither about `hashlib`, nor about any of the specific new hash functions). It's not like it isn't newsworthy ;-) _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
