[pypy-issue] [issue957] module hashlib is broken for non-standard digest algorithms

[Nirbheek Chauhan]

New submission from Nirbheek Chauhan <nirbheek.chauhan at gmail.com>:

Hash functions supported by openssl which aren't already in the hashlib.py tests
do not work, and either return a blank digest, or raise SIGABRT.

A test case is attached.

* All hashes listed in hashlib.algorithms work fine (these are also in the tests).
* "ripemd160", "md4", "mdc2", "sha" give a blank digest
* "whirlpool" raises SIGABRT, free(): invalid next size (fast)

This is with openssl-1.0.0e, but I don't think it's dependent on that since
these codepaths were never checked by the testsuite in the first place.
