[ sf.net patch # 1121611 ] A new hashlib module to replace the md5 and sha modules. It adds support for additional secure hashes such as SHA-256 and SHA-512. The hashlib module uses OpenSSL for fast platform optimized implementations of algorithms when available. The old md5 and sha modules still exist as wrappers around hashlib to preserve backwards compatibility.

Have the sha module raise a DeprecationWarning as specified in PEP 4.
