hashlib Secure hash and message digest algorithm library Provides the SHA-224, SHA-256, SHA-384, SHA-512 hash algorithms in addition to platform optimized versions of MD5 and SHA1. If OpenSSL is present all of its hash algorithms are provided. This is a stand alone packaging of the hashlib library included with Python 2.5 so that it can be used on older versions of Python (tested on 2.3 and 2.4). Gregory P.
