hashlib

20081119

Python secure hash and message digest module
MD5, SHA1, SHA224, SHA256, SHA384 and SHA512
(backported from recent Python's for use on 2.3 and 2.4)

DOWNLOADS

hashlib source code: (.tar.gz) or (.zip)

BUILDING

python setup.py build [options]

Valid options: --openssl-prefix=path, --openssl-incdir=path, --openssl-libdir=path

If OpenSSL 0.9.7 or later is found it will be used. Version 0.9.8 is preferred as it provides many more optimized algorithms. OpenSSL is not required.

INSTALLING

python setup.py install

USAGE

Use the following hash object constructors:

md5, sha1, sha224, sha256, sha384, and sha512

Hash objects have update, copy, digest, and hexdigest methods.

    >>> x = hashlib.sha224('spam')
    >>> x.hexdigest()
    'e047c44d875407fdb49d53d8b2326fc3e20e27f08434fef1275a3981'
    >>> y = x.copy()
    >>> y.update(' and eggs')
    >>> y.hexdigest()
    '1c54f569f9b5c7cec6a34465de51df10b0048f3d48f7051ac6eb2e54'
