Some have known collision weaknesses. -sha384 and sha512 will be slow on 32 bit platforms. - -Hash objects have these methods: - - update(arg): Update the hash object with the string arg. Repeated calls - are equivalent to a single call with the concatenation of all - the arguments. - - digest(): Return the digest of the strings passed to the update() method - so far. This may contain non-ASCII characters, including - NUL bytes. - - hexdigest(): Like digest() except the digest is returned as a string of - double length, containing only hexadecimal digits. - - copy(): Return a copy (clone) of the hash object. This can be used to - efficiently compute the digests of strings that share a common - initial substring. - -For example, to obtain the digest of the string 'Nobody inspects the -spammish repetition': - - >>> import hashlib - >>> m = hashlib.md5() - >>> m.update("Nobody inspects") - >>> m.update(" the spammish repetition") - >>> m.digest() - '\\xbbd\\x9c\\x83\\xdd\\x1e\\xa5\\xc9\\xd9\\xde\\xc9\\xa1\\x8d\\xf0\\xff\\xe9' - -More condensed: - - >>> hashlib.sha224("Nobody inspects the spammish repetition").hexdigest() - 'a4337bc45a8fc544c03f52dc550cd6e1e87021bc896588bd79e901e2' - -""" - -# This tuple and __get_builtin_constructor() must be modified if a new -# always available algorithm is added. -__always_supported = ('md5', 'sha1', 'sha224', 'sha256', 'sha384', 'sha512') - -algorithms = __always_supported - -__all__ = __always_supported + ('new', 'algorithms') - - -def __get_builtin_constructor(name): - try: - if name in ('SHA1', 'sha1'): - import _sha - return _sha.new - elif name in ('MD5', 'md5'): - import _md5 - return _md5.new - elif name in ('SHA256', 'sha256', 'SHA224', 'sha224'): - import _sha256 - bs = name[3:] - if bs == '256': - return _sha256.sha256 - elif bs == '224': - return _sha256.sha224 - elif name in ('SHA512', 'sha512', 'SHA384', 'sha384'): - import _sha512 - bs = name[3:] - if bs == '512': - return _sha512.sha512 - elif bs == '384': - return _sha512.sha384 - except ImportError: - pass # no extension module, this hash is unsupported. - - raise ValueError('unsupported hash type %s' % name) - - -def __get_openssl_constructor(name): - try: - f = getattr(_hashlib, 'openssl_' + name) - # Allow the C module to raise ValueError.
