-__doc__ = """hashlib module - A common interface to many hash functions.
-
-new(name, string='') - returns a new hash object implementing the
-                       given hash function; initializing the hash
-                       using the given string data.
-
-Named constructor functions are also available, these are much faster
-than using new():
-
-md5(), sha1(), sha224(), sha256(), sha384(), and sha512()
-
-More algorithms may be available on your platform but the above are
-guaranteed to exist.
-
-NOTE: If you want the adler32 or crc32 hash functions they are available in
-the zlib module.
-
-Choose your hash function wisely.  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'
