+__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'
