+
+new(name, data=b'', **kwargs) - returns a new hash object implementing the
+                                given hash function; initializing the hash
+                                using the given binary data.
+
+Named constructor functions are also available, these are faster
+than using new(name):
+
+md5(), sha1(), sha224(), sha256(), sha384(), sha512(), blake2b(), blake2s(),
+sha3_224, sha3_256, sha3_384, sha3_512, shake_128, and shake_256.
+
+More algorithms may be available on your platform but the above are guaranteed
+to exist.  See the algorithms_guaranteed and algorithms_available attributes
+to find out what algorithm names can be passed to new().
+
+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(data): Update the hash object with the bytes in data. Repeated calls
+                 are equivalent to a single call with the concatenation of all
+                 the arguments.
+ - digest():     Return the digest of the bytes passed to the update() method
+                 so far as a bytes object.
+ - 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 datas that share a common
+                 initial substring.
+
+For example, to obtain the digest of the byte string 'Nobody inspects the
+spammish repetition':
+
+    >>> import hashlib
+    >>> m = hashlib.md5()
+    >>> m.update(b"Nobody inspects")
+    >>> m.update(b" the spammish repetition")
+    >>> m.digest()
+    b'\\xbbd\\x9c\\x83\\xdd\\x1e\\xa5\\xc9\\xd9\\xde\\xc9\\xa1\\x8d\\xf0\\xff\\xe9'
+
+More condensed:
+
+    >>> hashlib.sha224(b"Nobody inspects the spammish repetition").hexdigest()
+    'a4337bc45a8fc544c03f52dc550cd6e1e87021bc896588bd79e901e2'
