-"""MD4 cryptographic hash algorithm.
-
-MD4 is specified in RFC1320_ and produces the 128 bit digest of a message.
-
- >>> from Crypto.Hash import MD4
- >>>
- >>> h = MD4.new()
- >>> h.update(b'Hello')
- >>> print h.hexdigest()
-
-MD4 stand for Message Digest version 4, and it was invented by Rivest in 1990.
-
-This algorithm is insecure. Do not use it for new designs.
