MD4 is specified in RFC1320_ and produces the 128 bit digest of a message.

>>> from Cryptodome.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.
