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.

Repeated calls are equivalent to a single call with the concatenation
of all the arguments. In other words:
>>> m.update(a); m.update(b)
is equivalent to:
>>> m.update(a+b)
:Parameters:
data : byte string/byte array/memoryview
The next chunk of the message being hashed.
