"""MD2 cryptographic hash algorithm.

MD2 is specified in RFC1319_ and it produces the 128 bit digest of a message.

>>> from Crypto.Hash import MD2
    >>>
    >>> h = MD2.new()
    >>> h.update(b'Hello')
    >>> print h.hexdigest()

MD2 stand for Message Digest version 2, and it was invented by Rivest in 1989.

This algorithm is both slow and insecure. Do not use it for new designs.
