The MD4 algorithm which produces a 128-bit output from a given input.

Developers should be aware of the negative performance implications of
calling this function multiple times and should consider using
EVP_MD_fetch(3) with EVP_MD-MD4(7) instead.
See ``Performance'' in crypto(7) for further information.
RETURN VALUES
These functions return a EVP_MD structure that contains the
implementation of the message digest. See EVP_MD_meth_new(3) for
details of the EVP_MD structure.
