 const EVP_MD *EVP_md4(void);
MD4 is a cryptographic hash function standardized in RFC 1320 and designed by
  Ronald Rivest, first published in 1990.
  - EVP_md4()
- The MD4 algorithm which produces a 128-bit output from a given input.
These functions return a EVP_MD structure that contains the
  implementation of the symmetric cipher. See EVP_MD_meth_new(3) for
  details of the EVP_MD structure.
