12 const EVP_MD *EVP_md4(void);
16 MD4 is a cryptographic hash function standardized in RFC 1320 and designed by
17 Ronald Rivest, first published in 1990. This implementation is only available
18 with the legacy provider.
24 The MD4 algorithm which produces a 128-bit output from a given input.
30 Developers should be aware of the negative performance implications of
31 calling this function multiple times and should consider using
32 L<EVP_MD_fetch(3)> with L<EVP_MD-MD4(7)> instead.
33 See L<crypto(7)/Performance> for further information.
37 These functions return a B<EVP_MD> structure that contains the
38 implementation of the message digest. See L<EVP_MD_meth_new(3)> for
39 details of the B<EVP_MD> structure.
