EVP_md4(3)                          OpenSSL                         EVP_md4(3)



NAME
       EVP_md4 - MD4 For EVP

LIBRARY
       libcrypto, -lcrypto

SYNOPSIS
        #include <openssl/evp.h>

        const EVP_MD *EVP_md4(void);

DESCRIPTION
       MD4 is a cryptographic hash function standardized in RFC 1320 and
       designed by Ronald Rivest, first published in 1990. This implementation
       is only available with the legacy provider.

       EVP_md4()
           The MD4 algorithm which produces a 128-bit output from a given
           input.

NOTES
       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.

CONFORMING TO
       IETF RFC 1320.
