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.
