EVP_md5(3)                          OpenSSL                         EVP_md5(3)




NAME

       EVP_md5, EVP_md5_sha1 - MD5 For EVP


LIBRARY

       libcrypto, -lcrypto


SYNOPSIS

        #include <openssl/evp.h>

        const EVP_MD *EVP_md5(void);
        const EVP_MD *EVP_md5_sha1(void);


DESCRIPTION

       MD5 is a cryptographic hash function standardized in RFC 1321 and
       designed by Ronald Rivest.

       The CMU Software Engineering Institute considers MD5 unsuitable for
       further use since its security has been severely compromised.

       EVP_md5()
           The MD5 algorithm which produces a 128-bit output from a given
           input.

       EVP_md5_sha1()
           A hash algorithm of SSL v3 that combines MD5 with SHA-1 as decirbed
           in RFC 6101.

           WARNING: this algorithm is not intended for non-SSL usage.


RETURN VALUES

       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.


CONFORMING TO

       IETF RFC 1321.
