EVP_md5

NAME

EVP_md5, EVP_md5_sha1 - MD5 For EVP

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 described 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.
