EVP_MD5(3SSL) OpenSSL EVP_MD5(3SSL)
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.
