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.
NOTES
Developers should be aware of the negative performance implications of
calling these functions multiple times and should consider using
EVP_MD_fetch(3) with EVP_MD-MD5(7) or EVP_MD-MD5-SHA1(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 1321.
