NAME

6       EVP_md5, EVP_md5_sha1 - MD5 For EVP
7

SYNOPSIS

9        #include <openssl/evp.h>
10
11        const EVP_MD *EVP_md5(void);
12        const EVP_MD *EVP_md5_sha1(void);

DESCRIPTION

15       MD5 is a cryptographic hash function standardized in RFC 1321 and
16       designed by Ronald Rivest.
17
18       The CMU Software Engineering Institute considers MD5 unsuitable for
19       further use since its security has been severely compromised.
20
21       EVP_md5()
22           The MD5 algorithm which produces a 128-bit output from a given
23           input.
24
25       EVP_md5_sha1()
26           A hash algorithm of SSL v3 that combines MD5 with SHA-1 as
27           described in RFC 6101.
28
29           WARNING: this algorithm is not intended for non-SSL usage.

RETURN VALUES

32       These functions return a EVP_MD structure that contains the
33       implementation of the symmetric cipher. See EVP_MD_meth_new(3) for
34       details of the EVP_MD structure.
35

CONFORMING TO

37       IETF RFC 1321.
