EVP_md5,
EVP_md5_sha1
- MD5 For EVP
=head1 SYNOPSIS
#include <openssl/evp.h>
const EVP_MD *EVP_md5(void);
const EVP_MD *EVP_md5_sha1(void);
=head1 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.
=over 4
=item EVP_md5()
The MD5 algorithm which produces a 128-bit output from a given input.
=item 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.

=head1 RETURN VALUES
These functions return a B<EVP_MD> structure that contains the
implementation of the symmetric cipher. See L<EVP_MD_meth_new(3)> for
details of the B<EVP_MD> structure.
