14=head1 DESCRIPTION
15
16MDC-2 (Modification Detection Code 2 or Meyer-Schilling) is a cryptographic
17hash function based on a block cipher. This implementation is only available
18with the legacy provider.

23
24The MDC-2DES algorithm of using MDC-2 with the DES block cipher. It produces a
25128-bit output from a given input.

31These functions return a B<EVP_MD> structure that contains the
32implementation of the symmetric cipher. See L<EVP_MD_meth_new(3)> for
33details of the B<EVP_MD> structure.
