| |
| EVP_mdc2 |
| - MDC-2 For EVP |
| |
| =head1 SYNOPSIS |
| |
| #include <openssl/evp.h> |
| |
| const EVP_MD *EVP_mdc2(void); |
| |
| =head1 DESCRIPTION |
| |
| MDC-2 (Modification Detection Code 2 or Meyer-Schilling) is a cryptographic |
| hash function based on a block cipher. This implementation is only available |
| with the legacy provider. |
| |
| =over 4 |
| |
| =item EVP_mdc2() |
| |
| The MDC-2DES algorithm of using MDC-2 with the DES block cipher. It produces a |
| 128-bit output from a given input. |
| |
| =back |
| |
| =head1 RETURN VALUES |
| |
| These functions return a B<EVP_MD> structure that contains the |
| implementation of the message digest. See L<EVP_MD_meth_new(3)> for |
| details of the B<EVP_MD> structure. |
| |
| =head1 CONFORMING TO |
| |
| ISO/IEC 10118-2:2000 Hash-Function 2, with DES as the underlying block cipher. |
