| 10 | #include <openssl/evp.h> | |
| 11 | ||
| 12 | const EVP_MD *EVP_mdc2(void); | |
| 13 | ||
| 14 | =head1 DESCRIPTION | |
| 15 | ||
| 16 | MDC-2 (Modification Detection Code 2 or Meyer-Schilling) is a cryptographic | |
| 0f6c3ebb SAS |
17 | hash function based on a block cipher. This implementation is only available |
| 18 | with the legacy provider. | |

| 22 | =item EVP_mdc2() | |
| 23 | ||
| 24 | The MDC-2DES algorithm of using MDC-2 with the DES block cipher. It produces a | |
| 25 | 128-bit output from a given input. | |
| 26 | ||

| 29 | =head1 RETURN VALUES | |
| 30 | ||
| 31 | These functions return a B<EVP_MD> structure that contains the | |
| ae2efd63 | 32 | implementation of the message digest. See L<EVP_MD_meth_new(3)> for |
| bbda8ce9 RT |
33 | details of the B<EVP_MD> structure. |
