| =head1 NAME |
| |
| EVP_MD-MDC2 - The MDC2 EVP_MD implementation |
| |
| =head1 DESCRIPTION |
| |
| Support for computing MDC2 digests through the B<EVP_MD> API. |
| |
| =head2 Identity |
| |
| This implementation is only available with the legacy provider, and is |
| identified with the name "MDC2". |
| |
| =head2 Gettable Parameters |
| |
| This implementation supports the common gettable parameters described |
| in L<EVP_MD-common(7)>. |
| |
| =head2 Settable Context Parameters |
| |
| This implementation supports the following L<OSSL_PARAM(3)> entries, |
| settable for an B<EVP_MD_CTX> with L<EVP_MD_CTX_set_params(3)>: |
| |
| =over 4 |
| |
| =item "pad-type" (B<OSSL_DIGEST_PARAM_PAD_TYPE>) <unsigned integer> |
| |
| Sets the padding type to be used. |
| Normally the final MDC2 block is padded with zeros. |
| If the pad type is set to 2 then the final block is padded with 0x80 followed by |
| zeros. |
