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