=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.
