=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.
