|

| 5 | EVP_MD-MDC2 - The MDC2 EVP_MD implementation
|
|---|
| 6 |
|
|---|
| 7 | =head1 DESCRIPTION
|
|---|
| 8 |
|
|---|
| 9 | Support for computing MDC2 digests through the B<EVP_MD> API.
|
|---|
| 10 |
|
|---|
| 11 | =head2 Identity
|
|---|
| 12 |
|
|---|
| 13 | This implementation is only available with the legacy provider, and is
|
|---|
| 14 | identified with the name "MDC2".
|
|---|
| 15 |
|
|---|
| 16 | =head2 Gettable Parameters
|
|---|
| 17 |
|
|---|
| 18 | This implementation supports the common gettable parameters described
|
|---|
| 19 | in L<EVP_MD-common(7)>.
|
|---|
| 20 |
|
|---|
| 21 | =head2 Settable Context Parameters
|
|---|
| 22 |
|
|---|
| 23 | This implementation supports the following L<OSSL_PARAM(3)> entries,
|
|---|
| 24 | settable for an B<EVP_MD_CTX> with L<EVP_MD_CTX_set_params(3)>:
|
|---|
| 25 |
|
|---|
| 26 | =over 4
|
|---|
| 27 |
|
|---|
| 28 | =item "pad-type" (B<OSSL_DIGEST_PARAM_PAD_TYPE>) <unsigned integer>
|
|---|
| 29 |
|
|---|
| 30 | Sets the padding type to be used.
|
|---|
| 31 | Normally the final MDC2 block is padded with zeros.
|
|---|
| 32 | If the pad type is set to 2 then the final block is padded with 0x80 followed by
|
|---|
| 33 | zeros.
