NAME
       EVP_MD-MDC2 - The MDC2 EVP_MD implementation

DESCRIPTION
       Support for computing MDC2 digests through the EVP_MD API.

   Identity
       This implementation is only available with the legacy provider, and is identified with the
       name "MDC2".

   Gettable Parameters
       This implementation supports the common gettable parameters described in EVP_MD-common(7).

   Settable Context Parameters
       This implementation supports the following OSSL_PARAM(3) entries, settable for an EVP_MD_CTX
       with EVP_MD_CTX_set_params(3):

       "pad-type" (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.
