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>
