# 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.
