<p>EVP_MD-MDC2 - The MDC2 EVP_MD implementation</p>
<h1 id="DESCRIPTION">DESCRIPTION</h1>
<p>Support for computing MDC2 digests through the <b>EVP_MD</b> API.</p>
<h2 id="Identity">Identity</h2>
<p>This implementation is only available with the legacy provider, and is identified with the name "MDC2".</p>
<h2 id="Gettable-Parameters">Gettable Parameters</h2>
<p>This implementation supports the common gettable parameters described in <a href="../man7/EVP_MD-common.html">EVP_MD-common(7)</a>.</p>
<h2 id="Settable-Context-Parameters">Settable Context Parameters</h2>
<p>This implementation supports the following <a href="../man3/OSSL_PARAM.html">OSSL_PARAM(3)</a> entries, settable for an <b>EVP_MD_CTX</b> with <a href="../man3/EVP_MD_CTX_set_params.html">EVP_MD_CTX_set_params(3)</a>:</p>
<dl>
<dt id="pad-type-OSSL_DIGEST_PARAM_PAD_TYPE-unsigned-integer">"pad-type" (<b>OSSL_DIGEST_PARAM_PAD_TYPE</b>) <unsigned integer></dt>
<dd>
<p>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.</p>
