<p>EVP_md2 - MD2 For EVP</p>

<h1 id="SYNOPSIS">SYNOPSIS</h1>

<pre><code>#include &lt;openssl/evp.h&gt;

const EVP_MD *EVP_md2(void);</code></pre>

<h1 id="DESCRIPTION">DESCRIPTION</h1>

<p>MD2 is a cryptographic hash function standardized in RFC 1319 and designed by Ronald Rivest. This implementation is only available with the legacy provider.</p>

<dl>

<dt id="EVP_md2">EVP_md2()</dt>
<dd>

<p>The MD2 algorithm which produces a 128-bit output from a given input.</p>

</dd>
</dl>

<h1 id="NOTES">NOTES</h1>

<p>Developers should be aware of the negative performance implications of calling this function multiple times and should consider using <a href="../man3/EVP_MD_fetch.html">EVP_MD_fetch(3)</a> with <a href="../man7/EVP_MD-MD2.html">EVP_MD-MD2(7)</a> instead. See <a href="../man7/crypto.html">&quot;Performance&quot; in crypto(7)</a> for further information.</p>

<h1 id="RETURN-VALUES">RETURN VALUES</h1>

<p>These functions return a <b>EVP_MD</b> structure that contains the implementation of the message digest. See <a href="../man3/EVP_MD_meth_new.html">EVP_MD_meth_new(3)</a> for details of the <b>EVP_MD</b> structure.</p>
