gorithm can be obtained by calling:</p>

<pre><code> EVP_PKEY_CTX *pctx = EVP_PKEY_CTX_new_id(EVP_PKEY_RSA_PSS, NULL);</code></pre>

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

<p>All these functions return 1 for success and 0 or a negative value for failure. In particular a return value of -2 indicates the operation is not supported by the public key algorithm.</p>
