<p>DSA_generate_key - generate DSA key pair</p>
<h1 id="SYNOPSIS">SYNOPSIS</h1>
<pre><code> #include <openssl/dsa.h>
int DSA_generate_key(DSA *a);</code></pre>
<h1 id="DESCRIPTION">DESCRIPTION</h1>
<p>DSA_generate_key() expects <b>a</b> to contain DSA parameters. It generates a new key pair and stores it in <b>a->pub_key</b> and <b>a->priv_key</b>.</p>
<p>The random generator must be seeded prior to calling DSA_generate_key(). If the automatic seeding or reseeding of the OpenSSL CSPRNG fails due to external circumstances (see <a href="../man7/RAND.html">RAND(7)</a>), the operation will fail.</p>
<h1 id="RETURN-VALUES">RETURN VALUES</h1>
<p>DSA_generate_key() returns 1 on success, 0 otherwise. The error codes can be obtained by <a href="../man3/ERR_get_error.html">ERR_get_error(3)</a>.</p>
