title: Can't create a new OpenSSL key
body: <p>I want to learn OpenSSL but I'm just getting <code>boolean false</code> when I am trying to use this code:</p>
  
  <pre><code>$config = array('private_key_bits' =&gt; 512);
  $privKey = openssl_pkey_new($config);
  
  var_dump($privKey);
  </code></pre>
  
  <p>The OpenSSL extension is activated on my server. Have I missed something?</p>
