title: Use openssl_encrypt to replace Mcrypt for 3DES-ECB encryption
body: <p>I have an encryption method with mycrypt and the cipher is <code>3des</code>, mode <code>ecb</code>:</p>
  
  <pre><code>mcrypt_module_open ( MCRYPT_3DES, '', 'ecb', '' )
  </code></pre>
  
  <p>Now I want to encrypt it using <code>openssl_encrypt</code>, and I did not find <code>des3-ecb</code> in <code>openssl_get_cipher_methods()</code> list.</p>
