PHP - Has anyway to encrypt/decrpyt hash in PHP? : <p>I'm interested to encrypt/decrpyt hash in PHP.</p>

<p>But as I know hash can be encoding only with md5, sha1, sha256.</p>

<p>However, is it possible to make encrypt/decrpyt in PHP by another hash like ripemd160, haval256,5 or ripemd256?</p>

<p>Thank</p>
