title: Encrypt decrypt using mcrypt and sha-512?
body: <p>I have gotten a code from php.net. <a href="http://php.net/manual/en/book.mcrypt.php" rel="nofollow">http://php.net/manual/en/book.mcrypt.php</a></p>
  
  <p>Problem is when you encrypt something, the next time the ecrypted one isn't the same as the first one. I need to get the exact same hash using sha512 or sha256. I also need to decrypt it because the function will be used for encrypting customer's name and other data.</p>
  
  <p>Thanks  in advance!</p>
