[Solved] How to remove mcrypt functions in php

by


Finally I got the solution – thank you all for your help and support by pushing me into the right direction and asking the right questions. The main thing I missed was ECB-Mode (I took CBC…). So all the stuff with the $iv wasn’t really needed.

To complete the answer here my new functions:

function _encrypt_openssl($cleartext, $key = "th1s1sav3rys3cr3tk3y") {
   if ($m = strlen($cleartext) %8) {
      $cleartext .= str_repeat("\0", 8-$m);
   } 
   $encrypted_openssl = openssl_encrypt($cleartext , "DES-EDE3-ECB", $key, OPENSSL_RAW_DATA | OPENSSL_NO_PADDING, null);
   return bin2hex($encrypted_openssl);
}

function _decrypt_openssl($crypttext, $key = "th1s1sav3rys3cr3tk3y") {
   return openssl_decrypt(hex2bin($crypttext), 'DES-EDE3-ECB', $key, OPENSSL_RAW_DATA | OPENSSL_NO_PADDING, null);
}
