Question

With the following switch case method

switch ($crypt_type) {
      case "MD5": $crypted_pass = md5($password); break;
      case "SHA1": $crypted_pass = sha1($password); break;

      case "DESMD5":
//jpap
//      $salt = substr($crypt_type, 0, 11);
        $salt = substr($p_password, 0, 11);
//jpap
        $crypted_pass = crypt($password, $salt);
        break;

      case "CRYPT":
//jpap
//      $salt = substr($crypt_type, 0, 2);
        $salt = substr($p_password, 0, 2);
//jpap
        $crypted_pass = crypt($password, $salt);
        break;

      default: 
        $crypted_pass = sha1($password); break;
    }

this is the hashed password it was produced

$1$lwnY.pgz$rm4Bwn0XmK7k4QawHi8Cz0

What info can be extracted by this? Is it safe?

Answer 1

Hash function cannot be reversed which is why they are ideal for storing password. For explanation why is that so, check out this SO Question how-come-md5-hash-values-are-not-reversible and see the accepted answer
