RSA in Android erzeugt richtige Schlüssel, aber falsche Entschlüsselung

schau dir das mal an

          <?php
             $hashedpassword = crypt("james");

             /*echo $hashedpassword;
            */
           if (password_verify('james', $hashedpassword)) {
              echo 'Password is valid!';
           } else {
              echo 'Invalid password.';
           }
        ?>
