The logical XOR can be used for encrypting data. Use resource A as your original text and resource B as the key. Be sure to use long enough key so that the key doesn't loop. Decryption works the same way, input encrypted text as res A and key as res B. -- http://www.php.net/manual/en/function.gmp-xor.php http://master.php.net/manage/user-notes.php?action=edit+23298 http://master.php.net/manage/user-notes.php?action=delete+23298 http://master.php.net/manage/user-notes.php?action=reject+23298
