Sorry... PHP Screw is a module to encrypt your PHP files so you
don't distribute the source code. It works perfectly in UNIX, but

Just a quick note for people considering using PHP Screw: It is absolutely trivial to decrypt such a file as the encryption algorithm is


datap[i] = (char)pm9screw_mycryptkey[(datalen - i) % cryptkey_len] ^ (~(datap[i]));

See <http://www.schneier.com/crypto-gram-9902.html#snakeoil> for an essay by Bruce Schneier of what he thinks of home-grown crypto :-)
