These files are free to download and use for any purpose, however:
1) Make SURE you change the $securityKeyword and $encryptionKey variables
in "rdSecurity.php" to new secret values of your own.
2) It would be nice to hear a shout out from anyone who finds this useful!
3) If you notice this technique being cracked - that is, if you use these scripts
and your game still winds up on someone elses site, please let me know!
