programming three password

[moejo]

Hi just so I don't go too far into writing the code, which I think I might have did, is the $strPassword in function encryptString($strString, $strPassword) the same for all serials? or is the $strPassword unique to each serial.

I am hoping the passwords are the same so I don't have to rewrite alot of my script.
Oh ya, another thing, $strString is the serial and $strPassword is a password? The reason why I ask is because there is a comment saying // $strString is the content of the entire file with serials, which means $strString is not where the serial is placed but a file?
