And is there a random serial number generator out there? Do they HAVE to be as long as the Rev serial numbers?
No, it doesn't have to be as long. It includes embedded info and I would guess it is double what it might be even then.
Here is a very short verification code generator (off the top of my head):
-- keep this secret somehow and share it between the product and generator
local secret = "John Tenny's Blaster 4000 LE"
function verificationCode userEmailAddress return char 1 to 5 of base64Encode(md5digest(userEmailAddress&secret)) end verificationCode
function isValidCode userEmailAddress code set caseSensitive to true return code = verificationCode(userEmailAddress) end isValidCode
Gotta run; you may need to repair this.
