Quoting JulianG <[EMAIL PROTECTED]>:
Hello:
I'm developing a small flash game for a website.
Users must register and log-in before they're allowed to post their
scores to the back-end.
Nevertheless I don't want to have the scores posted in a simple way,
because someone could easily, sign up, log-in, and then post a higher
score without even playing the game.
My idea is to encrypt the score using some algorithm in ActionScript,
something that I can reproduce in PHP on the server side.
I don't want them to be able to read an encrypted score and then try
similar strings in order to get a higher score by chance. I think the
encrypted string should have a check digit or character or something so
it auto-validates.
Do you know of anywhere I could start reading?
or perhaps get an encryption algorithm that I can use?
I use MD5 on my stuff at www.thecodezone.com (which sounds similar to
what you're trying to do, give it a try). MD5 is built into PHP, so
that's easy. A quick google-search will find you a couple of
Actionscript and/or Javascript implementations.
