Hi,
MD5 is one way encryption - you can't un-encrypt it, but you can use
it to send a hashed version of your variables between Flash and server,
then you compare hashed variable with one you hash:
//Don't just trust your input like this, you should check it
further earlie
with your flash, in your swf you can send an encrypted key together with the
vote
say you send a string like:
str = MD5.encrypt("userID"+todayDate+someOtherStuff);
and then decode it in PHP
There are MD5 classes for both actionscript and php.
This is not 100% proof. Once the evil doer decom
I got an flash that loads images posted by users, and then anyone can
vote for their favorite, but the problem is that
some people have made an bot running from an proxy to update the php
vote-string, wich means I cant trace their ip and
then narrow it down to one vote per picture per ip.
