hardburn "SSL won't save you here.The user can still modify the parameters being passed on their end."

Sorry, but I didn't get the part where the user shouldn't be allowed to change parameters. I figured the OP wanted a way to make sure the sensative data couldn't be snooped by others. Using SSL seems valid in this case, if you'd ask me. But please explain.

And yes ... I should have suggested using the post method over the get method too.
