Kenny, are you saying you want to implement security *within* your Flex app? I think you'd have serious security holes with that (your decompilation concern, for one). Typically security would be handled at the client-server level, by hosting your SWF on a server that has been configured to a

If your encryption can be broken just because somebody has the source to your algorithm, then it's worthless already =) That's why we've got standard algorithms that rely on keys in the first place. -J On Wed, May 21, 2008 at 2:25 PM, kenny14390 <[EMAIL PROTECTED]> wrote: > So the bottom line

So the bottom line is to use an algorithm like RSA? To take a much simpler example, if the Flex app receives the encrypted data "1234" and it wishes to use that data, it must first decrypt it. So it performs the decryption in some AS and now you have the decrypted data that you wanted. My question

I think you're confusing simple secret key encryption (DES, AES, etc..) with public/private key encryption (RSA). In secret-key encryption if an attacker steals the data and guesses or brute forces the secret key, they can see the data. In public/private key encryption, a message you send to the

Well the concern is that no matter how you choose to encrypt/decrypt information, a Flash movie can always be decompiled and your decryption method is caught with its pants down, allowing users to find out how to view sensitive material that they're not supposed to be looking at.
