Do you want to protect your SWF work from being stolen? Anyone can decompile your flash work, change and distribute it as its own.

Will SwfShield protect my SWF Resources (Images, Sounds etc)?

Yes. Unlike other SWF protectors SwfShield will encrypt ALL internal SWF resources.

What is the idea of SwfShield encryption method?

SwfShield uses new capabilities of the Flash Player 9. SwfShield encrypts the original SWF file and embeds it into the new SWF file. This procedure is repeated a few times with different encryption parameters.

Are Encrypted SWF Files 100% Secure?

It is theoretically impossible to formulate a 100% secure solution to prevent reverse engineering of SWF files. However, SwfShield uses new, multilayer encryption algorithm that provides extremely efficient encryption of SWF files. Multilayer encryption algorithm protects SWF file against automatic decompilation. Malice should manually extract and encrypt layer by layer before he gets the source.

Can I protect SWF file against illegal copying or distribution?
