toKaos is a desktop software application which allows you to encrypt/obfuscate your action script AS3 source code.
toKaos is the only product able to operate directly on a copy of your source code providing you with a new encrypted/obfuscated source code. After the process you can compile and deploy your product (SWF or SWC).
Having the encrypted/obfuscated source code available is a more powerful tool than having only an encrypted SWF/SWC, because you have a total control of the software that you are deploying. Furthermore you will be able to verify what the SWF/SWC source hacker will be able to see.
