Hey Everyone,

I was just wondering if anyone had any advice on protecting an SWF from download and decompilation. I’ve read about the pre-loader/encryption method, but I realize that it someone decompiles your pre-loader, they have access to your encryption method, and can reverse-engineer it.

Has anyone found any other fairly successful methods?

Thanks!
