Encrypting as3 flash .swf

Question

I\'m trying to protect my as3 .swf flash file code from decompilation. I cannot spend $$$ on commercial compilers though. How can i encrypt my swf for free?

As others in this thread have said, I honestly wouldn't waste your time; even if you were to shell out for SecureSWF; you can only really achieve obfuscation rather than full encryption as the bytecode has to be loaded into memory in order to execute in the flash player (and can therefore be dumped out).

If you want to read more about the subject (and indeed, learn more about how to get around common SWF encryption techniques) then I'd suggest spending some time on Jean-Philippe Auclair's blog, especially the articles in the security category.
