Compile and Encrypt Scripts

"You could use loadstring to get a chunk then string.dump and then apply some transformations like cycling the bytes, swapping segments, etc. Transformations must be reversible. Then save to a file.

Note that anyone having access to your "encryptor" Lua module will know how to decrypt your file. If you make your encrypted module in C/C++, anyone with access to source will too, or to binary of Lua encryption module they could require the module too and unofuscate the code. With interpreted language it is quite difficult to do: you can raise the bar a bit via the above the techniques but raising it to require a significant amount of work (the onlybreal deterent) is very difficult AFAIK."
