How to encrypt Lua codes

Question

I want to protect my Lua codes on my project, I'm using Corona SDK.

I saw some lua files being obfuscated like this one

https://github.com/ChartBoost/corona-sdk/blob/master/ChartboostSDK/chartboost.lua

Is there any application to protect my source code?

I want to share a lua sdk on a ads network, but the links are exposed — NaviRamyle, Jul 29 '13 at 03:19

The file you mentioned is not encrypted: it's just precompiled bytecode for Lua 5.1. It can be read with luac -l -p (not in source form but in VM instructions, which are probably enough to reconstruct the source). If you want to reconstruct the source, try LuaDec for Lua 5.1.

You can precompile your code using luac or string.dump.

How do I compile LuaDec? – NaviRamyle Jul 29 '13 at 03:25
I am able to produce luac.out, how can I require it to my project? – NaviRamyle Jul 29 '13 at 04:02
@Ramyle, luac.out can be loaded directly into Lua with `require` or `dofile`. – lhf Jul 29 '13 at 14:40
