Camouflaging Lua Code

[Diabolic]

It may be that someone wants to know how to do, here it is:

lua code:

local script = string.dump(

    function()

        --Content

        print("Camouflaging Done.")



    end

)



buff=""

for v=1,string.len(script) do --Convert our string into a hex string.

    buff=buff..'\\'..string.byte(script,v)

end



file=io.open('encrypted.txt','w') --Output our bytecode into ascii format to encrypted.txt

file:write(buff)

file:flush()

file:close()

Output of example:

\27\76\117\97\81\0\1\4\4\4\8\0\54\0\0\0\64\67\58\92\85\115\101\114\115\92\66\114\117\110\111\92\68\111\99\117\109\101\110\116\115\92\88\101\110\111\66\111\116\92\83\99\114\105\112\116\115\92\101\110\99\114\121\112\116\46\108\117\97\0\2\0\0\0\5\0\0\0\0\0\0\2\4\0\0\0\5\0\0\0\65\64\0\0\28\64\0\1\30\0\128\0\2\0\0\0\4\6\0\0\0\112\114\105\110\116\0\4\19\0\0\0\67\97\109\111\117\102\108\97\103\105\110\103\32\68\111\110\101\46\0\0\0\0\0\4\0\0\0\4\0\0\0\4\0\0\0\4\0\0\0\5\0\0\0\0\0\0\0\0\0\0\0

How to load this ?

Example:

lua code:

local code = '\27\76\117\97\81\0\1\4\4\4\8\0\54\0\0\0\64\67\58\92\85\115\101\114\115\92\66\114\117\110\111\92\68\111\99\117\109\101\110\116\115\92\88\101\110\111\66\111\116\92\83\99\114\105\112\116\115\92\101\110\99\114\121\112\116\46\108\117\97\0\2\0\0\0\5\0\0\0\0\0\0\2\4\0\0\0\5\0\0\0\65\64\0\0\28\64\0\1\30\0\128\0\2\0\0\0\4\6\0\0\0\112\114\105\110\116\0\4\19\0\0\0\67\97\109\111\117\102\108\97\103\105\110\103\32\68\111\110\101\46\0\0\0\0\0\4\0\0\0\4\0\0\0\4\0\0\0\4\0\0\0\5\0\0\0\0\0\0\0\0\0\0\0'



loadstring(code) ()

If anyone has any other way to do this and want to share with people, feel free

It's actually called "obfuscation". Also, anyone can replace the loadstring function with a function that will print out the raw code. It's a nice first step but you can take it much further by using obfuscation around the loader code as well, in ways other than bytecode generation.

You have any example to help ?
I only managed to get up this.

Him putting in here how to do encode would be pretty much equal to explaining people how te decode it.

to encode is not the same thing of decode

Ok, thank you bro

It's interesting. Thx mate

1) You're not encoding. You're not even encrypting. You are obfuscating.
2) If you know the way you are obfuscating, you know how to de-obfuscate.

It's security through obscurity.

I'm not an expert on it, so can I use the SciTE compiler like a method to encrypt my code ?

For example my lib looks like this when I use compile function:



But still can be loaded.

And how to decrypt this code now?
