    basic XOR cipher for gLua
    by Haffy

    The purpose of this is just to serve as an example for people wanting to encrypt data
    using a basic method of encryption known as the XOR cipher (https://en.wikipedia.org/wiki/XOR_cipher)
]]

-- this is the key we're going XOR each character with
local key = 0xA;

local function CipherString(str)
    local new_str = "";
    for i = 1, string.len(str) do
        new_str = new_str .. string.char(bit.bxor(key, string.byte(str[i])));
    end
    return new_str;
end

print(CipherString("hello world!));
