Encrypt.dll

Download Latest Version

Encrypt is a closed library which allows encrypted saving of data.

Unlike the Data class, you can only save numbers to encrypted data files.

Requires bitwise.lua

Installation

Place the file encrypt.dll into the LuaScriptsLib folder.

How to use

To enable the Encrypt library for a specific level, add this line to lunadll.lua:

local encrypt = loadAPI("encrypt");

This will load the Encrypt API.

Example

local encrypt = loadAPI("encrypt");
    
--Defines a new encrypted data file
local edata = encrypt.Data(Data.DATA_LEVEL, "encryptedData", true);

function onLoad()
    edata:set("myVar", 1);
    edata:save();
end

function onLoop()
    printText(tostring(edata:get("myVar")),3,0,0);
end

This will save the value 1 to the variable myVar, as with the Data class, but will encrypt the data so it cannot be easily edited from the resulting text file.
