The most reliable way to get a Base64 library is through the LuaRocks repository . Open your terminal and run: luarocks install base64 Once installed, you can use it in your script like this:

: A popular, pure Lua implementation that works with Lua 5.1+ and LuaJIT.

If you cannot use LuaRocks, you can download a single-file implementation and include it directly in your project folder.

: Another widely used script that follows the standard Base64 RFC. Option 3: Built-in Bitwise Solution (Lua 5.3+)
