: A popular, pure Lua implementation that works with Lua 5.1+ and LuaJIT. local base64 = require("base64") -- Encoding local encoded
: Another widely used script that follows the standard Base64 RFC. Option 3: Built-in Bitwise Solution (Lua 5.3+) : A popular, pure Lua implementation that works with Lua 5
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:
If you are using a modern version of Lua and want a lightweight function without external dependencies, you can use a bitwise-based function found in community snippets on Stack Overflow or GitHub Gists . base64 - LuaRocks
