General Information

• All packages are loaded through the Preload() function in preload.go
• Methods are available in Lua as modules: crypto.md5(), encoding.hex_encode(), strings.split(), zlib.compress()
• Decoding methods return two values: result and error (if any)
• Encoding methods return only the result
