See http://bitop.luajit.org/ http://bitop.luajit.org/ It comes standard as part of LuaJIT, which is likely what should be used for anything like a wireshark plugin (I don't know what wireshark actually uses, but LuaJIT is a drop-in replacement for the most part). Bitop (or something similar) is included in Lua 5.2 as well.
