Lua код получает от C кода структурированное представление приходящих пакетов в виде дерева (диссекты), подобного тем, что вы видите в wireshark.
Туда же приходят результаты сборки или дешифровки частей некоторых протоколов (tls, quic).
С код предоставляет функции-хелперы, позволяющие отсылать пакеты, работать с двоичными данными, разбирать TLS, искать маркер-позции и т.д.
С код предоставляет функции-хелперы, позволяющие отсылать пакеты, работать с двоичными данными, разбирать TLS, искать маркер-позиции и т.д.
Имеется библиотека хелперов, написанных на Lua, а так же готовая библиотека программ атаки на DPI (стратегий), реализующая функции *nfqws1* в расширенном варианте
и с большей гибкостью.
