NativeImage Reverse Engineering

Restoring and protecting Java code is an old and often-discussed issue. Due to the byte-code format used to store Java class files, which contains a lot of meta-information, it can be easily restored to its original code. In order to protect Java code, the industry has adopted many methods, such as obfuscation, bytecode encryption, JNI protection, and so on. However, regardless of the method used, there are still ways and means to crack it.

Binary compilation has always been considered as a relatively effective method of code protection. Java's binary compilation is supported as AOT (Ahead of Time) technology, which means pre-compilation.

However, due to the dynamic nature of the Java language, binary compilation needs to handle issues such as reflection, dynamic proxy, JNI loading, etc., which poses many difficulties. Therefore, for a long time, there has been a lack of a mature, reliable, and adaptable tool for AOT compilation in Java that can be widely applied in p

Raspberry Pi, Static HTTPS site with Docker and Nginx

This tutorial is dated Oct 2021, if it's much further on than that this information might be out of date.

This is a guide on setting up a static HTTPS website on your raspberry pi using docker and nginx. The aim is to have this running on the raspberry pi and to be able to access it from a host computer on the same local network. You should already be able to ssh into your pi from your host computer and have raspberry pi OS set up.

Do not use self-signed certificates in production ! For online certificates, use Let's Encrypt instead (tutorial).
