This video tutorial is a detailed walkthrough of hacking a simple Crackme application with the free reverse engineering tool Ghidra recently released by US NSA. In this tutorial, we will:
1) download and unpack an example crachme from crackmes.one
2) understand what the app does and what we must do to break it
3) apply Ghidra to decompile the crackme app
4) examine the decompiled C code to deduce the algorithm
5) find a valid key and validate it
