Live Stream VOD: Generic xorstr Decryption (Patreon)
Content
This is a crazy 7h long dev stream! We probably won't do another one of these but if you like you can watch in real time I as build a generic string decryption tool for the xorstr library.
What?
The idea for this tool was developed over the past few streams and I just wanted to test it out. In the end this approach is still fairly brittle, the notes do a better job of explaining all the limitations, but it does work well for the cases we need. Maybe we can call it reverse-taint-yates in honour of Robert Yates who helped immensely during the development process...
In the next stream we will investigate another approach using limited emulation (memulation) which is is less brittle and ultimately is a better approach but also has some limitations.
