AdwanceSNI
The original tool that started the series — a simple, advanced SNI finding utility for network reconnaissance.
What it is
AdwanceSNI scans for SNI-capable hosts that can be used for testing and research. It is the first version of the tool — minimal, scriptable and easy to run anywhere Python runs.
Highlights
- SNI host finding
- Simple command-line usage
- Lightweight — runs anywhere Python runs
- Basis for AdwanceSNI 2.0
Why I built it
This started as a personal utility for my own recon work. It grew popular enough on GitHub that it earned a bigger successor, but the original stays up because it is simple and it works.
Tech stack
Built with Python, Security. The complete source code is open on GitHub at github.com/SirYadav1/AdwanceSNI — clone it, read it, fork it, and open issues if something breaks.
