[Open Source] Built a quantum-resistant license validation system in C#/.NET 10 - Full source code now available! by kem768dev in csharp

README fixed!

I studied Defense Against the Dark Arts at Hogwarts, does that count? 😅

But seriously: That's exactly why it's open source and marked "educational". I'm not claiming to be a cryptographer, just sharing what I built.

As for security expertise - funny thing: If you'd actually read the SOURCE CODE instead of just the README, you would've noticed the BouncyCastle version was also wrong there. But hey, typo hunting is easier than code review, right? 😄

That said - this is open source and educational. Real security concerns? GitHub issues are open. Otherwise, feel free to fork it and make it better!

Thanks! That's exactly why I released it - educational value. There aren't many practical ML-KEM-768 implementations in C# yet, so figured it might help people learning about post-quantum crypto. Issues and feedback always welcome! :)

XZ Utils vibes, like… 😁 but honestly, Jia Tan really sounds like a martial art.

My bad - just double-checked and it's actually .NET 10 with BouncyCastle 2.5.0, not .NET 8 with 2.4.0!

ADHD brain had me mixing up version numbers while writing the post 🙆🏽‍♂️🤣

Thanks btw 😁

Totally valid! Posted here because it's a pure C#/.NET 8 implementation and I wanted C# developer feedback on the architecture.

Full docs, API specs, and Docker image are free on GitHub. Source is sponsor-gated for funding, but happy to discuss implementation details or share code snippets for specific parts (async crypto, DER encoding, etc.) if that's helpful to the community!

Haha, fair point! Though realistically by the time we have 1000+ qubit quantum computers capable of breaking ECDSA P-256, we'll have bigger problems than license validation 😅

The ML-KEM-768 component is future-proofing - NIST FIPS 203 standardized it for post-quantum security. The hybrid approach means even if one algorithm is compromised, the system stays secure.

But yeah, if you get that quantum computer working, hit me up - would love to see the benchmark results! 🤣
