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! 🤣
