High-grade. Local-first. Post-quantum ready. Forever free.
A complete .NET 8 security framework built for real-world apps — from password managers to distributed systems.
Built with BouncyCastle, Konscious Argon2, and battle-tested in the fires of XRUIOS, Project Replicant, and Database Designer.
Now yours to wield.
