Tools
Security Lab
Browser-only crypto tools, experiments, and primitives.
What this is
A personal lab of client-side cryptography, zero-knowledge patterns, and post-quantum primitives. Everything runs locally in your browser.
Faultlines
Deterministic threat model pass
A deterministic first look at where risk concentrates in your system.
Paste
ZeroBin-style encrypted paste
Encrypt text locally and share a self-contained link with the key in the fragment.
Saf
Whole-file encryption
Encrypt and decrypt files locally, producing .saf files with a self-describing format.
FHE Demo
Toy homomorphic addition
See ciphertext addition in action with a tiny Paillier-style demo.
Post-Quantum Crypto
NIST-standardized demos
ML-KEM, ML-DSA, and SLH-DSA demos running locally in your browser.
Privacy
Security model
What the server can see, what it can’t, and the limits of client-side crypto.
