PQC SDKPost-quantum cryptography for JS/TS

X-Wing hybrid (X25519 + ML-KEM-768) by default, ML-KEM-768 and ML-DSA-65 (FIPS 203/204) when you need them. An API you can adopt in 30 minutes — key management and interop are still yours to design.

Why PQC now?

🔐

Zero-config

pqc.encrypt and you're done. Safe defaults chosen for you — the one decision worth making, hybrid vs pure ML-KEM, is documented rather than hidden.

🌍

Runs everywhere

Node 20+, Cloudflare Workers, Deno and React Native — each verified by running the roundtrip there. No WASM, no native addons; ~26-28 KB gzip bundled, depending on what you import.

✅

Verified, and specific about how

Official NIST ACVP vectors, golden wire-format vectors, parser fuzzing, property tests and a streaming mutation matrix — each one a file you can read.

"Hybrid ML-KEM-768 + AES-256-GCM" above means the KEM-DEM construction — a post-quantum KEM wrapping a symmetric cipher — not a classical+post-quantum hybrid. Two senses of "hybrid" →
