Quantum Vault — post-quantum file encryption, in the disc slot.

Quantum Vault
A post-quantum cryptographic file system
Encrypt any file in your browser against the day quantum computers can break today’s public-key crypto. Pick a file, pick a cipher, and Quantum Vault seals it with a post-quantum key exchange — handing you back the only key that opens it.
- Go
- WebAssembly
- ML-KEM (Kyber)
- AES-256-GCM
- ChaCha20-Poly1305
- TypeScript
- Docker
Pick a file
Anything on your machine — it never leaves the browser.
Encapsulate a key
ML-KEM-768 generates the shared secret; you keep the private key.
Seal it
AES-256-GCM or ChaCha20-Poly1305 writes an .encrypted file.
Quantum-resistant by design
ML-KEM (Kyber) is the NIST-standardized post-quantum key encapsulation mechanism — built to hold up against attacks a quantum computer could run against RSA or elliptic-curve keys.
The crypto core is Go, compiled to WebAssembly
Encrypt and decrypt are exposed to the page as WASM functions, so files are sealed and opened client-side. A Go HTTP server delivers the app; a React Router + TypeScript frontend drives it.
You hold the key
Encrypting hands back a private key to store yourself — no key escrow, no accounts, nothing to trust on the server side.
