MystSafe overview

Quantum-safe security

Ready for the next era of cryptography.

MystSafe combines NIST-standardized post-quantum algorithms with established classical cryptography. Every trusted device creates its own keys, encrypts secret payloads locally, and rejects updates that fail the expected cryptographic checks.

Hybrid by design

Two cryptographic families work together.

Post-quantum and classical protections are both part of the design. Key establishment combines two independent shared-secret paths, while security-sensitive updates must pass both signature paths.

Hybrid key establishment

ML-KEM-768 and ephemeral P-256 ECDH create independent shared secrets. MystSafe combines them and binds the result to the intended vault, devices, object, and purpose.

Hybrid authentication

ML-DSA-65 and ECDSA P-256 sign the same security context. A protected update is accepted only when both signatures and the expected device identities verify.

Authenticated encryption

AES-256-GCM protects secret payloads and wrapped content keys. Fresh nonces and SHA3-256 commitments help bind integrity to the exact protocol content.

More than algorithm names

Quantum readiness is part of the security system—not a badge.

The cryptography is reinforced by per-device keys, strict update verification, and operating-system-protected access.

Keys begin on each device

Every device generates independent encryption and signing identities. Existing private device keys are not copied to a newly paired device.

Context is checked first

Recipients check the expected vault, object, signer, trusted-device state, integrity, and freshness before accepting and decrypting an update.

Local access stays device-bound

Keychain policy and local user presence protect stored key material. Face ID, Touch ID, a device passcode, or macOS authentication authorizes access; biometrics are not used as cryptographic keys.
