Real end-to-end encryption — with a way back in.
VESvault gives developers true end-to-end encryption and a realistic recovery path after a lost device — without the service ever being able to read your keys or your data. New keys are post-quantum by default (ML-KEM / FIPS 203).
- Zero-knowledge server. It stores only public keys, encrypted private keys, and encrypted vault entries. It never sees a VESkey or a decrypted private key — every decryption happens client-side.
- Recovery without a backdoor. Total device loss is handled by threshold
secret sharing among recovery contacts you choose in advance (Shamir over
GF(256), scheme
SSS1). No single party — and no coalition of contacts — can recover your keys alone: each share is stored encrypted to its contact's key, so the server can't read any share; contacts never receive your encrypted keys; and recovery is time-delay protected and visible to the owner. - Open source. The client libraries and the
vesCLI are Apache-2.0.
