Show HN: Cifer, zero-key custody using threshold cryptography

Cifer, zero-key custody using threshold cryptography is a business in show hn launch.

Profile

I built CIFER, a distributed encryption + access-control system designed so that no component ever holds a complete decryption key at rest.Core idea: each “secret” (per user or per dataset) has its own independent post-quantum keypair. There is no master key.Architecture summary:Control plane: verifiable ownership, delegation, revocation, and append-only audit records (tamper-evident authorization history)Custody plane: 5 custody nodes running in TEEs, each storing 1 key fragmentOrchestration: validates authorization then collects fragments to reconstruct keys only when neededKey custody model:Private key is generated in a TEE then immediately split via Shamir secret sharing into 5 fragments

Within the show hn launch space, the company focuses on its core offering rather than a broad product line.

The company is listed at the Show HN launch stage of development.
