PRIVACY & SECURITY

Operational security for issuers, holders, and verifiers. KryptoOS is built fail-closed — ambiguity resolves to "not verified," never "probably fine."

SECURITY GUIDE

FAIL-CLOSED BY DEFAULT

If revocation status cannot be confirmed, verification fails. No silent bypass, no trust-on-first-use shortcuts. Unknown state is treated as untrusted — the safe default for identity systems.

  • Ed25519Signature2020 proofs verified by kryptos-core
  • RFC 8785 tamper-evident canonical JSON
  • On-chain anchor for public trust and revocation state

OPERATIONAL PRACTICES

Production deployments should rotate issuer keys, monitor status list freshness, and keep private keys in HSMs or secure enclaves. Public documentation covers integration patterns without exposing internal infrastructure.

  • Issuer keys: rotate on schedule, publish in DID documents
  • Holder keys: never transmitted to KryptoOS servers
  • Verifier nodes: stateless, horizontally scalable
  • Chain data: DIDs and hashes only — no raw PII
