Master Key Seal/Unseal
orca cluster seal: encrypts master key with OIDC-derived key; prints 5 Shamir shards for offline recovery.orca cluster unseal: operator authenticates via OIDC; master key unwrapped into memory; zeroed on shutdown.orca cluster unseal --recovery: if IdP lost, present 3 of 5 shards.
Master Key Rotation
orca secrets rotate-master [--dry-run]: generates new master key,
re-encrypts all namespace secrets, re-seals. Atomic + automatic rollback.
Incident Response
- Revoke the compromised identity (OIDC user/group or SPIFFE SVID).
- Rotate the master key (
orca secrets rotate-master). - Review the audit log (
orca doctor auditverifies the hash chain). - If the master key is compromised, all historical secrets are compromised (no forward secrecy).
Sudoers Audit
orca doctor proxmox audits the /etc/sudoers.d/orca file against the
expected allowlist (pct + qm with NOEXEC; apt-get/dpkg excluded).
nft Audit
orca doctor nft audits the live nftables ruleset against the emitted one.
