mopac-keyproxy
A key-material proxy where the vault stays authoritative. Consumers receive opaque placeholder keys; real secrets live only in Bitwarden Secrets Manager and/or HashiCorp Vault and are resolved to real material at the wire, in memory, never persisted, with no admin UI to attack.
- Placeholders in, real keys on the wire out (
mpk_...refs; a leaked placeholder is revoke-and-remap, not an incident). - Backends: Bitwarden Secrets Manager REST (machine accounts) and HashiCorp Vault KV v2 + AppRole. Stdlib-first; no Bitwarden SDK (license).
- Serves as both an HTTP hop and a CLI (
keyproxy get <ref>for exec-style plumbing). - AGPLv3. Part of the MOPAC family but standalone and composable: generic, config-driven, no organizational assumptions baked into code.
Status: specification phase (see MOPAC/harness/DESIGN.md, "Key proxy"). Building 2026-08-28 onward.
