kipuka

EST enrollment server

A standards-compliant, post-quantum ready certificate enrollment server for private networks. Built in Rust.

kipuka (Hawaiian) — an area of older land surrounded by younger lava flows, an island of stability. Like a kipuka preserves established growth amid change, this server provides stable certificate enrollment amid evolving security requirements.

Built for Private Infrastructure

Everything you need to run a production EST certificate authority on your own terms.

RFC 7030 EST

All six EST operations: cacerts, simpleenroll, simplereenroll, fullcmc, serverkeygen, and csrattrs. Plus STAR auto-renewal (RFC 8739).

Multi-CA & HA

Active-passive, round-robin, weighted, and latency-based failover strategies across multiple certificate authorities.

HSM / PKCS#11

CA private keys loaded from HSMs via PKCS#11. Entrust nShield, Utimaco, Thales Luna, and Kryoptic for dev/test.

Post-Quantum Ready

ML-DSA signing (FIPS 204), ML-KEM key encapsulation (FIPS 203), and composite hybrid algorithms via Synta.

Multi-Database

SQLite for single-node, PostgreSQL or MariaDB for scale. One config line to switch. Automatic migrations.

EAB & Kerberos

mTLS client certificates, one-time passwords with rate limiting, and GSSAPI/Kerberos enterprise SSO integration.


Up and Running in Minutes

Configure, start, and enroll your first certificate.
