XiPKI
XiPKI is an open-source public key infrastructure system for certification authority, registration authority, and OCSP responder functions, aimed at critical infrastructure. It supports multiple CAs in one instance, database clusters, and active instances for the same CA, with management through embedded OSGi commands and an API. Its CA gateway supports EST, SCEP, CMP, ACME, and its RESTful API. The OCSP responder handles RFC 2560, RFC 6960, and RFC 5019, along with signed and unsigned requests, health checks, and multiple certificate status sources. HSM connections use PKCS#11; listed devices include AWS CloudHSM, Nitrokey, nCipher, Sansec, SoftHSM, TASS, Thales, and Utimaco. The project describes native support for ML-DSA, ML-KEM, and composite post-quantum algorithms. XiPKI is free under Apache License 2.0. It supports Linux and macOS and requires Java 11 or later and Tomcat 10 or 11. Listed databases include DB2, MariaDB, MySQL, Oracle, PostgreSQL, H2, and HSQLDB.
