KeyTalk CKMS vs XiPKI

KeyTalk CKMS automates PKI implementation and the enrollment, distribution and management of digital certificates. It keeps certificates and keys in a central repository and supports automated or semi-automated deployment and renewal, alongside reporting, notifications and alerts. Smart Security Scan finds certificates and keys on a network so valid findings can be imported. The product includes a private certificate authority that can operate beneath an existing root or as a standalone root. Integrations and protocols include DigiCert, DigiCert QuoVadis, GlobalSign, Microsoft CA, Intune, MobileIron, load balancers, HSMs, Citrix, SCEP and ACME. Access controls include AD and Entra ID authorization, multifactor authentication and role-based controls. CKMS can run as a virtual machine on customer infrastructure, in private cloud environments such as AWS, Azure and Google Cloud, or as KeyTalk-managed PKI service. General CKMS pricing is on request, and a free trial is available. Separate S/MIME plans cost €5 a month for on-premise service and €6.50 a month for hosted SaaS, billed per user per month.

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.
