OpenXPKI is an enterprise-grade PKI/Trustcenter software. It implements the necessary features to operate a PKI in professional environments. While primarily designed to run as an online RA/CA for managing X509v3 certificates, its flexibility allow for a wide range of possible use cases with regard to cryptographic key management.
OpenXPKI has a stable, mature code base and a growing user base. The developer team actively supports several professional installations some of which have been running continuously since 2009 and host several logical CAs with hundreds of thousands of active certificates.
Version 2.0 is available as of May 2018.
Packages for Debian Jessie are available on the package mirror, see the quickstart for installation details. The product is actively maintained, new packages are published several times a year and announced via the mailing lists.
Enterprise support and professional services are available from White Rabbit Security GmbH, Germany.
