rpki-client 6.7p0 released May 18, 2020
rpki-client is a FREE, easy-to-use implementation of the Resource Public Key Infrastructure (RPKI) for Relying Parties (RP) to facilitate validation of the Route Origin of a BGP announcement. The program queries the RPKI repository system and outputs Validated ROA Payloads in the configuration format of either OpenBGPD or BIRD, but also as CSV or JSON objects for consumption by other routing stacks.
Please refer to RFC 6811 for a description of how BGP Prefix Origin Validation secures the internet's routing infrastructure.
rpki-client was primarily developed by Kristaps Dzonsons, Claudio Jeker, Job Snijders, and Sebastian Benoit as part of the OpenBSD Project and gets released as a base component of OpenBSD every six months.
The portable version, maintained by Sebastian Benoit and Job Snijders, is available via periodic tarball releases. Contributions are welcome to both the rpki-client core and the portable build framework.
The software is freely usable and re-usable by everyone under the ISC license.
