rpki-client-7.3 released

rpki-client 7.3 has just been released and will be available in the
rpki-client directory of any OpenBSD mirror soon.

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 OpenBGPD, BIRD, and also as
CSV or JSON objects for consumption by other routing stacks.

See RFC 6811 for a description of how BGP Prefix Origin Validation
secures the Internet's global routing system.

rpki-client was primarily developed by Kristaps Dzonsons, Claudio
Jeker, Job Snijders, Theo Buehler, Theo de Raadt and Sebastian Benoit
as part of the OpenBSD Project.

This release includes the following changes to the previous release:

 * Improve the HTTP client code (status code handling, http proxy
   support, keep-alive).
 * In RRDP, do not access URI with userinfo (@-sign)
 * Improve RRDP syncing by considering a notification file serial
   jumping backwards as synced repository.
 * Make -R (rsync only) also apply to the fetching of TA files.
 * Only sync *.{cer,crl,gbr,mft,roa} files via rsync and exclude all others.
 * When producing output for OpenBGPd, make use of the 'roa-set
   expires' attribute to prevent machines from loading outdated roa-sets.
 * In RRDP, limit the number of deltas to 300 per repo. If more deltas
   exist, downloading a full snapshot is faster.
 * Limit the validation depth of X509 certificate chains to 12, double
   the current depth seen in RPKI.

rpki-client works on all operating systems with a libcrypto library
based on OpenSSL 1.1 or LibreSSL 3.3, and a libtls library compatible
with LibreSSL 3.3 or later.

rpki-client is known to compile and run on at least the following
operating systems: Alpine, CentOS, Debian, Fedora, FreeBSD, Red Hat,
Rocky, Ubuntu, macOS, and of course OpenBSD!

It is our hope that packagers take interest and help adapt
rpki-client-portable to more distributions.
