We’re no longer using our old ftp, rsync, and git links for distributing OpenSSL. These were great in their day, but it’s time to move on to something better and safer. ftp://ftp.openssl.org and rsync://rsync.openssl.org are not available anymore. As of June 1, 2024, we’re also going to shut down https://ftp.openssl.org and git://git.openssl.org/openssl.git mirrors.
GitHub is becoming the main distributor of the OpenSSL releases.
Good that you mention WolfSSL and that HAProxy team seems to like it. Years ago some Linux distributions made the switch to LibreSSL, but unfortunately that all (?) seems to have failed.
