Accessing Libera.Chat Via TLS
Libera.Chat provides TLS client access on all servers, on ports 6697, 7000 and 7070. Users connecting over TLS will be given user mode +Z, and is using a secure connection will appear in WHOIS (a 671 numeric).
In order to verify the server certificates on connection, some additional work may be required. First, ensure that your system has an up-to-date set of root CA certificates. On most linux distributions this will be in a package named something like ca-certificates. Many systems install these by default, but some (such as FreeBSD) do not. For FreeBSD, the package is named ca_root_nss, which will install the appropriate root certificates in /usr/local/share/certs/ca-root-nss.crt.
Certificate verification will generally only work when connecting to
libera.chat. If your client thinks the server’s certificate is invalid,
make sure you are connecting to
irc.libera.chat rather than any other name
that leads to Libera.Chat.
For most clients this should be sufficient. If not, you can download the root certificate from LetsEncrypt.
Client TLS certificates are also supported, and may be used for identification to services. For instructions, see our guide on CertFP. If you have connected with a client certificate, has client certificate fingerprint f1ecf46714198533cda14cccc76e5d7114be4195 (showing your certificate’s SHA512 fingerprint in place of f1ecf46…) will appear in WHOIS (a 276 numeric).

PLAIN) mechanisms. See our
guide on setting up CertFP for more information.
Some clients lack SOCKS4a or later support. In this case you will need to

address instead and disable TLS hostname verification in your client. Onion
service names securely identify a service. The connection will still be
The default tor configuration only optimizes some ports for long-lived
connections: For IRC, only
