Manually editing the configuration files isn't recommended since its kind of complicated. It is recommended to configure using irssi's commands.
-
Start
irssi
and connect to a server. Then enter the commands. -
Auto-connect to a server during startup. Password is server password but can be used as a user password for quick authentication. This method is useful since it authenticates you before irssi tries to connect to the channels, so you are able to join channels where authentication is required. (Password is optional and will be visible in the configuration file in plain text).
/server add -auto -ssl -ssl_verify -ssl_capath /etc/ssl/certs -network freenode irc.freenode.net 6697 password
If you keep getting SSL errors after starting irssi, try removing SSL certificate verification
