Here's a quick guide for those using irssi.

First you'll need to generate an ssl certificate, like so:

cd ~/.irssi/
mkdir certs
cd certs
openssl req -nodes -newkey rsa:2048 -keyout Rizon.key -x509 -days 365 -out Rizon.cer

answer the questions and then run the following command:

cat Rizon.crt Rizon.key > Rizon.pem

now open up and run the following command:

/server add -auto -ssl -ssl_cert ~/.irssi/certs/Rizon.pem -network Rizon irc.rizon.net 6697

you can now connect using /connect Rizon

To change your default nick, open ~/.irssi/config and change the nick value in the "settings" section at the bottom.
open up irssi again, and you should connect to Rizon automatically. You can now register your nick using the normal nickserv commands and connect to #janiteam as usual.

however, for the trouble of generating your own ssl certificate, you get the added benefit of not having to identify to nickserv each session. Connect to Rizon and run the following commands:

/msg nickserv identify [your password]
/msg nickserv access add fingerprint

now your nick should auto-identify whenever you fire up irssi.
finally, to configure irssi to auto-join #janiteam:

/channel add -auto #janiteam Rizon [current password]

if you're not familiar with irssi, note that this will connect to the channel in a separate window, not the main one. You can access it with:

/win 2

you can change #janiteam to the main window by messing with the layout, but I won't get into that here.
