SSL

You can connect to SSL IRC servers :)

Please note you need to find a server that supports SSL, and make sure you are connecting on the correct port for SSL. The way to signify Mibbit should use SSL, is to simply prefix the port with a '+'. For example irc://irc.irchighway.net:+9999 and irc://irc.mozilla.org:+6697

You can also connect to Mibbit.com using SSL. Try it with https://mibbit.com.
