 Set up your ~/.irssi/config with
 {{{
 servers = (
   {
     address = "irc.oftc.net";
     chatnet = "oftc";
     #port = "6667";
     port = "6697";
     use_ssl = "yes";
     # ssl_cert = "~/.irssi/certs/[NICK].pem";
     # ssl_verify = "yes";
     # ssl_cafile = "~/.irssi/certs/CAs.pem";
     autoconnect = "yes";
   }
 );
 }}}

 and then run
 {{{
 usewithtor irssi
 }}}

 Your Tor client will log something like
 {{{
 Jan 27 17:43:52.000 [warn] Socks version 22 not recognized. (Tor is not an
 http proxy.)
 Jan 27 17:43:52.000 [warn] Fetching socks handshake failed. Closing.
 }}}

 and your irssi will complain with something like
 {{{
 18:06 -!- Irssi: Looking up irc.oftc.net
 18:06 -!- Irssi: Connecting to irc.oftc.net [140.211.166.64] port 6697
 18:06 -!- Irssi: warning SSL handshake failed: Connection reset by peer
 18:06 -!- Irssi: Connection lost to irc.oftc.net
 }}}

 What's happening behind the scenes is that your irssi is attempting a
 connect, getting an einprogress (presumably since it's non-blocking),
 sending the ssl handshake right then, and then later torsocks tries to
 inject the socks handshake. Oops.
