*IRC over TLS is not pointless unless you only worry about things that you
|
|
cannot affect at all. SSL is pointless, because of [POODLE].*
|
|
|
|
I use IRC over TLS on all networks that support it (=other than IRCnet)
|
|
and I also [verify the certificates]. TLS is used
|
|
|
|
*Update on 2015-06-18: I was told that IRCnet does have SSL on
|
|
ssl.irc.atw-inter.net and ssl.rfc1459.ca, but server links are mostly
|
|
unencrypted. I am not able to use those though as Finnish channels are
|
|
mostly stupid and letting people only in from Finnish servers.*
|
|
|
|
* between my client and bouncer
|
|
* when they both are on localhost it's not used and my bouncer only
|
|
listens for plain text connections only on `127.0.0.1` and `::1`.
|
|
* between my bouncer and IRCd
|
|
|
|
These are the points that I can affect. I cannot do anything to server
|
|
links other than hope that the network operators know what they are doing
|
|
and use TLS. I cannot affect whether other users use TLS or not or do they
|
|
check the certificates or blindly accept whatever they are offered.
|
|
|
|
As I use TLS everywhere where I can affect, I can be more sure that
|
|
my discussions aren't so easily read on:
|
|
|
|
* open WLAN
|
|
* any router between me and the bouncer
|
|
* any router between bouncer and the IRC server
|
|
|
|
And like everyone else says, you cannot be sure on the server links
|
|
or other people on the channels or queries. You can only make sure that
|
|
**you** are using TLS.
|
|
|
|
One example where TLS is very helpful even if you have no idea whether
|
|
the other people use SSL is passwords:
|
|
|
|
* your NickServ password isn't in plain text between you and the IRC
|
|
server, but you again cannot know if the IRC server sends it to other
|
|
IRC server(s) in plain text that are between the server where you are
|
|
connected to and services server.
|
|
* your /OPER password in case you are IRC operator. Imagine being on
|
|
open WLAN or similar situation and transmitting your password in
|
|
plain text and someone else taking that password. What kind of "fun"
|
|
things they could do with it?
|
|
|
|
*Now you can move into reading why [IRC over SSL is pointless]...*

## Addition: who is interested in my traffic?
|
|
|
|
* Finland - Security Police & Defence Forces
|
|
* Currently law allowing Security Police and the Defence Forces to do
|
|
network monitoring without limitations is going to pass in the
|
|
parlament.
|
|
* Sweden - National Defence Radio Establishment & Security Police & Police
|
|
* Sweden has monitored all traffic going through them since 2008
|
|
and most of Finnish traffic goes through them.
