_IRC over TLS is not pointless unless you only worry about things that you
cannot affect at all. SSL is pointless, because of [POODLE]._
2024-06-19 07:19:44 +02:00
I use IRC over TLS on all networks that support it (=other than IRCnet) and I
also [verify the certificates]. TLS is used
2023-02-22 19:28:38 +01:00
_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
2024-06-19 07:19:44 +02:00
unencrypted. I am not able to use those though as Finnish channels are mostly
stupid and letting people only in from Finnish servers._
2023-02-22 19:28:38 +01:00
- between my client and bouncer
2024-06-19 07:19:44 +02:00
- 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`.
2023-02-22 19:28:38 +01:00
- between my bouncer and IRCd
2024-06-19 07:19:44 +02:00
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.
2024-06-19 07:19:44 +02:00
As I use TLS everywhere where I can affect, I can be more sure that my
discussions aren't so easily read on:
2023-02-22 19:28:38 +01:00
- open WLAN
- any router between me and the bouncer
- any router between bouncer and the IRC server
2024-06-19 07:19:44 +02:00
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.
2024-06-19 07:19:44 +02:00
One example where TLS is very helpful even if you have no idea whether the other
people use SSL is passwords:
2024-06-19 07:19:44 +02:00
- 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?

## Addition: who is interested in my traffic?

- Finland - Security Police & Defence Forces
2024-06-19 07:19:44 +02:00
- 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
2024-06-19 07:19:44 +02:00
- Sweden has monitored all traffic going through them since 2008 and most of
Finnish traffic goes through them.
