so if you ever want to do instant messaging on something like the dark web, if you ever want to use any sort of secure messaging that's not email based, well, you're going to hear about xmpp or jabber.
now these are essentially the same thing, but jabber is what it used to be called.
it's no longer called that anymore, but a lot of people still say jabber.
and in this video, we're going to talk about what xmpp actually is.
and in future videos, we're going to learn how to actually use it.
so xmpp is really just an open communication protocol.
it's an open standard, meaning that anyone can use it.
much like pgp, this standard sort of sets the baseline for building clients and services on top of it.
it was originally known as jabber, though xmpp is the correct term these days.
what's interesting about xmpp, because it's an open standard, anyone can actually run their own xmpp server.
and because of that, it's decentralized, right?
if anyone can run their own server, there's no central authority for xmpp.
and it's generally used for instant messaging or instant communication.
some common clients when it comes to xmpp that you'll hear of are pigeon, which is already built into tails.
gajim, it's the newer and more widely used one instead of pigeon and dyno, which i previously saw was going to start being baked into tails as well, although i'm not sure if they've done that quite yet.
so we'll talk about all three of those in this course and how to actually set up xmpp on it.
there are a ton of other xmpp clients that you might find or be interested in.
if there's any you think we should cover, definitely let me know.
otherwise, let's continue on to start actually using some of these clients.
