1
00:00:00,040 --> 00:00:06,380
so now it's time to talk about a subject that is really important on tails and that is secure instant messaging.

2
00:00:06,400 --> 00:00:11,740
instant messaging is not like email, it's not like text or sending stuff back and forth on a website.

3
00:00:11,980 --> 00:00:14,760
instant messaging is what you probably use every day.

4
00:00:14,780 --> 00:00:19,910
most of the texting we do these days on our phones is a form of instant messaging.

5
00:00:19,910 --> 00:00:30,120
using something like imessage or using the frameworks offered by android, you're engaging in an ecosystem that allows back and forth instant communication, but in a secure way.

6
00:00:30,340 --> 00:00:35,520
now, there are a lot of popular instant messaging platforms that have existed on the internet for a long time.

7
00:00:35,740 --> 00:00:44,600
tools like jabber or aol chat, if you recall that have been really popular, but they did not offer very good encryption or security.

8
00:00:44,780 --> 00:00:47,920
these messages were likely wide open to the wider internet.

9
00:00:47,980 --> 00:00:52,190
anyone able to snoop on the traffic could most likely see them in plain text.

10
00:00:52,190 --> 00:01:01,760
obviously with email, we have options like pgp, but pgp is slow and for instant messaging, it probably is not a viable way to send and receive communications.

11
00:01:01,900 --> 00:01:08,240
any asymmetrical encryption like that is going to be way too slow for something like a stream with instant messaging.

12
00:01:08,980 --> 00:01:11,710
so what options do we have with tails?

13
00:01:11,710 --> 00:01:14,600
well, let's hop over to our tails desktop and take a look.

14
00:01:15,300 --> 00:01:22,690
so here on the tails desktop, there is one pre- installed, actually two now pre- installed applications for instant messaging.

15
00:01:22,690 --> 00:01:27,110
the 1st one i wanted to talk about that we covered earlier in this course is onion share.

16
00:01:27,110 --> 00:01:33,480
onion share is an application provided by the tor project, and they do actually have a chat feature in here.

17
00:01:33,500 --> 00:01:42,210
so we can start a chat server very simply in onion share, and then we can just give someone the link to that server so that they can chat back and forth with us.

18
00:01:42,210 --> 00:01:43,960
now this history isn't shared.

19
00:01:44,100 --> 00:01:53,610
it gets deleted when you close tor and it's over the encryption of the tor network, meaning it is encrypted along transit and generally a very safe protocol to use.

20
00:01:53,610 --> 00:02:03,520
so this is a great tool for one- off chatting, and i think it's gaining popularity in the online space, but it hasn't been a standard for a long time, so it's not as widely used.

21
00:02:03,700 --> 00:02:09,320
what is more widely used, and it comes pre- installed on tails is pigeon.

22
00:02:09,460 --> 00:02:15,750
pigeon is a chat client that allows you to use different im accounts on the back end.

23
00:02:15,750 --> 00:02:22,760
so if we wanted to add an im account, we can see the different protocols and we can make sure we sign in with that information.

24
00:02:23,020 --> 00:02:27,630
so you would have to go to a 3rd party tool to actually sign up for these accounts.

25
00:02:27,630 --> 00:02:36,280
now, this course is not going over the complexities of setting up instant messaging accounts and how to make sure they're secure, but it's important to know that pigeon is pre- installed.

26
00:02:36,980 --> 00:02:43,520
and another software that is available, we are just navigating to the site here to show you the documentation, is called dyno.

27
00:02:43,580 --> 00:02:53,510
and dyno with omimo, it's their security protocol, uses xmpp or jabber protocol for decentralized communication, but encrypts it.

28
00:02:53,510 --> 00:02:57,270
so this is a really useful tool that's gaining popularity as well.

29
00:02:57,270 --> 00:03:05,520
and you can actually set up dyno pretty easily entails by just going to their download page and you can check out the distribution packages or just straight download it.

30
00:03:05,860 --> 00:03:08,080
this is like any other service.

31
00:03:08,620 --> 00:03:10,050
so check out their website.

32
00:03:10,050 --> 00:03:13,160
it's just dyno, i believe, what was that?

33
00:03:14,300 --> 00:03:15,090
dyno.

34
00:03:15,090 --> 00:03:15,800
im.

35
00:03:15,900 --> 00:03:21,160
and you can go to their github page to see information about their available packages and install it very quickly.

36
00:03:21,300 --> 00:03:22,990
pretty easy to set up an account.

37
00:03:22,990 --> 00:03:24,710
i'll be making a separate guide.

38
00:03:24,710 --> 00:03:29,880
i'll attach a guide to this video on how to do this, but we're not going to go through all of the steps in this video.

39
00:03:29,900 --> 00:03:37,160
just wanted to make sure you were introduced to dyno and omimo and how to actually use those together for encryption and chatting.

40
00:03:37,300 --> 00:03:40,110
if you have any questions on this or would like a deeper dive, let me know.

41
00:03:40,110 --> 00:03:41,490
otherwise, definitely check out the discord.

42
00:03:41,490 --> 00:03:48,040
i think there is a secure instant messaging channel specifically for communication and thoughts around that.

43
00:03:49,540 --> 00:03:52,200
as always, thanks for watching and we'll see you in the next one.
