We want to understand the trade-offs. We want to understand 47 00:02:55,000 --> 00:02:59,940 how they can be implemented into our lives so that we can decouple ourselves and be more 48 00:03:00,100 --> 00:03:05,240 decentralized in the way that we run our own technology stack. So with that being said, 49 00:03:05,880 --> 00:03:11,559 let's dive into Signal. How many people we have here this week? So we've got a few watching 50 00:03:11,560 --> 00:03:19,900 on X and on YouTube. We've got some watching over on zap.stream. So welcome to all the streamers 51 00:03:20,320 --> 00:03:25,860 that are here with us this weekend on this great and wonderful Friday. Could be morning, 52 00:03:26,060 --> 00:03:30,960 could be afternoon, wherever you are. It's Friday. It's the weekend. We are going to play 53 00:03:31,040 --> 00:03:36,899 with technology this weekend. Let me get the chat open up over here so I can see. If you want to 54 00:03:36,900 --> 00:03:41,800 participate in this show. This is a live show. You can feel free to comment. I'll see it 55 00:03:41,800 --> 00:03:48,000 in the chat and you can help steer what we look at here. I actually did get a comment 56 00:03:48,070 --> 00:03:53,300 on Noster when I posted the message about this going live soon. I had a user who posted 57 00:03:53,740 --> 00:03:59,480 something interesting that just got pushed out today on GitHub. It is a signal integration 58 00:03:59,900 --> 00:04:06,220 between Signal and a local AI so that you can interact with your local AI over Signal. 59 00:04:07,020 --> 00:04:16,420 I think that's really compelling. Signal has, to my understanding, there aren't easy ways to do 60 00:04:16,760 --> 00:04:22,500 bot integrations with Signal. And some of that has to do with privacy security. I think some 61 00:04:22,500 --> 00:04:29,039 of it has to do with not wanting the platform to get overtaken with bot spam. That's not an 62 00:04:29,040 --> 00:04:35,180 area that I've really taken a deep dive into yet, but this is really compelling because it would be 63 00:04:35,220 --> 00:04:42,600 awesome to be able to have a trusted AI. Local is one of the safest ways to use AI, so it'd be 64 00:04:42,800 --> 00:04:49,680 awesome to invite that into a Signal chat. We've been exploring this with Maple AI. How do we take 65 00:04:49,820 --> 00:04:57,019 the most private cloud AI that exists and integrate it into Signal, which in my mind is one of the 66 00:04:57,020 --> 00:05:03,400 safest text messaging platforms out there. So this is a compelling project and we'll pull it up here 67 00:05:03,440 --> 00:05:08,340 on the stream in just a little bit. So what are you going to get today over the next, we have 25 68 00:05:08,500 --> 00:05:13,300 minutes left, right? What are we going to get over the next 25 minutes? We are going to look at what 69 00:05:13,400 --> 00:05:18,740 is Signal. It's probably something you've heard of. I'm guessing a lot of viewers and listeners 70 00:05:19,140 --> 00:05:24,320 here, if you're live or listening to this later, you probably use Signal already. But if you don't, 71 00:05:25,300 --> 00:05:27,620 then let's give you a primer on it. 72 00:05:27,830 --> 00:05:28,280 What is it? 73 00:05:29,440 --> 00:05:30,240 Who makes it? 74 00:05:30,920 --> 00:05:32,720 And then what are the security claims 75 00:05:32,870 --> 00:05:34,960 and the privacy claims that Signal makes? 76 00:05:35,650 --> 00:05:36,520 And are they legitimate? 77 00:05:37,920 --> 00:05:40,060 And what are the trade-offs that they're making? 78 00:05:40,520 --> 00:05:42,100 Because if you're going to use this 79 00:05:42,240 --> 00:05:44,140 to communicate with your loved ones, 80 00:05:44,770 --> 00:05:46,700 with friends, with work, 81 00:05:47,400 --> 00:05:49,720 co-workers, important business contacts, 82 00:05:50,010 --> 00:05:52,940 or if you are an activist 83 00:05:53,240 --> 00:05:55,280 that is dependent on this communication 84 00:05:55,280 --> 00:05:59,800 to send really important information that you don't want to have intercepted. 85 00:06:00,880 --> 00:06:02,120 Are all these claims true? 86 00:06:03,620 --> 00:06:06,180 I don't know that we'll be able to get to the bottom of it all today, 87 00:06:06,590 --> 00:06:12,180 but I want to help you know where to look and start this exploration 88 00:06:12,770 --> 00:06:16,040 so that you can continue it because everybody's situation is different. 89 00:06:16,360 --> 00:06:19,280 Everybody has their own personal security profile and needs. 90 00:06:19,890 --> 00:06:24,540 And so I always recommend that people continue the search on their own 91 00:06:24,540 --> 00:06:27,580 and figure out if this is the right technology to work into your stack. 92 00:06:28,740 --> 00:06:31,500 Signal really came into the limelight over the last few weeks 93 00:06:32,190 --> 00:06:37,360 when allegedly some high-ranking United States government officials 94 00:06:38,479 --> 00:06:42,340 accidentally or didn't accidentally invite in journalists 95 00:06:42,620 --> 00:06:50,140 as they were having discussions about bombings and other war-type events. 96 00:06:51,760 --> 00:06:55,020 So take that for what it is. 97 00:06:55,540 --> 00:06:59,080 Let's go ahead and share the screen and dive into Signal here. 98 00:07:00,220 --> 00:07:07,420 I'm going to pull up screen share and start sharing the screen of my private server that I have. 99 00:07:07,500 --> 00:07:12,420 This is the server where we do all of our Freedom Tech weekend stuff. 100 00:07:20,300 --> 00:07:20,700 Okay. 101 00:07:21,000 --> 00:07:22,500 Okay, great. 102 00:07:24,040 --> 00:07:25,900 Making sure it's all set up and ready to go. 103 00:07:26,720 --> 00:07:27,500 Share screen. 104 00:07:28,500 --> 00:07:30,580 We are up to 15 people watching now. 105 00:07:30,760 --> 00:07:31,420 Welcome everybody. 106 00:07:36,790 --> 00:07:38,560 Okay, now I'm gonna make sure that on YouTube 107 00:07:38,850 --> 00:07:39,840 that the screen is sharing, 108 00:07:39,950 --> 00:07:42,880 'cause sometimes it doesn't work. 109 00:07:43,500 --> 00:07:45,340 And I did an entire stream one time 110 00:07:46,130 --> 00:07:47,300 where the screen was not sharing 111 00:07:47,370 --> 00:07:49,580 and it was like womp, womp, that stuff. 112 00:07:50,900 --> 00:07:53,060 Now that I'm on here, this looks good. 113 00:07:53,410 --> 00:07:57,200 I also want to make my window a circle. 114 00:07:59,440 --> 00:08:01,640 One of these days I'm going to figure out how to make that the default. 115 00:08:03,360 --> 00:08:04,020 There we go. 116 00:08:04,720 --> 00:08:07,080 Looks like we're streaming live everywhere. 117 00:08:07,480 --> 00:08:08,380 The screen is being shared. 118 00:08:08,800 --> 00:08:08,880 Great. 119 00:08:09,680 --> 00:08:11,740 I've got two things open on my screen here. 120 00:08:12,820 --> 00:08:16,220 For all the people that are listening to this on audio later on the podcast, 121 00:08:16,880 --> 00:08:22,200 I always try to tell as much of what we're seeing visually so that you can follow along. 122 00:08:22,940 --> 00:08:27,020 On the right side here, the whole thing is the Orion browser. 123 00:08:27,150 --> 00:08:30,580 So on the right side, I've got Orion opened up to the Signal website, 124 00:08:31,120 --> 00:08:35,780 as well as a few tabs here that will go through like Signal's GitHub, their community page, 125 00:08:36,330 --> 00:08:41,260 and then a new project, the Signal bot that chats with your local AI. 126 00:08:42,140 --> 00:08:43,400 I've got that open up on the tab. 127 00:08:43,760 --> 00:08:46,760 That was honestly hot off the press as it was released just a few hours ago. 128 00:08:47,480 --> 00:08:52,040 I don't know anything about it other than I do follow the person on Noster. 129 00:08:52,550 --> 00:08:55,060 So we'll take a look and see what's going on. 130 00:08:55,560 --> 00:08:57,980 And then on the left side of the screen, I have Maple open. 131 00:08:58,330 --> 00:08:59,040 This is Maple AI. 132 00:08:59,270 --> 00:09:01,620 You can go check it out at trymaple.ai. 133 00:09:02,080 --> 00:09:05,820 Or you can go on the Apple App Store and search for Maple AI and look for the green leaf. 134 00:09:08,260 --> 00:09:11,520 And use the world's most private AI chat in the cloud. 135 00:09:12,760 --> 00:09:13,480 This is what we make. 136 00:09:13,620 --> 00:09:19,160 on Freedom Tech Weekend. We don't have any sponsors. We don't ask for you to subscribe 137 00:09:19,980 --> 00:09:25,100 money-wise to this show, but I'm one of the two people that makes Maple AI, 138 00:09:25,840 --> 00:09:30,420 and I would love for you to try it out. So just go get a free account, and when you see the value 139 00:09:30,520 --> 00:09:35,460 in having end-to-end encrypted private AI chat, upgrade to one of the premium plans because you're 140 00:09:35,460 --> 00:09:40,259 going to get so much more value out of it when you do. Okay, but we use Maple every week on this 141 00:09:40,260 --> 00:09:45,240 show to help us understand what we're looking at. So this week, this is a brand new feature, 142 00:09:45,380 --> 00:09:51,080 by the way, in Maple is the ability to edit the system prompt. Our system prompt is open source. 143 00:09:51,500 --> 00:09:56,060 Maple is open source. You can see our system prompt is basically zero. We don't do much to 144 00:09:56,060 --> 00:10:02,180 the system prompt. You can see what it is. And then we added the ability for users to add to 145 00:10:02,180 --> 00:10:07,519 the system prompt in a new chat. So that's what I've done here. I've created a character, if you 146 00:10:07,520 --> 00:10:12,620 will, IT security researcher that works with the executive team. You are a security researcher who 147 00:10:12,660 --> 00:10:16,520 understands cryptography and data transmission technology at a deep level. You're regularly 148 00:10:16,700 --> 00:10:20,580 called upon to present findings and recommendations to high-level officials who don't have strong 149 00:10:20,740 --> 00:10:25,140 technical expertise. And I wrote quite a bit more in here, but basically I want Maple to get in this 150 00:10:25,220 --> 00:10:30,260 frame of mind where it's going to understand deep technical privacy issues, but know how to explain 151 00:10:30,540 --> 00:10:36,999 them, you know, at a 30,000 foot level, at a high level there. And now I'm going to actually write 152 00:10:37,000 --> 00:10:41,200 my prompt. I'm preparing to recommend the Signal messaging app to my large organization. I think 153 00:10:41,220 --> 00:10:45,160 it is great, but I need to be prepared to answer questions about how private and secure it really 154 00:10:45,240 --> 00:10:55,860 is.

Do they have source 200 00:13:53,920 --> 00:13:57,780 code and what's going on there? So let's flip over to the GitHub. You can get there by the way. 201 00:13:58,280 --> 00:14:03,360 We scroll all the way to the bottom of their website and you've got the GitHub link right 202 00:14:03,420 --> 00:14:07,800 here. So you can get to them that way. Try to get the chat open up here again. There we go. 203 00:14:08,520 --> 00:14:13,799 Okay. So we're over on their GitHub now and they have different projects. They have their Android 204 00:14:13,800 --> 00:14:20,180 app, iOS app. They have the desktop app. They've got a Signal server, and then they've got a 205 00:14:20,390 --> 00:14:25,120 library that's shared with a bunch of primitives and stuff that's shared between all the different 206 00:14:25,220 --> 00:14:29,140 projects. So those are their five that they have pinned at the top. I'm going to assume that they're 207 00:14:29,140 --> 00:14:34,540 a lot more. Yeah, they've got like WebRTC. Signal has a variety of features we'll look at here in 208 00:14:34,540 --> 00:14:41,520 just a second. And then they've got their own libraries, their pods and things that they share. 209 00:14:41,760 --> 00:14:42,760 so it looks like they're using CocoaPods 210 00:14:42,890 --> 00:14:43,840 for the iOS development. 211 00:14:46,200 --> 00:14:47,100 I'll forget them for that. 212 00:14:48,840 --> 00:14:50,460 Okay, they got a lot of repositories. 213 00:14:50,980 --> 00:14:52,420 So they're very active. 214 00:14:53,260 --> 00:14:53,740 Let me go back. 215 00:14:55,060 --> 00:14:56,800 I also like to look at how active things are. 216 00:14:57,500 --> 00:14:58,420 As I'm going through this, 217 00:14:58,780 --> 00:15:00,440 hopefully I'm kind of teaching you some ways 218 00:15:00,590 --> 00:15:02,200 for you to vet projects on your own. 219 00:15:02,660 --> 00:15:03,880 Go look at their open source, 220 00:15:04,130 --> 00:15:05,440 go look at GitHub or GitLab, 221 00:15:05,700 --> 00:15:07,100 wherever they decide to host it, 222 00:15:07,530 --> 00:15:09,100 and see how active it is, right? 223 00:15:09,860 --> 00:15:14,620 Sometimes you might stumble across a project that looks really cool and it hasn't been active in a few years, 224 00:15:16,040 --> 00:15:18,720 which lets you know that it is not being maintained. 225 00:15:19,940 --> 00:15:25,080 There could be vulnerabilities in there that have been exposed and not patched, right? 226 00:15:25,280 --> 00:15:31,180 Because a lot of these open source projects, pretty much all of them, have dependencies on other open source projects. 227 00:15:32,020 --> 00:15:36,060 And if somebody's not keeping theirs up to date, then some of their dependencies might have vulnerabilities. 228 00:15:37,200 --> 00:15:39,340 And by using it, you might make yourself vulnerable. 229 00:15:41,140 --> 00:15:48,300 so having active projects reduces your risk doesn't bring it down to zero though so let's 230 00:15:48,300 --> 00:15:55,380 go look at a signal server signal for android for ios for desktop okay we'll just kind of show you 231 00:15:55,980 --> 00:16:03,760 signal server 18 hours ago signal for android was active last week ios two days ago signal for 232 00:16:03,800 --> 00:16:09,540 desktop two days ago so yes they are doing active development please excuse my dog barking 233 00:16:09,540 --> 00:16:16,080 at the front door. They're doing signal, active development on everything here. Okay, they also 234 00:16:16,080 --> 00:16:19,660 have a community page, which acts as from the bottom. So they've got a whole spot where you 235 00:16:19,700 --> 00:16:24,400 can go chat with other Signal users. You can give them UI, UX feedback, feature requests. 236 00:16:24,880 --> 00:16:27,980 They have a whole beta program you can sign up for to try the latest beta stuff 237 00:16:28,820 --> 00:16:35,360 for Android, iOS, desktop, support, general discussion. So great, great community. I don't 238 00:16:35,360 --> 00:16:40,960 know how thriving it is to be honest but it's great that they have this okay some of the features 239 00:16:41,130 --> 00:16:46,640 like what is signal and why why do we want to use it so signal at a high level is an end-to-end 240 00:16:46,830 --> 00:16:54,560 encrypted text messaging application what that means is got booted off the dang screen share 241 00:16:54,780 --> 00:17:02,560 again hello everybody let's get this back going i don't know why restream keeps doing that 242 00:17:03,480 --> 00:17:08,180 Okay, Signal, when you, when you text with somebody on Signal, your message is encrypted 243 00:17:08,400 --> 00:17:13,120 on your device, privately, and then sent over to that person and decrypted on their device 244 00:17:13,520 --> 00:17:15,060 so nobody in the middle can see it. 245 00:17:15,579 --> 00:17:15,880 Right. 246 00:17:16,100 --> 00:17:23,319 It doesn't go to a server and sit there in the open for anybody on that server to read. 247 00:17:25,040 --> 00:17:30,280 It's also difficult for somebody in the middle to insert themselves and read the communication 248 00:17:30,280 --> 00:17:32,080 because it is a private encryption pipe 249 00:17:32,460 --> 00:17:33,840 between you and the other person. 250 00:17:34,390 --> 00:17:36,520 So even though things will be routed through servers, 251 00:17:39,080 --> 00:17:41,420 they're encrypted away from people on that server. 252 00:17:46,140 --> 00:17:48,760 So we asked Mabel to explain this to us. 253 00:17:50,720 --> 00:17:52,780 We're gonna check that out here right now. 254 00:17:54,540 --> 00:17:57,000 But real quick, the other high-level features 255 00:17:57,170 --> 00:18:00,260 is that Signal can do text messaging 256 00:18:00,260 --> 00:18:00,980 You can send images. 257 00:18:01,690 --> 00:18:02,300 You can send videos. 258 00:18:02,490 --> 00:18:03,640 You can send links to websites. 259 00:18:04,580 --> 00:18:08,220 And then you can also actually have audio and video calls through Signal, 260 00:18:09,020 --> 00:18:10,180 which I've used all of these features, 261 00:18:10,610 --> 00:18:14,620 and I depend on all these features every day, every week, 262 00:18:15,230 --> 00:18:18,040 for my personal life and for my business life. 263 00:18:18,480 --> 00:18:19,520 Mostly I've been using it for business. 264 00:18:20,400 --> 00:18:23,720 My goal is to kind of start using it for personal communications as well. 265 00:18:24,600 --> 00:18:29,520 And that really is, I think, the call to action here on this week's episode 266 00:18:29,520 --> 00:18:33,480 is, I'm going to, spoiler, I'm going to give it to you now, but I'll give it to you again at the end. 267 00:18:34,300 --> 00:18:39,760 Think about one contact that you have where you're chatting with them over a different text 268 00:18:40,020 --> 00:18:49,380 messaging app that is less secure. Whether that be regular text messages, I'm not talking the 269 00:18:49,560 --> 00:18:56,720 iMessage platform that is also encrypted, but when you go between Android and iOS, it's less secure. 270 00:18:57,540 --> 00:19:05,880 So find someone who you're chatting with that way or through something like WeChat or some other message, messenger, right? 271 00:19:06,780 --> 00:19:09,040 And get them to move over to Signal, just one person. 272 00:19:09,880 --> 00:19:11,380 And you start chatting with them there. 273 00:19:12,020 --> 00:19:12,100 Okay. 274 00:19:13,660 --> 00:19:14,180 All right. 275 00:19:14,280 --> 00:19:16,380 We're over 20 people watching the stream. 276 00:19:16,820 --> 00:19:17,400 Welcome, everyone. 277 00:19:18,280 --> 00:19:19,000 Great to have you. 278 00:19:19,720 --> 00:19:24,500 Feel free to post anything in the chat, any questions you have or ideas or ways that you like to use Signal. 279 00:19:24,620 --> 00:19:27,660 If you have found something really cool about Signal, go and post it in there. 280 00:19:28,580 --> 00:19:30,040 Okay, so Maple came back to us. 281 00:19:30,040 --> 00:19:33,500 It got this nice little diagram here that's super high level and simple. 282 00:19:34,420 --> 00:19:39,060 But at the high level, it says that their security can be thought of as a combination of three components. 283 00:19:39,620 --> 00:19:43,220 So you have end-to-end encryption, and then you have a secure key exchange, 284 00:19:44,160 --> 00:19:45,880 and then you have a secure server infrastructure. 285 00:19:47,440 --> 00:19:50,620 So with end-to-end encryption, Signal uses end-to-end encryption, 286 00:19:50,680 --> 00:19:54,780 which means that only the sender and intended recipient can read the message. 287 00:19:55,230 --> 00:19:58,280 This is achieved through the use of public key cryptography 288 00:19:58,790 --> 00:20:01,940 where each user has a pair of keys, a public key and a private key. 289 00:20:02,350 --> 00:20:05,520 So when you send a message, Signal encrypts it with the recipient's public key. 290 00:20:06,230 --> 00:20:09,180 The encrypted message is then transmitted to the Signal server. 291 00:20:09,290 --> 00:20:11,100 The server forwards a message to the recipient. 292 00:20:11,610 --> 00:20:14,660 The recipient's device decrypts the message using their private key. 293 00:20:15,380 --> 00:20:15,680 Okay. 294 00:20:17,720 --> 00:20:21,580 Public key, private key, these can be confusing terminologies. 295 00:20:22,100 --> 00:20:26,240 I think a lot of people that listen to Freedom Tech Weekend do already understand this. 296 00:20:26,800 --> 00:20:30,740 Really quick, what it means, if you don't, is it's a key pair. 297 00:20:31,400 --> 00:20:34,240 So when you generate a key pair, you get a public and a private key. 298 00:20:34,740 --> 00:20:39,620 The private key is your way to sign your message, to encrypt your message, right? 299 00:20:39,740 --> 00:20:41,100 And only you have access to that. 300 00:20:41,940 --> 00:20:44,220 So it's like your password in a way, right? 301 00:20:44,500 --> 00:20:53,880 So if I were going to write a handwritten letter and, you know, fold it up into a paper airplane, and that was just amazing. 302 00:20:53,950 --> 00:20:55,480 I could throw it anywhere in the world, right? 303 00:20:55,510 --> 00:20:57,880 And I'm going to throw it to you, and it's going to soar through the air. 304 00:20:58,210 --> 00:21:02,260 Well, that paper airplane could get intercepted at any moment by anyone and read. 305 00:21:02,900 --> 00:21:11,240 So I'm going to use my private key to jumble the text, and then I'm going to send it to you. 306 00:21:11,600 --> 00:21:15,020 And you receive it and you're like, well, this is all jumbled up. 307 00:21:15,180 --> 00:21:16,340 I don't know how to read this. 308 00:21:17,539 --> 00:21:25,280 So instead what I want to do is I want to use something that you know to decipher it. 309 00:21:26,060 --> 00:21:29,020 And so you have this public key that goes along with your private key. 310 00:21:29,620 --> 00:21:30,900 And so you give me your public key. 311 00:21:30,940 --> 00:21:32,340 This is the thing that can be shared. 312 00:21:32,440 --> 00:21:39,860 And it says anybody that's going to send something to me, encrypt it and include this public key in there. 313 00:21:40,160 --> 00:21:46,140 And then I will be able to decrypt it on my end because it was meant for me. 314 00:21:46,790 --> 00:21:51,920 And because you have the private key that goes along with that public key, you are able to decrypt it. 315 00:21:53,060 --> 00:21:57,040 That's a high level how private public key pairs work. 316 00:21:58,260 --> 00:22:03,160 So what Signal does is they use that and they have step number two is a secure key exchange. 317 00:22:03,460 --> 00:22:09,520 Signal uses a protocol called the Ended Triple Diffie Helm X3DH 318 00:22:09,640 --> 00:22:12,940 key agreement protocol to securely exchange keys between users. 319 00:22:13,360 --> 00:22:16,180 This protocol allows users to establish a shared secret 320 00:22:16,360 --> 00:22:19,440 without actually exchanging the key itself. 321 00:22:21,239 --> 00:22:22,620 Right, I got to do that again. 322 00:22:25,900 --> 00:22:28,060 So when you start a conversation with someone, 323 00:22:28,260 --> 00:22:31,480 Signal generates a shared secret key using X3DH. 324 00:22:31,880 --> 00:22:35,220 This shared secret is then used to encrypt and decrypt messages. 325 00:22:36,100 --> 00:22:39,160 So it's using the private key, public key pair, 326 00:22:40,020 --> 00:22:42,240 and it is creating this new exchange 327 00:22:43,700 --> 00:22:45,600 and this new shared secret that you two have. 328 00:22:46,080 --> 00:22:48,340 And so you can share messages back and forth, 329 00:22:48,820 --> 00:22:52,900 and it blocks others from sniffing and from looking at the conversation. 330 00:22:53,760 --> 00:22:56,960 And then number three is the Signal's secure server architecture. 331 00:22:57,840 --> 00:23:00,179 Their infrastructure is designed to be secure 332 00:23:00,180 --> 00:23:02,100 and minimize the risk of data breaches, 333 00:23:02,260 --> 00:23:05,160 Signal uses a technique called metadata minimization, 334 00:23:05,480 --> 00:23:07,280 which means that the server only stores 335 00:23:07,420 --> 00:23:09,060 the minimum amount of information necessary 336 00:23:09,280 --> 00:23:10,180 to facilitate communication. 337 00:23:11,120 --> 00:23:12,960 By the way, this is what Maple does as well. 338 00:23:13,360 --> 00:23:17,140 We retain the lowest amount possible on our servers 339 00:23:17,380 --> 00:23:20,480 to allow you to chat privately with the AI. 340 00:23:21,540 --> 00:23:24,140 Signal servers do not store any message content. 341 00:23:24,740 --> 00:23:26,540 Signal servers only store the phone numbers 342 00:23:26,860 --> 00:23:28,740 and public keys of registered users. 343 00:23:29,720 --> 00:23:34,800 Some other security features worth mentioning include perfect forward secrecy. 344 00:23:35,300 --> 00:23:38,620 Signal uses a technique called perfect forward secrecy. 345 00:23:38,840 --> 00:23:39,540 That's a mouthful. 346 00:23:40,080 --> 00:23:47,460 Which means that even if an attacker obtains a user's private key, they will not be able to decrypt any previous messages. 347 00:23:48,860 --> 00:23:50,460 Forward secrecy is something that's really cool. 348 00:23:50,940 --> 00:23:52,420 I recommend you dive into it more. 349 00:23:52,900 --> 00:23:54,780 We don't have enough time here to really go into it. 350 00:23:55,660 --> 00:24:00,800 But it's the thing where, let's say that you have this really long text thread going with somebody. 351 00:24:01,540 --> 00:24:07,680 Say that you are a journalist and you have an activist who is in a country that is trying to expose corruption. 352 00:24:08,960 --> 00:24:11,900 And you have this long going text thread with them over signal. 353 00:24:13,420 --> 00:24:20,740 And then at some point, one of your devices gets, well, one of your private keys gets compromised, right? 354 00:24:21,100 --> 00:24:25,940 So someone is somehow able to get a hold of accessing your signal private key. 355 00:24:27,100 --> 00:24:34,820 And now they try to log in and see, well, the previous messages will not be available to them. 356 00:24:35,450 --> 00:24:37,740 They will only be able to see things moving forward. 357 00:24:39,420 --> 00:24:42,000 You still don't want to give up and compromise your private key, 358 00:24:42,330 --> 00:24:45,640 but this ensures that the history will not be able to be read. 359 00:24:47,410 --> 00:24:51,000 Okay, next bullet point here on the other features worth mentioning. 360 00:24:51,080 --> 00:24:58,060 we have authentication signal uses a technique called oh man sometimes ai is is not great 361 00:24:58,560 --> 00:25:03,220 signal uses a technique called authentication to verify the identity of users this ensures that 362 00:25:03,300 --> 00:25:08,400 you're actually communicating with the person that you think you are so it sounds silly 363 00:25:08,960 --> 00:25:13,860 authentication right but something that signal actually does is they have um i think it's called 364 00:25:13,860 --> 00:25:19,519 a buddy code or something i can't remember the specific name that they use um but basically when 365 00:25:19,520 --> 00:25:25,480 you connect with somebody, there's this little extra step that they do for you to say, hey, 366 00:25:25,520 --> 00:25:29,040 do you just want to verify that this person is really who they say they are? And then 367 00:25:29,200 --> 00:25:34,020 actually, over the lifetime, if that person you're chatting with, if they change phone 368 00:25:34,120 --> 00:25:39,180 numbers or somehow kind of change what they're doing, you actually get a message in your 369 00:25:39,300 --> 00:25:45,139 chat that says, hey, this person, something changed about this user. So please just reach 370 00:25:45,140 --> 00:25:50,060 out to them in a way other than Signal to make sure that you're still talking to the right person. 371 00:25:50,490 --> 00:25:57,560 So they try to alert you when there's some funny behavior that's gone on. So I had a couple people 372 00:25:57,650 --> 00:26:03,080 that I chat with over Signal have some kind of change that was legitimate to them. It's still 373 00:26:03,130 --> 00:26:07,440 the same person I'm chatting with, but Signal alerts you to that and just says, hey, just 374 00:26:07,960 --> 00:26:12,760 letting you know you might want to verify that you're still chatting with the correct person here. 375 00:26:14,600 --> 00:26:20,520 Okay, third bullet point that is pointed out here by Maple is that they have code audits and transparency. 376 00:26:21,020 --> 00:26:26,960 Signal's code is open source, which means that security experts can review and audit the code to ensure it is secure. 377 00:26:27,860 --> 00:26:33,100 Signal also publishes transparency reports, which provide information about government requests for user data. 378 00:26:33,920 --> 00:26:39,020 These are all operating under a trust model, right? 379 00:26:39,220 --> 00:26:43,920 So we trust that the code running on their servers is the same as the open source code they publish. 380 00:26:44,120 --> 00:26:51,140 to my knowledge they're not using secure enclaves with attestation which we use at maple but they 381 00:26:51,200 --> 00:26:56,060 could and maybe they will in the future i've got a lot of respect for signal so far and how they've 382 00:26:56,060 --> 00:27:01,600 been pushing the envelope on things so it'd be great to see them use secure enclave infrastructure 383 00:27:01,950 --> 00:27:06,540 in the future and publish attestations that clients can use when talking to the signal servers 384 00:27:06,740 --> 00:27:12,539 so we know exactly what's running on there but people can do security audits and then it said 385 00:27:12,540 --> 00:27:16,120 here that they publish transparency reports so they say that when they get 386 00:27:16,200 --> 00:27:20,780 requests from governments they're going to publish those requests we can't 387 00:27:20,860 --> 00:27:26,980 verify that they publish all of them but it's great that they have this I have 388 00:27:27,120 --> 00:27:34,880 this this method and say that they're doing this okay download and sign up 389 00:27:36,320 --> 00:27:41,699 some of these tools are hard to show off on the stream specifically because they 390 00:27:41,700 --> 00:27:47,720 require they require like phone numbers and things but this is a server a Mac 391 00:27:47,840 --> 00:27:53,400 server that I'm on so I'll just do this here so you can download for Mac let it 392 00:27:53,400 --> 00:27:59,240 download and then like like all Mac applications it's gonna give us or most 393 00:27:59,290 --> 00:28:03,540 of them always right it's gonna give us this little window here where we drag it 394 00:28:03,620 --> 00:28:08,579 into the applications folder I'm not gonna get very far on this because I 395 00:28:08,580 --> 00:28:11,960 I don't have an extra phone number or privacy phone number to sign up with here. 396 00:28:12,690 --> 00:28:14,680 But let's go ahead and launch the Signal app. 397 00:28:17,550 --> 00:28:18,060 Doing a little verification. 398 00:28:19,070 --> 00:28:20,240 Warning, are you sure you want to open this? 399 00:28:20,290 --> 00:28:21,020 You got it from the internet? 400 00:28:21,350 --> 00:28:21,460 Yep. 401 00:28:24,640 --> 00:28:25,000 Okay. 402 00:28:25,630 --> 00:28:27,120 So, what are we getting here? 403 00:28:27,740 --> 00:28:30,460 This is a QR code, and it says, 404 00:28:30,690 --> 00:28:32,860 Scan this code in the Signal app on your phone. 405 00:28:34,620 --> 00:28:39,080 So Signal on the Mac and on the desktop really for Linux and Windows as well, the way that 406 00:28:39,120 --> 00:28:43,880 they operate is they assume that you are starting on a phone because you have to have a phone 407 00:28:43,940 --> 00:28:45,940 number to use Signal to get started. 408 00:28:46,420 --> 00:28:48,220 Your phone number is not exposed to everybody. 409 00:28:48,400 --> 00:28:50,020 You can choose who you want to share your phone number with. 410 00:28:50,180 --> 00:28:51,040 I have mine turned off. 411 00:28:52,160 --> 00:28:56,120 Instead, I have a Signal username and people can connect to me over the username because 412 00:28:56,180 --> 00:28:57,660 I don't want to expose my phone number. 413 00:28:58,280 --> 00:29:01,699 If you don't know why your phone number, why you should be more careful with that, you 414 00:29:01,700 --> 00:29:06,960 can look up things like SIM swap attacks. SIM as in like the SIM card in your phone. 415 00:29:08,100 --> 00:29:14,540 SIM swap attacks are ways for people to breach your security. So look into those. 416 00:29:15,330 --> 00:29:21,140 But so if I'm using Signal on my phone, then I got booted again. You're not even seeing my screen, 417 00:29:21,470 --> 00:29:29,500 dang it. Let's go back. Okay. So now we're back on. All right. So it shows this QR code here, 418 00:29:29,820 --> 00:29:31,700 and I go into my Signal app that I'm signed into, 419 00:29:32,300 --> 00:29:36,180 and I say tap on link devices under settings, 420 00:29:36,740 --> 00:29:37,820 and then I scan this QR code, 421 00:29:37,980 --> 00:29:40,620 and now it will link my desktop to my phone app, 422 00:29:41,300 --> 00:29:44,600 and it's going to create a private connection. 423 00:29:44,940 --> 00:29:46,300 Let's actually ask Maple really quick. 424 00:29:47,120 --> 00:29:54,320 When I link a desktop Signal app to my phone app, 425 00:29:55,200 --> 00:30:00,100 What is happening from a security standpoint? 426 00:30:01,700 --> 00:30:07,700 Why do I have to scan this QR code? 427 00:30:08,600 --> 00:30:09,820 Okay, let's see what they say. 428 00:30:16,440 --> 00:30:19,360 Okay, when you link the desktop signal app to your phone, 429 00:30:19,480 --> 00:30:22,760 you're establishing a desktop secure connection between the two devices. 430 00:30:23,240 --> 00:30:31,160 process is called device linking. It's creating a pre-shared secret. When you open the Signal 431 00:30:31,260 --> 00:30:37,620 desktop app for the first time, it generates a unique pre-shared secret, a PSK, to establish 432 00:30:37,710 --> 00:30:43,540 a secure connection between your desktop and phone. Then it generates a QR code that has 433 00:30:43,800 --> 00:30:48,439 the PSK along with some other information such as desktop apps, public key, and a unique 434 00:30:48,440 --> 00:30:56,140 identifier. When you scan the QR code with your phone, I just got a zap. Thanks for the zap. 100 435 00:30:57,440 --> 00:31:04,600 sats from an unknown user. Appreciate it. If anybody has any questions, also feel free to 436 00:31:04,650 --> 00:31:09,520 post those in the chat. So QR code, when you scan it with a signal app on your phone, the phone 437 00:31:09,660 --> 00:31:13,899 extracts the PSK and other information from the QR code. Then there's a key exchange. The phone 438 00:31:13,900 --> 00:31:18,800 app uses a PSK to establish a secure key exchange between the desktop app. This key exchange is done 439 00:31:18,960 --> 00:31:25,140 using the X3DH protocol, which is the same protocol used within Signal for End End Encryption. 440 00:31:25,880 --> 00:31:29,440 Then there's a secure channel established.
