1 00:00:18,140 --> 00:00:23,130 Let us continue with the application, their protocols in this lecture. 2 00:00:23,270 --> 00:00:28,850 We are going to see its GDP as it is hypertext transfer protocol secure. 3 00:00:30,550 --> 00:00:34,050 A more secure version of its GDP is its GDP. 4 00:00:34,660 --> 00:00:38,590 But before lending its GDP, we should learn what is SSL? 5 00:00:39,280 --> 00:00:42,190 SSL secure connections between two computers. 6 00:00:42,920 --> 00:00:48,100 Each time a pair of computers want to securely, they agree on an encryption key. 7 00:00:49,540 --> 00:00:57,010 This is created randomly for each connection in simple terms, SSL, which is secure sockets layer, 8 00:00:57,190 --> 00:01:02,710 is one of the security technology which is used to establish a secure connection between Web server 9 00:01:02,890 --> 00:01:03,820 and Web browser. 10 00:01:04,660 --> 00:01:11,590 This secure link is encrypted format, so it assures users the data which is passed between this link 11 00:01:11,740 --> 00:01:15,550 means the server and browser is private and original. 12 00:01:16,810 --> 00:01:23,590 SSL is an industry standard protocol which is used by several websites are predicting that online transactions 13 00:01:23,590 --> 00:01:24,640 with the customers. 14 00:01:26,090 --> 00:01:31,670 Essentially, and it is also difficult, it is a sign of trust, basically, between your website. 15 00:01:32,750 --> 00:01:38,060 If your website has an online store and request car payments and assistance are difficult difficulties, 16 00:01:38,060 --> 00:01:41,570 like a digital handshake between your site and there's. 17 00:01:43,020 --> 00:01:50,280 This sense of trust allows you to process the car payment securely, Google now records all e-commerce 18 00:01:50,280 --> 00:01:54,750 websites to install and it's a little difficult to ensure maximum safety. 19 00:01:55,410 --> 00:02:01,140 Google is even blacklisting certain sites that do not carry assault certificates and lowers their Google 20 00:02:01,680 --> 00:02:09,870 ranking SSL certificates, thankfully, can be found for free from Let's Encrypt, Let's Encrypt is 21 00:02:09,870 --> 00:02:16,220 a Google sponsored initiative to provide SSL certificates freely coming back to DPS. 22 00:02:17,310 --> 00:02:23,550 It's pretty obvious, encrypts all the information that is sent and received, this can stop malicious 23 00:02:23,550 --> 00:02:23,950 users. 24 00:02:23,970 --> 00:02:29,520 It is hackers from stealing the information and is often used on payment websites. 25 00:02:30,440 --> 00:02:38,510 It refers to a combination of BP and SSL to implement secure communication between a Web browser and 26 00:02:38,520 --> 00:02:39,120 a Web server. 27 00:02:40,170 --> 00:02:44,360 Its deepest capability is built into all modern Web browsers. 28 00:02:44,820 --> 00:02:52,170 The principle difference in bi user of a web browser is that in the US that address begins with its 29 00:02:52,170 --> 00:02:52,740 GDP. 30 00:02:52,740 --> 00:03:03,810 Is Golan's less less unlike its GDP, Gordon Sless less if it's GDP as specified or 443 is used, which 31 00:03:03,810 --> 00:03:05,130 invokes SSL. 32 00:03:06,230 --> 00:03:10,470 When it is used, the following elements of communication are encrypted. 33 00:03:10,940 --> 00:03:18,570 First, the order of requested document, then contains a document, contains a browser, forms cookies 34 00:03:18,570 --> 00:03:24,650 sent from browser to server and from server to browser, and last the contents of its GDP header. 35 00:03:25,220 --> 00:03:26,420 Consider a scenario. 36 00:03:27,050 --> 00:03:31,130 In first case, you send a message to a friend via a mutual friend. 37 00:03:31,730 --> 00:03:35,270 Your friend receives the message and may respond back if needed. 38 00:03:35,900 --> 00:03:37,930 This is its GDP here. 39 00:03:37,940 --> 00:03:43,130 Someone can recover the message in the way from that mutual friend by some means, like blackmailing 40 00:03:43,130 --> 00:03:44,180 or even gun pointing. 41 00:03:45,030 --> 00:03:50,970 Consumers second guess you send the same message to a friend through the same mutual friend, but this 42 00:03:50,970 --> 00:03:57,030 time your mutual friend is being accompanied by the bodyguards and gunman, that is the SSL encryption, 43 00:03:57,510 --> 00:04:00,180 which will only allow your friend to receive the message. 44 00:04:00,630 --> 00:04:03,060 Your friend receives the message and may respond. 45 00:04:03,750 --> 00:04:05,900 This is a debate here. 46 00:04:05,910 --> 00:04:12,030 It is next to impossible to recover the message in any way or simply eavesdropping is not possible due 47 00:04:12,030 --> 00:04:12,810 to bodyguards. 48 00:04:13,110 --> 00:04:20,400 Simply, it's your DPS means that the request made to the website are encrypted and cannot be decrypted 49 00:04:20,580 --> 00:04:26,280 unless the property is used so as to prevent attacks like eavesdropping and man in the middle. 50 00:04:26,700 --> 00:04:29,310 Let's move on to 11 pages of attributes. 51 00:04:29,910 --> 00:04:35,030 In most cases, sites turning over its steps will have a redirect in place. 52 00:04:35,340 --> 00:04:39,390 Therefore, even if you type in its GDP, Golan's less less. 53 00:04:39,570 --> 00:04:46,620 It will redirect its GDP over a secure connection more secure than it should be, obviously, because 54 00:04:46,620 --> 00:04:52,830 encryption is accompanied by its steps as technology protects any user and builds trust. 55 00:04:53,070 --> 00:04:59,940 Like I say, in the real life example, bodyguards, each is a difficult conditions, unique, authenticated 56 00:04:59,940 --> 00:05:01,850 information about the certificate. 57 00:05:02,820 --> 00:05:06,380 Now let us have a quick recap of what we learned in this lecture. 58 00:05:07,050 --> 00:05:11,340 We started this and then we move forward two steps. 59 00:05:11,820 --> 00:05:18,360 Then we took a real life scenario and explained the difference between its GDP and its GDP and thereby 60 00:05:18,570 --> 00:05:21,720 concluded with advantages of Astreus.
