WEBVTT 00:00.180 --> 00:01.290 Welcome back guys. 00:01.350 --> 00:07.830 In this lecture we're going to talk about SSL what it is what we use it for how it works. 00:07.830 --> 00:13.660 Also about CDM and why the SSL and the CDM comparability is so important. 00:13.770 --> 00:20.160 Now first off what is SSL and what makes it so important then people are willing to pay for it. 00:20.520 --> 00:23.850 Well let's start by defining what SSL means. 00:23.850 --> 00:32.060 Now SSL means secure sockets layer and basically that's a fancy name for saying that it is a security 00:32.070 --> 00:35.430 protection between the client and the server. 00:35.430 --> 00:36.150 Right. 00:36.150 --> 00:40.200 So it's going to be protecting the client and the server transfers. 00:40.230 --> 00:45.030 Now the best way to really explain this in depth is to actually show you what I mean. 00:45.690 --> 00:50.940 So let's say that we have our clients and the client could be your users using your web site it could 00:50.940 --> 00:55.790 be you using a Web site you logging into your own Web site et cetera et cetera. 00:55.830 --> 00:57.270 So let's say that you have a log in. 00:57.270 --> 01:00.360 People have their password and their user name and everything. 01:00.360 --> 01:04.830 So what they're gonna do is that they're going to log in and therefore send their username and their 01:04.830 --> 01:11.790 password and it's going to be sent from them from their computer to the servers. 01:11.790 --> 01:12.380 Right. 01:12.390 --> 01:16.010 And then this server is going to fetch it and it's going to log them in. 01:16.020 --> 01:17.760 Now here's the problem. 01:17.880 --> 01:24.820 You see that when Mr. Hacker pops up in the picture which unfortunately has become a commonplace today. 01:24.820 --> 01:28.260 He is going to be able to sue in on that thing. 01:28.290 --> 01:33.310 He's going to be able to sue me in on the transfer itself between the client and between your web site 01:33.810 --> 01:41.310 see your username and password and suddenly you or that client has been hacked and that is terrible. 01:41.310 --> 01:46.500 Now you don't want this to happen especially not when you're having some form of e-commerce or if you're 01:46.500 --> 01:52.890 handling sensitive information or just for your own log into your own Web site that can break your entire 01:52.940 --> 01:54.000 Web site. 01:54.000 --> 01:59.070 Now of course thankfully we have backup and everything but this is not something that you want to happen 01:59.370 --> 02:05.700 especially not knowing that people might be sharing valuable information of their private information 02:05.700 --> 02:10.380 with you with their log in credit card information et cetera et cetera. 02:10.380 --> 02:12.940 So here is the solution guys. 02:13.050 --> 02:17.430 Encryption and encryption is exactly what SSL offers. 02:17.430 --> 02:23.280 So now when we're using SSL it looks like this since that we have our clients who is then going to be 02:23.280 --> 02:25.200 logging into your Web site. 02:25.200 --> 02:25.770 Right. 02:25.770 --> 02:31.170 He's going to have his user name and it's password but not when it's sending the information towards 02:31.170 --> 02:32.410 the server. 02:32.460 --> 02:35.760 It's actually going to go through an encryption right. 02:35.760 --> 02:38.210 This is the SSL encryption. 02:38.370 --> 02:44.340 So that means that when the transfer is happening between declined and the server it's no longer going 02:44.340 --> 02:47.250 to say user one two three pass from one to three right. 02:47.550 --> 02:53.010 It's not going to say the user name and the actual password instead is going to look something like 02:53.010 --> 02:58.950 this is just going to be random digits and numbers impossible to know what it actually says and what 02:58.950 --> 03:00.720 it actually means. 03:00.720 --> 03:05.340 So then it's going to be received by the server with this really strange information. 03:05.340 --> 03:11.640 But thanks to the SSL that means that when the server gets this information is going to be decrypted 03:12.090 --> 03:18.320 and that means that the server can get the real information and use it and log that claim in safely. 03:18.330 --> 03:21.170 So now should Mr. Hacker appear. 03:21.180 --> 03:24.080 Apparently there's only one hacker in the world in this story. 03:24.150 --> 03:29.850 Should the hackers appear that means that they're going to assume in on that encryption. 03:29.850 --> 03:30.480 Right. 03:30.510 --> 03:35.100 And if they go ahead and grab that encryption they have no idea what it means and they can't do anything 03:35.100 --> 03:36.330 valuable with it. 03:36.600 --> 03:44.130 And this is why SSL is so important and it is so valuable for security for yourself for everyone who 03:44.130 --> 03:47.940 uses it you need to have your Web site SSL secured. 03:48.060 --> 03:48.620 OK. 03:48.690 --> 03:51.520 So then let's move on to CDM. 03:51.530 --> 03:57.120 Now the thing with the SSL encryption is that the encryption is going through the blue host service 03:57.120 --> 04:02.250 because we're using blue host and we're getting a free SSL who's only going to work through the blue 04:02.250 --> 04:09.300 host servers but with CDM you're going to be using a bunch of different servers and unless you're paying 04:09.300 --> 04:16.920 for your SSL certificate you won't be able to apply that to the other service that you're using because 04:16.920 --> 04:21.270 of all of these different servers they're going to be all around in the world right. 04:21.720 --> 04:27.120 So that means that your website and your content material the people be visiting on your Web site they 04:27.120 --> 04:29.600 will be uploaded in different parts of the world. 04:29.600 --> 04:36.630 So for example if someone is in Norway in Europe or someone is in Australia or New Zealand et cetera 04:36.630 --> 04:42.240 et cetera then there's going to be a closer server most likely then we're blue hostess and they're going 04:42.240 --> 04:47.340 to be a faster page load they're going to get the content much faster they're going to have a much better 04:47.340 --> 04:56.490 user experience but we needed to be encrypted still and the free SSL does not offer that with the CDM. 04:56.580 --> 05:03.380 But here is the solution and this is why this is so perfect and that is CloudFlare now CloudFlare has 05:03.380 --> 05:05.730 this really amazing offer they have. 05:06.020 --> 05:15.380 Well for being a free citizen they are by far the widest and I would say best CDM offers out there right 05:15.410 --> 05:15.950 now. 05:15.950 --> 05:21.020 Now of course if you using Maxi design or something like that you can get more but the amazing thing 05:21.020 --> 05:25.190 with cloud four is that it's completely free and free is always in the budget. 05:25.190 --> 05:26.120 Right. 05:26.270 --> 05:33.580 But they're not only offering an amazing CDM they're also offering a free SSL certificate. 05:33.590 --> 05:35.140 So what that means is. 05:35.300 --> 05:42.710 And because for getting an SSL from CloudFlare that means that we get to have an SSL a secure encryption 05:42.710 --> 05:46.770 secure transfers while also using CDM. 05:46.850 --> 05:49.080 And it's not going to cost us a thing. 05:49.100 --> 05:51.440 So that is the amazing thing here. 05:51.710 --> 05:56.600 So in this business story we get a beautiful solution to the whole problem. 05:56.600 --> 06:02.540 So what we're gonna go ahead and do right now is in the next lecture we are gonna set up our CloudFlare 06:02.600 --> 06:06.080 see and we're actually going to set up our CloudFlare SSL. 06:06.230 --> 06:11.750 Get this party started and then make sure that our loading times are improving and our server response 06:11.750 --> 06:13.400 time is improving. 06:13.490 --> 06:13.930 OK. 06:14.000 --> 06:15.560 So see in the next lecture guys.
