1 00:00:00,270 --> 00:00:06,689 Our initial functionality works just fine, but when it comes to verification token. 2 00:00:07,620 --> 00:00:11,670 Setting it up as fake token production is kind of silly. 3 00:00:12,180 --> 00:00:22,050 What you want is unique token for each user, so user registers he or she gets that unique token and 4 00:00:22,050 --> 00:00:23,940 then will proceed to the next steps. 5 00:00:24,600 --> 00:00:27,390 At the moment, all of them will have this fake token. 6 00:00:27,750 --> 00:00:31,080 Now there's various ways how we can set this up. 7 00:00:31,680 --> 00:00:38,240 We can use maybe a unique I.D. library like you, I.D. and stuff along those lines. 8 00:00:38,250 --> 00:00:45,060 But there's also a nifty are set up, at least in my opinion, where we can use a crypto library which 9 00:00:45,060 --> 00:00:51,630 is actually built into a node so we don't need to install anything extra or anything like that. 10 00:00:52,020 --> 00:00:54,600 So let's go above, what do we have right now? 11 00:00:55,050 --> 00:01:01,920 Batch cookies and right after that, we're going to go with Konst Crypto, and that is equal to require. 12 00:01:02,220 --> 00:01:06,570 So Let just required a package and we're looking for a crypto package. 13 00:01:07,080 --> 00:01:07,860 I must say. 14 00:01:08,740 --> 00:01:14,200 Let's keep on scrolling and what we're looking for is this verification token, and now instead of this 15 00:01:14,200 --> 00:01:16,810 fake token, here's what we're going to do. 16 00:01:17,350 --> 00:01:18,820 I'm going to remove everything. 17 00:01:19,150 --> 00:01:20,380 We're going to go with crypto. 18 00:01:21,010 --> 00:01:26,290 So that's what we're getting back from the library and the method name is random bytes. 19 00:01:27,130 --> 00:01:34,280 So essentially, this is going to create a buffer with around them bytes and you can pass here the number. 20 00:01:34,480 --> 00:01:36,310 And in my case, I'm going to go with 40. 21 00:01:36,880 --> 00:01:43,480 Now, since this is a buffer, I actually want to turn it into a string on a buffer. 22 00:01:43,490 --> 00:01:50,350 We have this method called two string, which effectively does turn it into a string, and by default, 23 00:01:50,350 --> 00:01:52,510 the encoding is going to be UTF eight. 24 00:01:52,990 --> 00:01:57,880 But what we want to set it up as hex where effectively. 25 00:01:58,930 --> 00:02:04,120 Each bite is going to be encoded as two hexadecimal characters. 26 00:02:04,480 --> 00:02:08,199 Now I understand that this is kind of a lot at the end of the day. 27 00:02:08,620 --> 00:02:13,990 You need to understand or just get this random big string value. 28 00:02:14,440 --> 00:02:15,430 So let's try to do that. 29 00:02:15,730 --> 00:02:21,100 We're going to go with crypto random byte to string its passed in the Hex. 30 00:02:21,820 --> 00:02:27,820 And then let's say it again, since we're still testing everything, like I said, she's going to be 31 00:02:27,820 --> 00:02:29,820 a little bit annoying where you need to go back. 32 00:02:29,830 --> 00:02:31,060 At least I'm going to do that. 33 00:02:31,750 --> 00:02:38,920 I'm going to remove Anna, and let's try to register one more time and you'll see how the value actually 34 00:02:39,310 --> 00:02:41,860 will be that random bytes one. 35 00:02:42,340 --> 00:02:43,300 So it's four more. 36 00:02:43,990 --> 00:02:50,440 Now we want to navigate back to our postman and instead of register, or I'm sorry, instead of login, 37 00:02:51,040 --> 00:02:54,550 we'll go with the register again, send back and now check it out. 38 00:02:55,180 --> 00:03:00,490 So we have this random bytes value and this is exactly what we're looking for. 39 00:03:00,670 --> 00:03:07,810 We have this random string, which we're going to use in order to verify the email.
