1
00:00:00,510 --> 00:00:07,920
Before starting this hour and just increased this exploration time so that it won't expire within 30

2
00:00:07,920 --> 00:00:12,230
seconds for that and go to the main class and start the summer.

3
00:00:12,510 --> 00:00:16,040
Meanwhile, I'll also open the login page of the application.

4
00:00:16,320 --> 00:00:18,770
So now we are on to the login page of the application.

5
00:00:18,780 --> 00:00:20,790
Let's try to open the console as well.

6
00:00:21,030 --> 00:00:24,330
Entering the credentials of the user on submitting.

7
00:00:24,330 --> 00:00:29,980
I'm able to login successfully if you go and see to the application tab.

8
00:00:30,000 --> 00:00:36,150
There are no cookies right now sealed, which is one of the secure approach that we are going to follow

9
00:00:36,150 --> 00:00:37,440
inside our application.

10
00:00:37,560 --> 00:00:42,170
And let's try to go and see inside the network tab for user operation.

11
00:00:42,420 --> 00:00:50,280
You can see here in the response I have received and header with the name Alteration and it's JWT token

12
00:00:50,460 --> 00:00:58,380
so we can try taking this token and paste in the JWT website to understand what the values that we passed

13
00:00:58,590 --> 00:00:59,760
and based here.

14
00:01:00,090 --> 00:01:03,270
As you can see, the beauty ID card decoded.

15
00:01:03,420 --> 00:01:10,170
Our header has metadata about the algorithm that we have followed and that body has all the values that

16
00:01:10,170 --> 00:01:10,770
we send.

17
00:01:11,250 --> 00:01:18,810
Issuer is the one who issued the token and subject of the token and what are the logged in user name

18
00:01:18,810 --> 00:01:24,600
detail and his rules and authorities associated and ensure that.

19
00:01:24,720 --> 00:01:32,610
What is the issue that you can see how you should act on this date and expiring is going to after three

20
00:01:32,610 --> 00:01:33,060
days.

21
00:01:33,090 --> 00:01:39,780
So now I try to dampen this value on the you way by putting a breakpoint in the interceptor.

22
00:01:39,900 --> 00:01:46,650
So let's try to keep a breakpoint here and making an request to one of the operation.

23
00:01:46,650 --> 00:01:50,580
And you can see this is my JWT token value.

24
00:01:50,820 --> 00:01:57,090
I'm going to just remove one character in the middle and release the breakpoint.

25
00:01:57,090 --> 00:02:06,210
Can see I got an error 500 because there is an exception happen while evaluating this stock.

26
00:02:06,210 --> 00:02:12,910
And on the backend due to that error, I draw an exception and there is no response came to the user.

27
00:02:13,200 --> 00:02:19,510
So this way we can protect our application using JWT tokens.

28
00:02:19,590 --> 00:02:27,810
Now let's try to understand how the expiration of the token will be handled by the spring security framework

29
00:02:27,960 --> 00:02:28,890
in that next world.

30
00:02:28,980 --> 00:02:29,450
Thank you.

31
00:02:29,460 --> 00:02:29,850
And by.
