00:00:00,930 --> 00:00:04,600
Hello and welcome to this lecture.

2
00:00:05,280 --> 00:00:13,000
In this lecture hall we'll be looking at the differences between Hage TTP and he.

3
00:00:13,020 --> 00:00:25,910
T T P S hates T T P stands for hypertext transfer to call it is secure.

4
00:00:25,920 --> 00:00:38,280
B H T T P with the s is the secured version of the d t t P E T T P E which is a product for use to transport

5
00:00:38,340 --> 00:00:46,120
data from your web browser and the website to we you are connected to.

6
00:00:46,500 --> 00:00:49,110
So the s at the end of the page.

7
00:00:49,110 --> 00:00:52,730
T T P S stands for secure.

8
00:00:52,920 --> 00:00:56,460
So where you see the S in a t t P.

9
00:00:56,490 --> 00:01:04,770
No there is a secured connection which means all the communication between your web browser and that

10
00:01:04,770 --> 00:01:07,920
website is encrypted.

11
00:01:08,550 --> 00:01:17,670
So this is an illustration of how the T T P E and he t t p s works.

12
00:01:17,670 --> 00:01:20,530
So this is a user here.

13
00:01:20,550 --> 00:01:29,670
See I assume this is me and hi on my browser and send in some information.

14
00:01:29,670 --> 00:01:33,110
True a connection that is not secure.

15
00:01:33,330 --> 00:01:34,920
So does this pipe here.

16
00:01:34,920 --> 00:01:36,020
This is a protocol.

17
00:01:36,030 --> 00:01:40,830
This is his TTP which means a connection is not secured.

18
00:01:41,120 --> 00:01:52,290
And normally that connection past strew port 80 port 80 is the TTP port that transports insecure connection

19
00:01:53,130 --> 00:01:55,960
on this side of the coin.

20
00:01:56,040 --> 00:02:01,390
There is a secured connection where you are using his t t p s.

21
00:02:01,540 --> 00:02:11,960
The data is encrypted means it is safe and it transports the data true is secured.

22
00:02:12,120 --> 00:02:22,790
Connection port so Port 443 is usually secured that will be the port used to transport encrypted connection

23
00:02:23,140 --> 00:02:35,190
and sometimes this requires s s s l l certificate the s s l l certificate are like small data files

24
00:02:35,640 --> 00:02:45,300
that digitally bind a cryptographic key to your companys details so when they are installed on a web

25
00:02:45,300 --> 00:02:55,230
server and this activity you can see it padlock next to the hit TTP is protocol over at the port in

26
00:02:55,230 --> 00:02:56,950
which he transported data.

27
00:02:56,970 --> 00:02:59,090
Thus the pulled 44 3.

28
00:02:59,130 --> 00:03:07,950
So this allows secure connection from a web server or via that browser where there is he secure connection.

29
00:03:08,510 --> 00:03:12,180
Ah I thought this is the same home page here.

30
00:03:12,240 --> 00:03:22,690
So if you notice here we've got the t t p s sign here which means that it is a secure connection so

31
00:03:22,720 --> 00:03:24,640
it is Haiti t p s.

32
00:03:24,820 --> 00:03:29,890
Let's refresh that again.

33
00:03:33,350 --> 00:03:37,240
And that should go to you Jamie.

34
00:03:37,460 --> 00:03:44,490
All right so you can see you the ME has gone hate t t p s secure collection.

35
00:03:44,930 --> 00:03:47,290
Okay.

36
00:03:47,720 --> 00:03:53,670
And this is a Web site without hate TTP has connection.

37
00:03:53,670 --> 00:03:55,130
So if I type in

38
00:03:57,840 --> 00:04:00,620
a t t p without the S

39
00:04:03,560 --> 00:04:06,080
and that takes me to one squirrel dot com.

40
00:04:06,260 --> 00:04:08,080
So this hasn't gotten here.

41
00:04:08,090 --> 00:04:09,290
T T P S.

42
00:04:09,440 --> 00:04:10,580
So disconnect shan't.

43
00:04:10,580 --> 00:04:12,620
E less secured.

44
00:04:12,620 --> 00:04:23,010
So most connections you have with online banking or any site that requires high security or be using

45
00:04:23,090 --> 00:04:26,800
a secure connection of up board 443.

46
00:04:26,960 --> 00:04:36,540
So just remember that football 443 is a secure connection while port 80 is not in this video.

47
00:04:36,540 --> 00:04:49,130
We learnt deep differences between hastey t p and his t t p s s in Haiti T P indicate a secured connection

48
00:04:49,640 --> 00:04:54,890
without the s incy connection is not secured secured connection.

49
00:04:54,890 --> 00:05:01,020
Chance file their data or transport data VI is secured port 44.

50
00:05:01,040 --> 00:05:02,120
3.

51
00:05:02,140 --> 00:05:05,250
Why are the insecure connection transport data.

52
00:05:05,270 --> 00:05:09,690
True in no more t.t. port which is port 80.

53
00:05:09,980 --> 00:05:12,120
Thank you so much for your time.

54
00:05:12,350 --> 00:05:13,080
Bye for now.
