1
00:00:00,450 --> 00:00:03,760
So where is this where we're going to take a look at this tool called openness.

2
00:00:04,230 --> 00:00:11,040
And this is very important for cryptography and this is mainly used for establishing the secure connection

3
00:00:11,040 --> 00:00:12,630
between the sender and receiver.

4
00:00:13,050 --> 00:00:18,710
And it's also helpful in generating the certificates and public and private keepsakes as well.

5
00:00:19,530 --> 00:00:27,690
So it supports a lot of encryption data and we can safely and pretexting to continue to do ciphertext.

6
00:00:28,950 --> 00:00:29,490
So.

7
00:00:31,580 --> 00:00:41,900
We need to take both the necessary and then sorest safer comments, so this will restart the same for

8
00:00:41,900 --> 00:00:48,940
comments I can execute, uh, to create the ciphertext and you can see the famous algorithms.

9
00:00:49,010 --> 00:00:49,680
Yes.

10
00:00:50,120 --> 00:00:58,780
Uh, this and base64, this is not an option, but we can just get the all put into this bill 64.

11
00:00:59,570 --> 00:01:06,530
So now let's go and try this Bill 64, including first, let me say open sister.

12
00:01:08,810 --> 00:01:19,310
So this openness will operate on Phylis, so let me try to file with the content, say hello world,

13
00:01:20,600 --> 00:01:23,960
and this is our plain text message and let's.

14
00:01:26,360 --> 00:01:33,620
I read this into the file complaint, so no brain file contains this horrible text.

15
00:01:35,030 --> 00:01:43,550
So what we're going to do is we are going to say open and Sissel and we need to Switchfoot and Yansi.

16
00:01:43,550 --> 00:01:48,420
And afterwards we will discuss further encryption algorithm that's be 64.

17
00:01:48,470 --> 00:01:57,440
You need to switch for hyphen to indicate this as an option like argument and encryption base64.

18
00:01:57,740 --> 00:02:03,490
And we need to switch with the input so sane and take the plain text file the display.

19
00:02:04,820 --> 00:02:07,250
No, we have got this output.

20
00:02:07,710 --> 00:02:09,350
This is the basis for output.

21
00:02:09,830 --> 00:02:15,350
Now you can sell this with the out option out to cipher.

22
00:02:17,090 --> 00:02:20,210
Now, if you take a look at this, conditions are the same for.

23
00:02:21,930 --> 00:02:24,990
You will have this same ciphertext.

24
00:02:27,080 --> 00:02:29,090
Now, let me go and decode this.

25
00:02:29,390 --> 00:02:36,630
Oh, base64, uh, text that's open SSL and encryption matter.

26
00:02:36,650 --> 00:02:42,750
I want to use this basically for what I need to specify the way that is the Modeste.

27
00:02:42,920 --> 00:02:50,050
I want to know right now if I stay in and I want to listen for the input, but now I'm going to switch

28
00:02:50,120 --> 00:02:54,800
the encryption with each and I would decrypt from the input cipher.

29
00:02:55,820 --> 00:02:58,240
And as you can see, we got the output as well.

30
00:02:58,880 --> 00:03:01,490
No, let's go ahead and try one of these.

31
00:03:01,610 --> 00:03:02,130
Uh, yeah.

32
00:03:02,180 --> 00:03:02,450
Yes.

33
00:03:02,450 --> 00:03:02,920
Algorithm.

34
00:03:03,230 --> 00:03:05,390
Let's say you want to do it with CBC.

35
00:03:05,400 --> 00:03:08,210
More open.

36
00:03:10,800 --> 00:03:13,020
So the issue here.

37
00:03:15,330 --> 00:03:22,420
So I'm going to use this encryption method you want to deal with on the plane takes the control.

38
00:03:23,400 --> 00:03:25,690
Now it's going to ask for the password.

39
00:03:25,710 --> 00:03:29,120
So this is yes, we need to do the password.

40
00:03:29,190 --> 00:03:33,030
Senechal and we need to interrogate.

41
00:03:36,480 --> 00:03:44,700
So if you take a look at this, uh, so far, you'll get some random characters, it says it started

42
00:03:45,000 --> 00:03:51,480
so random value has been added to the encryption to make sure that the decryption is somewhat difficult

43
00:03:51,480 --> 00:03:52,470
for attackers.

44
00:03:53,820 --> 00:04:03,690
So now what we're going to do is we are going to encrypt this whole in 64, you can pass multiple encryption.

45
00:04:03,700 --> 00:04:10,050
So after this one so fast, it will take the text and it will apply the algorithm and then it will apply

46
00:04:10,060 --> 00:04:12,110
the basic algorithm.

47
00:04:12,170 --> 00:04:16,910
Now, if you hit enter, tell the password again at the.

48
00:04:18,900 --> 00:04:28,380
So if you take a look at the server, you have this base64 and so on, you'll get this one and you need

49
00:04:28,380 --> 00:04:30,160
to decrypt this user.

50
00:04:31,830 --> 00:04:35,740
So this is the basic user of using the algorithm, Sylvanus.

51
00:04:36,450 --> 00:04:40,580
Now let's go ahead and generate our second page.

52
00:04:40,770 --> 00:04:46,810
So we run this RSA from the cryptography fundamentals and now we are going to generate the public and

53
00:04:46,810 --> 00:04:47,580
the private key.

54
00:04:48,980 --> 00:04:58,400
And I want to open, as I said, janoris it to join Dieser and say our protests keep.

55
00:05:01,670 --> 00:05:11,720
So this KEEPON file contains both private and public and to specify the keirin letter to 048, which.

56
00:05:14,630 --> 00:05:20,930
So as you can see, generating RSA, private key Pajero for a week long mudras to Prem's, so we have

57
00:05:20,960 --> 00:05:27,920
already know that there will be two Pym's PNU in this area and the evalu 650 Tresa.

58
00:05:28,790 --> 00:05:33,880
And remember, we are certain some basic are sensitive and we have solved it.

59
00:05:34,940 --> 00:05:44,750
So if you take a look at this people and you can see there is only the private key, so by default we

60
00:05:44,750 --> 00:05:45,710
cannot see the public.

61
00:05:45,830 --> 00:05:48,510
We need to extract the public key from this one.

62
00:05:49,310 --> 00:06:01,630
So you need to do open SSL, you need to say RSA and then Adesina to specify in the input for this Kieber

63
00:06:02,270 --> 00:06:05,390
file and then you need to set up about.

64
00:06:09,580 --> 00:06:13,460
So we are just extracting this from this keep it.

65
00:06:14,200 --> 00:06:16,590
So this is the private key and this is the public.

66
00:06:16,840 --> 00:06:20,890
So one important thing to remember is this.

67
00:06:20,890 --> 00:06:29,440
Arissa is used in, as I said to his generation, and then you will see some private key that is stored

68
00:06:29,440 --> 00:06:36,400
in this home for the DOD is a directory in that if you find any private key of any other user of the

69
00:06:36,400 --> 00:06:42,400
router user, you can just if you have the right access, then you can just copy it into the file and

70
00:06:42,400 --> 00:06:47,680
you can use that as a search command to interact with these private key without entering the password.

71
00:06:47,980 --> 00:06:53,010
So that is one of these misconfiguration you see in this next section.

72
00:06:53,710 --> 00:06:56,210
So we have just excited the public.

73
00:06:56,980 --> 00:07:05,110
So one thing I want to show you in this kitchen is I want to say so on this text, I get the ah the

74
00:07:05,110 --> 00:07:07,800
detailed information about this, uh, file.

75
00:07:09,700 --> 00:07:15,850
So as you can see, there is a modulus and we have already seen this in our research and public experience.

76
00:07:15,970 --> 00:07:21,100
So it is on and private explorer, which is the right B?

77
00:07:21,130 --> 00:07:22,850
I think so, yes, I think so.

78
00:07:22,900 --> 00:07:23,440
It should be.

79
00:07:23,680 --> 00:07:26,410
And this is called a C no, I don't know.

80
00:07:26,560 --> 00:07:28,210
It's just a modulus.

81
00:07:28,210 --> 00:07:35,410
And after the private exponent is B and the prime, I want to be and do and this exponent one and two

82
00:07:36,100 --> 00:07:37,030
and the coefficient.

83
00:07:37,510 --> 00:07:46,690
So these are the parameters that are involved in Adisa and corruption and the crucial public and private

84
00:07:46,690 --> 00:07:47,100
keeper.

85
00:07:48,880 --> 00:07:51,470
So this is what this is.

86
00:07:52,000 --> 00:07:57,150
And you can also, uh, encrypt here.

87
00:07:57,160 --> 00:08:01,060
You can say and trip and you can specify that any other.

88
00:08:01,060 --> 00:08:01,460
Idato.

89
00:08:01,480 --> 00:08:06,950
You can, uh, even encrypt this private key to some years or this format.

90
00:08:09,640 --> 00:08:16,270
So the thought about this openness and lastly, I want to show you the open SSL, so we have learned

91
00:08:16,270 --> 00:08:25,930
about this 80 percent default rate so we can generate the encrypted password and we can edit that is

92
00:08:25,930 --> 00:08:28,000
suitable for the possibility encryption.

93
00:08:28,990 --> 00:08:34,020
And this possibility uses the best algorithm for encrypting the passwords.

94
00:08:34,510 --> 00:08:39,020
I didn't know Tuesdays open as a possibility and indiscernible.

95
00:08:40,480 --> 00:08:44,100
So the password, Nikil, will be encrypted.

96
00:08:45,250 --> 00:08:51,610
So now you can push this in a two party preferred username, then you can put this in group.

97
00:08:53,170 --> 00:09:02,590
So if you want to specify some sort for this, so it will be like only for this username and password

98
00:09:04,030 --> 00:09:06,070
or to make it secure.

99
00:09:08,220 --> 00:09:14,970
And you can just I have added the salt for this username and password, this encrypted possibility for

100
00:09:14,970 --> 00:09:23,810
the username and password, and you can see the username here and this can be copied into the Tea Party.

101
00:09:24,240 --> 00:09:31,170
When you have the right access, you can just add another user with this password hash so that what

102
00:09:31,230 --> 00:09:32,540
this openness is available.

103
00:09:33,000 --> 00:09:34,200
I hope you have understood.
