1
00:00:00,150 --> 00:00:04,650
Now will create an empty matrix to store the deciphered message.

2
00:00:04,890 --> 00:00:16,620
So here we create these cipher SDR that's equal to blank initially and then we run on the score in the

3
00:00:16,860 --> 00:00:31,960
range rule your run using the DC cipher, SD card use plus is equal to none multiplied by the columnist

4
00:00:31,980 --> 00:00:34,860
here close Closed-in Square brackets.

5
00:00:35,160 --> 00:00:42,390
And then we would arrange the Matrix while the column was according to the permutation order by adding

6
00:00:42,390 --> 00:00:43,680
into one new matrix.

7
00:00:44,010 --> 00:00:50,850
So here again, we would run four on the score in the range of now columnist.

8
00:00:52,920 --> 00:01:02,130
And here we see the current variable for current current current Ebix, we have you that is equal to

9
00:01:02,130 --> 00:01:09,000
the key is still not use the index in bracket.

10
00:01:09,030 --> 00:01:14,170
The key list that you have created, the bracket colonoscope idea.

11
00:01:15,870 --> 00:01:24,790
And after this, we create another for loop ciggy, one in the range of your role here.

12
00:01:24,840 --> 00:01:35,910
We use the DC Cipher SDR at the index G1 and the second index as current index.

13
00:01:36,300 --> 00:01:48,390
That's equal to we use the message enlistee index of message index and here we say the message index

14
00:01:49,530 --> 00:01:52,350
plus is equal to one.

15
00:01:52,800 --> 00:01:55,260
And here we see the key.

16
00:01:55,420 --> 00:01:59,160
The score index is plus is equal to one.

17
00:01:59,730 --> 00:02:05,680
Now, once we have done this, we will have to convert the decrypted message matrix into spring.

18
00:02:06,150 --> 00:02:13,980
So for that, we would go one level back and say, you're right, give here the value, say, MSJ,

19
00:02:14,140 --> 00:02:20,670
SDR, that's equal to blank dot veals join in bracket.

20
00:02:20,670 --> 00:02:33,480
We give the sum of the easy, say, Forestier, comma square brackets and then we say here, except

21
00:02:33,870 --> 00:02:48,000
the type error call we are raising here, the type error c c this program cannot

22
00:02:51,750 --> 00:02:52,410
handle

23
00:02:54,720 --> 00:02:56,330
repeating votes.

24
00:02:57,140 --> 00:03:07,830
Close it and then we create herea null count that's equal to our message is still to count the underscore

25
00:03:07,830 --> 00:03:10,440
value and check.

26
00:03:10,560 --> 00:03:18,840
If your null count is more than zero then we are saying return the message.

27
00:03:18,840 --> 00:03:28,330
SDR using the string as minus null on the school or college in the school bracket.

28
00:03:28,710 --> 00:03:35,340
Now once you have completed this, don't forget to return the value of message and once that is done,

29
00:03:35,340 --> 00:03:38,120
we return the value of message SDR.

30
00:03:38,610 --> 00:03:51,780
Here we will create MSDS star value and we are giving here the code as C this is fighting hacking message

31
00:03:52,320 --> 00:03:54,080
and here we are first.

32
00:03:54,120 --> 00:03:59,130
Calling the encrypt a star is a variable that we have created.

33
00:03:59,520 --> 00:04:04,890
Where we are calling the encrypt message is still passing.

34
00:04:04,890 --> 00:04:07,050
The MSDS are variable there.

35
00:04:07,560 --> 00:04:12,480
Then we are printing the value of encrypt astar variable.

36
00:04:13,440 --> 00:04:23,190
We again create or decrypt star wherein we are calling the decrypt message A and now we are passing

37
00:04:23,190 --> 00:04:29,730
in this the encryption because whatever is encrypted, the same thing we are supposed to decrypt and

38
00:04:29,730 --> 00:04:33,440
then we are printing here the value of decrypt hestia.

39
00:04:34,020 --> 00:04:45,090
Let us save this in the same folder by the name say demo sixteen, not by and let us try to run the

40
00:04:45,090 --> 00:04:45,570
module.

41
00:04:46,140 --> 00:04:50,910
Now that is let's see on line number seven first.

42
00:04:51,030 --> 00:04:57,210
So let's go back here and let's go to line number seven.

43
00:04:58,690 --> 00:05:05,910
Or that is a lie, as Steve made a mistake, their gear still is not defined online.

44
00:05:05,920 --> 00:05:07,530
No, it's fine.

45
00:05:09,250 --> 00:05:12,640
So here we have defined Kirsti of.

46
00:05:15,280 --> 00:05:20,630
Metaphors are in asteroidal, a spelling mistake, line number sixty four.

47
00:05:20,950 --> 00:05:31,810
Let's go to line sixty four and this is why beating again, let us run the module site.

48
00:05:31,810 --> 00:05:33,790
Forestier is not defined.

49
00:05:33,910 --> 00:05:37,510
That is line number torpedos.

50
00:05:39,590 --> 00:05:44,930
So we are having here, say, Asgeir, not the.

51
00:05:46,130 --> 00:05:47,570
Let's give it a run.

52
00:05:48,290 --> 00:05:53,750
So this is how it has been encrypted and the same text has been taken for Decrypt, and this is the

53
00:05:53,750 --> 00:05:59,360
original message that we have written, which is passed on to encrypted, encrypted, and this message

54
00:05:59,360 --> 00:06:03,960
is passed on to decrypt to get back your original message.

55
00:06:04,460 --> 00:06:10,970
So likewise, we have done another demonstration wherein we have combined both the files together for

56
00:06:10,970 --> 00:06:13,340
encrypting it and for decrypting it.

57
00:06:13,520 --> 00:06:20,630
So if you now try to import this file that we have, for example, the more 16 in another file and you

58
00:06:20,630 --> 00:06:25,130
want to use both the encryption decrypt methods is quite possible.

59
00:06:25,260 --> 00:06:30,050
So you don't need to import two different files, just import one file that is the most exciting.

60
00:06:30,290 --> 00:06:38,910
And using them all 16 dot encrypt messages start for encrypting it and demo 16 for dot decrypt messages

61
00:06:39,230 --> 00:06:43,000
for decrypting a particular message and getting the value written.

62
00:06:43,190 --> 00:06:49,220
Hence we are returning this value every so that you can save it in another variable like this and print

63
00:06:49,220 --> 00:06:51,100
it wherever you're using it.

64
00:06:51,590 --> 00:06:52,980
So that's it from the session.

65
00:06:53,000 --> 00:06:53,930
Thank you very much.
