1
00:00:01,710 --> 00:00:08,680
End to end encryption happens when the data is encrypted by the sender and only decrypted by the recipient.

2
00:00:08,870 --> 00:00:15,690
This is a desired form encryption for data in transit for maximum protection of the data.

3
00:00:15,900 --> 00:00:23,400
If you wish to avoid tracking global mass surveillance hackers and so on the use of HTP security on

4
00:00:23,430 --> 00:00:29,620
all web sites is becoming increasingly important regardless of the type of data that is being sent.

5
00:00:29,850 --> 00:00:36,420
As we go into more details on how tracking mass surveillance and browser hacking happens you will understand

6
00:00:36,420 --> 00:00:39,660
more and more the importance of encryption.

7
00:00:39,750 --> 00:00:49,040
Examples of encryption technology includes things like PGE P S MIME o TR which is off the record or

8
00:00:49,050 --> 00:00:56,770
Zed or TR which is zed in real time transport protocol as well as SSL and TLR.

9
00:00:56,820 --> 00:01:04,740
Implemented in the right way those can be and and companies that develop software that use and encryption

10
00:01:04,860 --> 00:01:11,150
and zero knowledge systems cannot reveal the details of the communication to your adversary.

11
00:01:11,280 --> 00:01:14,370
Even if coerced even if they wanted to.

12
00:01:14,370 --> 00:01:19,390
That is the benefit of encryption with zero knowledge.

13
00:01:19,590 --> 00:01:26,610
Examples of this type of software throughout the course but Examples include the messaging software

14
00:01:26,760 --> 00:01:31,450
signal chat secure crypto care and others.

15
00:01:31,470 --> 00:01:37,560
If everyone used and encryption for all traffic everyone's traffic would look the same when only some

16
00:01:37,560 --> 00:01:39,540
people use N10 encryption.

17
00:01:39,540 --> 00:01:46,210
Those people that use it into an encryption standard is different and encryption offers protection in

18
00:01:46,220 --> 00:01:50,180
transit but obviously does not offer protection for data.

19
00:01:50,270 --> 00:01:57,200
Once it is received you needed different protection mechanism to use and turn encryption wherever possible.
