00:00:04,970 --> 00:00:07,880

Authentication mechanisms.



2

00:00:09,050 --> 00:00:09,660

Hi, everyone.



3

00:00:09,730 --> 00:00:16,010

Today, we're going to talk about authentication and I will explain what it is and then we're going



4

00:00:16,010 --> 00:00:22,470

to, of course, do some python tests and write the scripts in order to do authentication with Python.



5

00:00:22,760 --> 00:00:33,050

I guess some of you might know some things about authentication, but the most simple way to expand



6

00:00:33,050 --> 00:00:40,460

is, for example, sometimes if you want to log into your account, you will need an authentication



7

00:00:40,460 --> 00:00:45,290

app in order for you to have to have verification of yourself.



8

00:00:45,320 --> 00:00:51,470

So this is a more secure way to assess your Web, credit those over the Web or over the network.



9

00:00:51,920 --> 00:01:01,700

Authentication supports natively HTP protocols and intercepts, both types of basic HTP and that they



10

00:01:01,700 --> 00:01:02,910

just htp.



11

00:01:03,410 --> 00:01:15,230

So the basic HTP authentication is based on the Base 64 protocol and usually is composed by two things



12

00:01:15,290 --> 00:01:17,100

user and password.



13

00:01:17,120 --> 00:01:18,910

And this is your username and password.



14

00:01:19,130 --> 00:01:24,920

You know, you can always see your passport written by dots, so you cannot actually see what you're



15

00:01:24,920 --> 00:01:25,310

writing.



16

00:01:25,550 --> 00:01:32,420

So the authentication mechanism is just the way that you're seeing Callcredit those and it defines what



17

00:01:32,420 --> 00:01:34,640

is password, what's its user username and so on.



18

00:01:34,910 --> 00:01:39,680

The other HTP mechanism for authentication is the HTP.



19

00:01:39,680 --> 00:01:40,790

They just mechanism.



20

00:01:41,000 --> 00:01:49,430

And this mechanism used in the five encryption protocols to encrypt the user details with Python, it



21

00:01:49,430 --> 00:01:56,150

is actually very easy to access authentication modules and you can do this usually with the request,



22

00:01:56,160 --> 00:02:03,180

the library, and from there you can access both the basic and they just authentication algorithms.



23

00:02:03,710 --> 00:02:07,450

So let's first talk about the basic authentication.



24

00:02:07,670 --> 00:02:16,390

The best way to out the indication assumes that the client is identified only by username and password.



25

00:02:16,790 --> 00:02:22,850

So in order for the client to assess the website or the page over the web, he needs to provide both



26

00:02:22,850 --> 00:02:25,140

of those great docs and in order to do that.



27

00:02:25,520 --> 00:02:34,040

So once you request a server to log in, the server usually responds with the connection to the base64



28

00:02:34,040 --> 00:02:42,260

encoding and gives you the fields where you can write your credit or as we said, username and password



29

00:02:42,890 --> 00:02:43,760

on their site.



30

00:02:43,760 --> 00:02:51,200

The date just authentication is created after the base authentication and is usually used to improve



31

00:02:51,200 --> 00:02:57,440

and it usually encrypts all the information with an algorithm code and give five.



32

00:02:57,740 --> 00:03:05,510

It was a key and the rail in order to encrypt your data so that they just authentication extends the



33

00:03:05,510 --> 00:03:13,680

basic one by using one way hashing cryptographic algorithm in order to protect your credit those.



34

00:03:14,330 --> 00:03:21,960

So it first encrypts the authorization information and then it adds a unique connecting value.



35

00:03:22,590 --> 00:03:31,790

This value is used by the client browser in order to calculate the possible response in a hash format.



36

00:03:32,390 --> 00:03:38,120

So your password is not directly related to you, but needs to be calculated by the algorithm in the



37

00:03:38,120 --> 00:03:38,570

return.



38

00:03:39,080 --> 00:03:41,760

This extra level of safety.



39

00:03:42,020 --> 00:03:43,740

Why are we using Callcredit those?



40

00:03:43,880 --> 00:03:50,750

So this was the introduction to the authentication mechanisms in the in the next lecture, we're going



41

00:03:50,750 --> 00:03:52,370

to assess them by using Python.



42

00:03:52,700 --> 00:03:53,130

That's it.



43

00:03:53,150 --> 00:03:57,470

Guys, thanks very much for watching this video and I'll be waiting for you in the next one.
