friends Hello everyone, you are on the

00:00:10

pythontoday channel and today we will write

00:00:13

three projects with less than 10 lines of code

00:00:16

each, all the code from the video as well as links

00:00:18

to the libraries used can be found in

00:00:21

our Telegram channel Subscribe

00:00:23

the link will be in the description Today we

00:00:26

will learn how to encrypt files, which is very

00:00:28

It’s important to carry out hidden

00:00:30

password entry and also extract an audio track from a

00:00:33

video file, which for me personally turned out to be

00:00:36

very useful, especially in conjunction with a

00:00:38

telegram bot. You throw a

00:00:40

video file into the Bot and it gives you an easy

00:00:43

audio podcast that you can listen to

00:00:45

even on the plane, while driving, or while

00:00:48

jogging. it is important What program you

00:00:51

wrote A bot or a full-fledged website,

00:00:54

sooner or later you will have to

00:00:57

deploy any project on a server First vds is a

00:00:59

large hosting provider that has been on

00:01:02

the market for 20 years. On December 6, the guys started

00:01:06

celebrating their anniversary. In honor of this holiday,

00:01:08

they launched a cool promotion, what will happen on

00:01:12

December 6 There will be discounts, entertaining

00:01:15

statistics for clients, a raffle for

00:01:18

Apple equipment and the Festrunner game, the First

00:01:21

Runner game was created by the developers

00:01:23

specifically for the 20th anniversary of the VDS Fest,

00:01:26

participants are invited to help Fez John

00:01:28

run from slow 2002 to

00:01:31

super fast 2022 Play, look for

00:01:35

Easter eggs, enter the top and receive

00:01:38

additional gifts for each client

00:01:41

who plays the game, you have

00:01:43

the opportunity to win a MacBook iPhone

00:01:45

PlayStation or certificates for the balance

00:01:48

VDS Fest will be waiting for everyone on the

00:01:51

promotion page from December 6th to 13th,

00:01:54

join via the link in the description

00:01:57

Okay, let's start by extracting the audio track, the

00:02:00

wonderful Movie Pie module will help us with this,

00:02:02

install it in Our

00:02:04

virtual environment By the way,

00:02:06

the possibilities of the field are essentially limitless when

00:02:09

working with media files. You can not

00:02:12

only extract audio tracks, but also, for

00:02:14

example, Trim a video to the required

00:02:16

moments, compress files several times

00:02:18

without actually losing quality, and even

00:02:21

work with subtitles. Let’s import the

00:02:23

Editor module from movipie.

00:02:27

First of all, we’ll specify module What

00:02:29

file does it need to work with

00:02:31

[music]

00:02:33

We turn to the videofileclip class and in the

00:02:37

parameters We pass the path to our file

00:02:39

in my case the file is located next to the

00:02:42

executable script So I’ll just

00:02:43

pass the name then we get the audio track

00:02:47

from the file by referring to the dio attribute

00:02:49

if we look under the hood then we will see that

00:02:52

this is an object of the class audio-file clip. The

00:02:55

last thing we have to do is

00:02:58

save the audio track file. We turn to the

00:03:01

file method in the parameter of which

00:03:03

we pass the name of the file,

00:03:08

we try to run the script

00:03:15

[music]

00:03:18

and Voila next to the executable file. We

00:03:22

have an audio file. We are testing,

00:03:28

we wanted to solve the problem with using the library

00:03:31

Okay, the next thing we need to do is if

00:03:33

you have more experience in working with this

00:03:35

library

00:03:39

Okay, let's set the necessary one, get the

00:03:43

file name using the Stem property. Everything is ok.

00:03:46

Yes, we could write code that takes

00:03:48

the name of the video file and creates an audio file

00:03:51

With the same name, let's correct

00:03:54

this with that Moreover, this will only add a couple of

00:03:56

lines of code, but I think it will be very useful.

00:03:59

We import the PAZ class from the pas sleep module

00:04:04

and get the path to our video file,

00:04:09

then we pass the path to the video file class

00:04:12

as before,

00:04:16

but for the name of the audio file we use the

00:04:19

properties of the walls, which takes only

00:04:22

the name but discards it extension,

00:04:24

rename the video file,

00:04:31

run a script

00:04:45

that will take two parameters,

00:04:48

display the original file name and everything

00:04:52

is ok, the next program we will

00:04:54

write will encrypt files with text using the

00:04:57

symmetric NPP block cipher algorithm,

00:05:01

you can read more about this algorithm in Google in

00:05:04

Python there is a wonderful and

00:05:06

very popular one for this pyascript module

00:05:09

install it

00:05:15

import first

00:05:19

ask the user for a

00:05:21

password yes As you already know, the

00:05:24

Input function allows us to temporarily

00:05:26

pause the execution of the program and

00:05:28

waits while the user enters data

00:05:30

showing the data itself in the terminal for

00:05:33

securely entering a password in Python there is a

00:05:35

special function that we will

00:05:37

look at in the next program So

00:05:39

watch the video to the end, first of all, let's

00:05:42

encrypt the file, create the file itself with

00:05:45

some random text

00:05:48

and call the module's encrypt file method

00:05:52

in the parameter of which, as the first argument,

00:05:54

we pass the file that we want to

00:05:56

encrypt, then the name of the encrypted

00:05:59

file on the output

00:06:02

and the last argument we specify the password,

00:06:05

try to run script,

00:06:08

enter the password

00:06:12

and get the encrypted file

00:06:25

Now let's decrypt it just as

00:06:28

simply,

00:06:31

this time we use the

00:06:33

decrypt-file method first. Pass the path to the

00:06:36

encrypted file, then the path to the

00:06:39

files where the data will be written

00:06:42

and of course the password,

00:06:48

run the script,

00:06:50

enter the password

00:06:54

and get the data file of course this is

00:06:57

not all that this module can do, a

00:06:59

link to documentation and other examples

00:07:01

of work, I will leave in our Telegram channel the

00:07:04

next program that we will write

00:07:07

will encrypt PDF files, install the

00:07:09

pipdf module in our virtual

00:07:12

environment

00:07:14

and import from it two classes

00:07:18

PDF file Writer

00:07:20

and PDF Reader file

00:07:23

we create class objects in the pdf file Writer

00:07:27

and PDF file Reader

00:07:32

in which we pass the path to the PDF file with

00:07:35

which we will work in our

00:07:37

directory, I saved one, then we

00:07:39

need to get all the pages of the file,

00:07:41

use the for loop, go through the

00:07:44

pages

00:07:46

and Using the at page method we read and

00:07:49

add each page,

00:07:52

then we need to request a password for

00:07:55

encryption and let's just use the

00:07:59

getpass function specially designed for this from the module of the same name,

00:08:02

import,

00:08:07

create a password variable

00:08:11

and pass the getpass function using the

00:08:13

PROMT method a hint for the user

00:08:16

when entering after we encrypt the file using the

00:08:19

crypt methods in parameter of which

00:08:21

We pass the password, we have to write

00:08:24

the file, use the context manager UIZ,

00:08:27

open the file for writing in binary

00:08:29

mode [music]

00:08:31

and write using the Write method

00:08:34

called on the pdf-filewriter object,

00:08:38

in principle, everything is ready Let's

00:08:41

test, run the script,

00:08:45

enter the password Please note that the input is

00:08:48

not shown in the

00:08:50

Enter terminal and next to the original file

00:08:53

We now have a password-protected file,

00:08:55

let’s try to open it, we

00:08:58

intentionally enter the wrong password and

00:09:00

get an error, enter the correct one

00:09:04

and we have access to the file, our code

00:09:08
