Hướng dẫn cryptography python project

With over 49,889,600 downloads, the Python cryptography library is among the top 100 Python libraries. High-level recipes and simplified gateways to common cryptographic methods, such as symmetrical ciphers, message digests, and key derivation algorithms, are included in this package. It’s now available through the PyPi package management. In this article, we’ll examine how to install the Cryptography package in Python 3 on a Linux machine.

Installing Cryptography package on Linux using PIP

Requirements:

• Python3
• Python3-pip

To install the Cryptography package in Linux follow the following steps:

Step 1: Setting up a Python environment on our Linux operating system. Python3 environment can be ready by executing the below command.

sudo apt-get install python3

Step 2: Installing the PIP manager in our Linux system. PIP manager is officially a module of Python language which can be an assistant for installing various packages. Just execute the below command to install the PIP module.

sudo apt install python3-pip

Step 3: Now using the PIP manager we are going to install the Cryptography package. So for the installation run the following command on the terminal.

sudo pip3 install cryptography 

Verifying the installation of Cryptography package on Linux using PIP

After installing the package, the next important step is to verify the installation of the Cryptography package. So in this step, we are just retrieving the information of the installed package (Cryptography) with the below command on the terminal itself.

python3 -m pip show cryptography 

The below output will be displayed after successful installation of the Cryptography package on your Linux machine.

Project description

cryptography is a package which provides cryptographic recipes and primitives to Python developers. Our goal is for it to be your “cryptographic standard library”. It supports Python 3.6+ and PyPy3 7.2+.

cryptography includes both high level recipes and low level interfaces to common cryptographic algorithms such as symmetric ciphers, message digests, and key derivation functions. For example, to encrypt something with cryptography’s high level symmetric encryption recipe:

>>> from cryptography.fernet import Fernet
>>> # Put this somewhere safe!
>>> key = Fernet.generate_key()
>>> f = Fernet(key)
>>> token = f.encrypt(b"A really secret message. Not for prying eyes.")
>>> token
'...'
>>> f.decrypt(token)
'A really secret message. Not for prying eyes.'

You can find more information in the documentation.

You can install cryptography with:

$ pip install cryptography

For full details see the installation documentation.
