How To Install python3-cryptography on Kali Linux

In this tutorial we learn how to install python3-cryptography on Kali Linux. python3-cryptography is Python library exposing cryptographic recipes and primitives (Python 3)

Introduction

In this tutorial we learn how to install python3-cryptography on Kali Linux.

What is python3-cryptography

python3-cryptography is:

The cryptography library is designed to be a “one-stop-shop” for all your cryptographic needs in Python.

As an alternative to the libraries that came before it, cryptography tries to address some of the issues with those libraries:

  • Lack of PyPy and Python 3 support.
  • Lack of maintenance.
  • Use of poor implementations of algorithms (i.e. ones with known side-channel attacks).
  • Lack of high level, “Cryptography for humans”, APIs.
  • Absence of algorithms such as AES-GCM.
  • Poor introspectability, and thus poor testability.
  • Extremely error prone APIs, and bad defaults.

This package contains the Python 3 version of cryptography.

There are three methods to install python3-cryptography on Kali Linux. We can use apt-get, apt and aptitude. In the following sections we will describe each method. You can choose one of them.

Install python3-cryptography Using apt-get

Update apt database with apt-get using the following command.

sudo apt-get update

After updating apt database, We can install python3-cryptography using apt-get by running the following command:

sudo apt-get -y install python3-cryptography

Install python3-cryptography Using apt

Update apt database with apt using the following command.

sudo apt update

After updating apt database, We can install python3-cryptography using apt by running the following command:

sudo apt -y install python3-cryptography

Install python3-cryptography Using aptitude

If you want to follow this method, you might need to install aptitude on Kali Linux first since aptitude is usually not installed by default on Kali Linux. Update apt database with aptitude using the following command.

sudo aptitude update

After updating apt database, We can install python3-cryptography using aptitude by running the following command:

sudo aptitude -y install python3-cryptography
