3 Best Python Encryption Libraries in 2022

Python is a powerful programming language that is widely used in many industries today. In fact, Python is one of the most popular programming languages in the world. Because of its popularity, there are many libraries available to help developers encrypt data using Python. In this blog post, we will discuss some of the best Python encryption libraries available today. We will also discuss the pros and cons of each library. By the end of this blog post, you will know which Python encryption library is best for your needs.

What Is Data Encryption?

Data encryption is the process of transforming readable data into an unreadable format. This is done in order to protect the data from being accessed by unauthorized individuals. Data encryption is a very important security measure that should be used whenever sensitive data is being stored or transmitted.

There are many different algorithms that can be used for data encryption. The most popular algorithm is the Advanced Encryption Standard (AES). AES is a symmetric-key algorithm, which means that the same key is used for both encryption and decryption.

Why Do We Need An Encryption Library?

We need an encryption library because the Python standard library does not provide any built-in encryption functions. This is a security measure to make sure that developers do not accidentally write insecure code. If you want to encrypt data using Python, you must use an external library.

There are many advantages to using encryption.

First and foremost, encryption protects your data from being accessed by unauthorized individuals. This is very important, especially if you are storing sensitive data. Encryption also helps to ensure the privacy of your data. Additionally, encryption can help to prevent data breaches. If your data is encrypted, it will be much more difficult for attackers to access it.

Finally, encryption can also be used to verify the integrity of your data. This is because encrypted data can be mathematically verified. This means that you can be sure that your data has not been tampered with.

What Are The Best Python Encryption Libraries?

PyCryptodome

PyCryptodome, a fork of PyCrypto that brings enhanced security and performance to your Python applications, is the swiss army knife of Python cryptography. It’s perfect for prototyping and production applications alike. With PyCryptodome, you’ll have everything you need to keep your data safe and sound.

This comprehensive package provides everything you need to get started with low-level cryptography. Whether you’re using Python 2.7, 3.5, or PyPy, PyCryptodome has you covered.

PyCryptodome features authenticated encryption modes (GCM, CCM, EAX, SIV, OCB), accelerated AES on Intel platforms via AES-NI, first-class support for PyPy, elliptic curves cryptography (NIST curves P-192, P-224, P-256, P-384, and P-521), and much more.

With support for a wide range of cryptographic algorithms, PyCryptodome is ideal for everything from securing communications to protecting data. And because it uses cutting-edge truncated hash algorithms like SHA-512/224 and SHA-512/256, you can be confident that your data is safe and secure. 

Criptography

If you’re looking for a cryptographic package that provides both high-level recipes and low-level interfaces to common algorithms, try Criptography. The goal of this package is to be your go-to “cryptographic standard library”, and it supports Python 3.6+ and PyPy3 7.2+.

It supports a variety of security features, including authenticated encryption, asymmetric algorithms, constant time functions, key derivation functions, key wrapping, message authentication codes, message digests (hashing), symmetric encryption, symmetric padding, and two-factor authentication. It also supports Fernet and X.509.

With Criptography, you can easily encrypt data with symmetric ciphers, message digests, and key derivation functions. Its high-level recipes make it easy to get up and running quickly.

PyNaCl

Introducing PyNaCl, the Python binding to libsodium. This powerful library is a fork of the Networking and Cryptography library, and it offers significant improvements in usability, security and speed. PyNaCl supports Python 3.6+ as well as PyPy 3.

With PyNaCl, you can take advantage of digital signatures, secret-key encryption, public-key encryption, hashing and message authentication, and password-based key derivation and password hashing. This makes PyNaCl the perfect choice for a wide range of applications requiring secure communications and data protection.
