4 Awesome Python Libraries for Cryptography

Python programming is best known for its simplicity and general-purpose programming language. As a general-purpose programming language python have global acceptance in the tech world. 

Python programming language is best known for the libraries. These libraries are provided by the python community whether it is built-in or created by the community as third-party libraries.

Either way, there are always some python libraries that will make your day by importing the code of the library. You just have to import the functionality from the library. And the rest of the work is done by the method provided by the Libraries. 

Python provides awesome Libraries for cryptography as well. Cryptography is important sometimes even an essential part of programming. we need to know about these python libraries for cryptography.

What is Cryptography?

Cryptography is the study of secure communications techniques that allow only the sender and intended recipient of a message to view its contents. With the help of cryptography, data is encrypted using a secret key, and then both the encoded message and secret key are sent to the recipient for decryption.

1. cryptography

cryptography is the most beautiful and well-documented python library for cryptography. as the name suggests this is a widely used Python library for cryptography purposes in the python programming language.

It is the easy-to-use python library for cryptography. if you are a beginner and looking for a cryptography library. then give it a shot as this is the easiest python library as I mentioned earlier. cryptography includes high-level recipes and low-level interfaces to common cryptographic algorithms such as symmetric cyphers, message digests, and key derivation functions.

2. Paramiko

ParamikoParamiko” is a combination of the Esperanto words for “paranoid” and “friend”. It’s a module for Python 2.7/3.4+ that implements the SSH2 protocol for secure (encrypted and authenticated) connections to remote machines. Unlike SSL (aka TLS), the SSH2 protocol does not require hierarchical certificates signed by a powerful central authority.

You may know SSH2 as the protocol that replaced telnet and ssh for secure access to remote shells, but the protocol also includes the ability to open arbitrary channels to remote services across the encrypted tunnel (this is how SFTP works, for example).

It is written entirely in Python (though it depends on third-party C wrappers for low-level crypto; these are often available precompiled) and is released under the GNU Lesser General Public License (LGPL). The package and its API are well documented in the docs folder that should have come with this repository.

3. Passlib

It is a password hashing library for Python 2 and 3, which provides cross-platform implementations of over 30 password hashing algorithms, as well as a framework for managing existing password hashes. It’s designed to be useful for a wide range of tasks, from verifying a hash found in /etc/shadow to providing full-strength password hashing for multi-user applications.

4. pynacl

PyNaCl is a Python binding to libsodium, which is a fork of the Networking and Cryptography library. These libraries have a stated goal of improving usability, security, and speed. It supports Python 3.5+ as well as PyPy 3.

Some of the best features of PyNaCl are Digital signatures, Secret-key encryption, Public-key encryption, Hashing and message authentication, Password-based key derivation, and password hashing.

Summary and Conclusion:-

These are python libraries that can help you in your next cryptographic project. Links to each project are provided. Please feel free to ask any questions you have in mind.
