A Beginner’s Guide to Python Encryption

Get started with encryption in Python using the cryptography library

Encryption is the process of converting plain text into a coded message to protect its confidentiality. It is a fundamental concept in computer security and is used to secure sensitive data such as passwords, credit card numbers, and other personal information. Encryption is achieved by using an algorithm to transform the original message into an unreadable format, which can only be deciphered by someone who has the key to unlock it.

In this blog post, we will explore the basics of encryption and how to use the cryptography library to implement it in Python. We will cover both symmetric and asymmetric encryption, as well as hashing. We will also provide practical guidance and code examples to help readers understand how to use the cryptography library for encryption in Python.
