Implementing Cryptography Using Python

Introduction

I initiated my journey into cryptography while studying for my undergrad. Most of the cryptography concepts I learned were based on what one would need for their CISSP or Security+ exams. Most of my understanding was at a high level, and it was difficult to remember the more intricate aspects until cryptography became a primary focus.

It wasn't until I started my master's in cybersecurity that I began applying cryptographic features within a scripting environment. The concepts in this book will help you advance your knowledge and experience as you dig deeper into understanding the use of cryptography in Python.

Over the past few years, several governments have discussed legislation that will ensure that any form of communication, whether it's an email, text message, or video chat, can always be read by the police or intelligence services if they have a warrant. Governments are putting pressure on technology companies to give them backdoor access or the keys to the kingdom so that they can keep the country safe.

The fight between lawmakers and encrypted messaging platforms has entered new territory. Imagine a world where the government has seized the opportunity to scan every electronic message by government-approved scanning software. The privacy and security of all users will suffer if law enforcement agencies achieve their dream of breaking cryptosystems. Proponents of end-to-end encryption, like Microsoft, Facebook, and Google, may lose their campaign to maintain ...
