We will look at different use cases and learn how encryption and cryptanalysis work. This book is a fascinating journey to one of the most secret and unknown skill. Every chapter includes hands-on practices. It is written for beginners and intermediate users.

When do we use cryptography?
We actually use it just about anywhere. We use it when we send messages, When we speak over IP, When we connect to a secure web server over HTTPS. We use it in our Wi-Fi to secure our Wi-Fi traffic. Digital life and cryptography​ are combined together for the last 40 years, and of the most dominant use cases for using cryptography within the last 30 years is definitely our SmartPhones.

When we use voice calls, our data is ​ encrypted.
When we store data in our smartphones, it is ​ encrypted​.
When we browse web sites, the connection nowadays is usually ​ encrypted.

Why do we encrypt everything? For two main reasons:
