Cryptography Algorithms

By: Massimo Bertaccini

Overview of this book

Cryptography Algorithms is designed to help you get up and running with modern cryptography algorithms. You'll not only explore old and modern security practices but also discover practical examples of implementing them effectively. The book starts with an overview of cryptography, exploring key concepts including popular classical symmetric and asymmetric algorithms, protocol standards, and more. You'll also cover everything from building crypto codes to breaking them. In addition to this, the book will help you to understand the difference between various types of digital signatures. As you advance, you will become well-versed with the new-age cryptography algorithms and protocols such as public and private key cryptography, zero-knowledge protocols, elliptic curves, quantum cryptography, and homomorphic encryption. Finally, you'll be able to apply the knowledge you've gained with the help of practical examples and use cases. By the end of this cryptography book, you will be well-versed with modern cryptography and be able to effectively apply it to security applications.

Introduction to asymmetric encryption

The most important function of private/public key encryption is exchanging a key between two parties, along with providing secure information transactions.

To fully understand asymmetric encryption, we must understand its background. This kind of cryptography is particularly important in our day-to-day lives. This is the branch of cryptography that's deputed to cover our financial secrets, such as credit cards and online accounts; to generate the passwords that we use constantly in our lives; and, in general, to share sensitive data with others securely and protect our privacy.

Let's learn a little bit about the history of this fascinating branch of cryptography.

The story of asymmetric cryptography begins in the late 1970s, but it advanced in the 1980s when the advent of the internet and the digital economy started to introduce computers to family homes. The late 1970s and 1980s was the period in which Steve Jobs founded Apple...
