This book is designed to teach students how to analyze and deploy cryptography in the real world. The reader will learn the history of cryptography and how to break several historical cyphers using Python. The reader will then learn additional methods that are strong enough to withstand real attacks. The book will teach the reader how to create secure communications in public channels using public-key cryptography. The reader will explore methods of authenticating messages to ensure that they haven't been tampered with in transit. They will then explore the use of digital signatures that lets others verify that messages were sent by an individual. | Implementing Cryptography Using Python by Shannon W.
