Learn to evaluate and compare data encryption methods and attack cryptographic systems

Key Features

• Explore popular and important cryptographic methods
• Compare cryptographic modes and understand their limitations
• Learn to perform attacks on cryptographic systems

Book Description

Cryptography is essential for protecting sensitive information, but it is often performed inadequately or incorrectly.

Hands-On Cryptography with Python starts by showing you how to encrypt and evaluate your data. The book will then walk you through various data encryption methods,such as obfuscation, hashing, and strong encryption, and will show how you can attack cryptographic systems. You will learn how to create hashes, crack them, and will understand why they are so different from each other. In the concluding chapters, you will use three NIST-recommended systems: the Advanced Encryption Standard (AES), the Secure Hash Algorithm (SHA), and the Rivest-Shamir-Adleman (RSA).

By the end of this book, you will be able to deal with common errors in encryption.

What you will learn
