Master Cryptography with Python: From History to Real-World Implementation.

Key Features
● Learn by building encryption algorithms and secure systems using Python.
● Master everything from basic ciphers to advanced cryptographic solutions.
● Develop the ability to identify and address vulnerabilities in encryption systems.

Book Description
Cryptography is the backbone of modern digital security, and Python makes it accessible for everyone. Hands-on Cryptography with Python takes readers from foundational concepts to advanced cryptographic systems, equipping them with both theoretical understanding and practical implementation skills using Python.

You’ll begin with setting up the platform and Installation and move on to understanding the basics of cryptography—exploring classic ciphers, their evolution, and their role in secure communication. Next, you’ll advance to Symmetric Key Cryptography and Asymmetric Key Cryptography, learning how to implement encryption algorithms step-by-step with Python.

As you progress, you’ll dive into essential cryptographic components like Hashing and Message Integrity, enabling you to safeguard data and verify its authenticity. The book then introduces miscellaneous cryptographic schemes and highlights the principle that “Security is Only as Strong as the Weakest Link”, encouraging you to identify and address vulnerabilities.

Toward the final stages, you’ll gain hands-on expertise in TLS Communication, the backbone of secure data exchange on the web. The journey culminates with an exploration of current trends in cryptography, including lightweight cryptography and post-quantum solutions, ensuring you stay ahead in this ever-evolving field.
