This module focuses on practical encryption techniques and how they are implemented to protect data across systems. You will explore different types of encryption, including full-disk, file, and transport encryption, and understand their real-world applications. The module also introduces Public Key Infrastructure (PKI), including certificate authorities, trust models, and key management. Additionally, you will examine security hardware such as TPM and HSM, along with obfuscation techniques like steganography, with hands-on practice using OpenSSL and CrypTool.

This module explores advanced cryptographic concepts used to ensure data integrity, authentication, and trust. You will learn how hashing algorithms like MD5 and SHA work and apply them using OpenSSL. The module also covers digital signatures and their role in verification, along with blockchain fundamentals and real-world applications. Additionally, you will examine digital certificates, OCSP, and certificate management practices, gaining practical experience in creating and validating secure identities.

This module consolidates your learning by applying cryptographic concepts in a practical, scenario-based project. You will implement encryption techniques to secure data, ensure authentication, and enable verification in a simulated environment. The module also reinforces key concepts from across the course and prepares you to apply cryptography skills in real-world cybersecurity contexts.
