Cryptography Foundations for Computer Science

In modern software development and computer science, understanding how to secure data is no longer optional. This course demystifies cryptography, turning complex mathematical concepts into practical, actionable knowledge. You will transition from a beginner to confidently understanding how cryptographic algorithms work, how to choose the right tools for securing data, and how to avoid common implementation pitfalls. What you'll learn: - Understand foundational cryptographic terms, historical ciphers, and the core concepts of confidentiality, integrity, and authenticity. - Apply symmetric encryption using modern standards like AES to protect data at rest. - Explore asymmetric encryption principles, including RSA and Elliptic Curve Cryptography (ECC), for secure key exchange. - Generate secure cryptographic hashes and implement modern password hashing standards like bcrypt and Argon2. - Analyze secure communication concepts, understanding how TLS/SSL establishes trust over the network. - Avoid common security vulnerabilities by learning best practices for key management and salt generation. This course begins with essential terminology and the mathematical foundations of security before walking you through symmetric and asymmetric algorithms, hashing techniques, and real-world security protocols. It is designed specifically for computer science students, junior developers, and IT enthusiasts seeking a solid, practical introduction to cryptography without needing advanced mathematical prerequisites.
