Applied Cryptography for Cyber Security

In an era of constant data breaches, securing sensitive information is the foundation of any robust security strategy. This text-based course demystifies the concepts behind cryptography and translates them into practical, real-world security practices. You will transition from understanding basic security concepts to confidently selecting, configuring, and implementing modern cryptographic systems. By reading clear explanations and working through practical scenarios, you will learn how to protect data at rest, in transit, and in use. What you'll learn: - Explain foundational cryptographic concepts, including confidentiality, integrity, non-repudiation, and authentication. - Implement symmetric and asymmetric encryption algorithms to secure sensitive data. - Apply secure hashing functions and digital signatures to verify data integrity and authenticity. - Configure modern secure key exchange protocols and manage digital certificates within a public key infrastructure (PKI). - Understand modern cryptographic trends, including contemporary TLS configurations and the basics of post-quantum cryptography. - Identify and mitigate common cryptographic implementation vulnerabilities and design flaws. The course begins with essential terminology and the historical foundations of secret-sharing, then guides you step-by-step through modern algorithms, protocol design, and practical deployment considerations. This course is designed for beginners in IT, system administration, or software development who want to build a strong foundation in cryptography without needing an advanced math background.
