Password Security Fundamentals: From Plain Text to Modern Hashing

Storing user passwords in plain text is one of the most dangerous security vulnerabilities a system can have. Understanding how to transition from insecure storage to robust cryptographic protection is a fundamental skill for any developer or system administrator. By reading this text-only course, you will gain a clear understanding of secure password management and learn how to safeguard user credentials against modern threats. What you will learn: 1. Understand the critical risks of plain text password storage and common attack vectors. 2. Learn the fundamental differences between encryption, encoding, and cryptographic hashing. 3. Apply modern salting techniques to protect against rainbow table attacks. 4. Implement secure hashing algorithms like bcrypt and Argon2 for robust credential protection. 5. Discover zero-trust principles and how they apply to authentication systems. 6. Practice evaluating password storage mechanisms for potential vulnerabilities. This course starts with essential security terminology and foundational definitions before guiding you through the concepts of modern hashing standards. It is designed for beginning developers, system administrators, and security enthusiasts with no prior cryptography or security experience.
