Secure Password Storage with Cryptographic Hashing and Salting

Storing user passwords in plain text or using outdated encryption is one of the most critical security vulnerabilities a developer can introduce. Understanding how to securely hash and salt passwords is essential for protecting user data from database breaches. This text-based course guides you through the fundamental principles of cryptography applied to credential storage. You will learn how to transition from insecure practices to modern, industry-standard hashing algorithms, ensuring your applications remain resilient against offline brute-force attacks. What you'll learn: • Understand the core differences between encryption, encoding, and cryptographic hashing. • Apply unique salts and pepper values to mitigate rainbow table and precomputation attacks. • Implement slow hashing algorithms like bcrypt, PBKDF2, and Argon2 with appropriate work factors. • Configure secure storage workflows to defend against credential stuffing and brute-force attempts. • Analyze database breach scenarios to identify and fix common storage vulnerabilities. Starting with foundational concepts of cryptography and hashing functions, this course guides you step-by-step through practical implementation strategies and configuration choices. You will read clear explanations, analyze secure code examples, and practice your skills through written design exercises. This course is designed for beginner developers, aspiring security analysts, and system administrators with no prior cryptography experience.
