Secure Password Storage with Hashing and Salting

In an era of frequent data breaches, storing passwords in plain text is a critical security vulnerability. Understanding how to securely hash and salt passwords is an essential skill for any backend developer. This text-only course guides you through the fundamental mechanics of cryptographic hashing, salting, and key stretching. You will understand how to defend against common attacks like rainbow tables and brute-force attempts, implementing modern industry-standard algorithms in your own applications. What you'll learn: Understand the core differences between encryption, encoding, and cryptographic hashing; Apply unique salts to passwords to prevent precomputed rainbow table attacks; Configure modern hashing algorithms such as bcrypt, PBKDF2, and Argon2 with appropriate work factors; Implement secure verification workflows to authenticate users safely during login; Identify common password storage pitfalls and how to avoid them in backend development. You will start with foundational cryptography concepts and definitions before moving on to practical implementation strategies and code-based scenarios. By studying written explanations and clear code snippets, you will learn how to design a robust authentication backend from scratch. This course is designed for beginner developers and security enthusiasts with a basic understanding of programming concepts; no prior cryptography experience is required.
