Implementing Secure Password Hashing in Node.js

Storing passwords securely is one of the most critical responsibilities of any backend developer. Simple encryption is no longer enough to protect user data from modern security threats. In this course, you will learn how to implement robust password storage mechanisms in Node.js using industry-standard hashing algorithms. You will transition from understanding basic cryptographic concepts to writing secure, production-ready hashing code. What you'll learn: - Understand the fundamental difference between encryption and cryptographic hashing. - Identify the security vulnerabilities of legacy algorithms like MD5 and SHA-1. - Implement secure password hashing using BCrypt and Argon2 in Node.js applications. - Apply salting and peppering techniques to defend against rainbow table attacks. - Configure work factors and resource limits to resist hardware-accelerated brute-force attempts. - Align your authentication workflows with modern security standards and OWASP recommendations. The course begins with foundational cryptographic definitions and the history of password storage. You will then progress through step-by-step written explanations and code implementations to build a secure authentication flow. This course is designed for beginner backend developers and security enthusiasts. No prior cryptography experience is required, though a basic familiarity with JavaScript and Node.js is helpful.
