Secure Password Hashing with bcrypt in Rails APIs

Security is a critical foundation of any web application, especially when building APIs that handle sensitive user data. This written course guides you through the process of securing user passwords using industry-standard hashing algorithms. You will learn to implement robust authentication mechanisms that protect user accounts from unauthorized access. What you'll learn: - Understand the fundamentals of cryptography, password hashing, and salting. - Configure the bcrypt gem within a modern Rails API environment. - Implement the has_secure_password macro to automate password protection. - Build secure registration and authentication endpoints for client applications. - Apply modern API security practices, including safe CORS configurations and secure headers. - Practice writing clean, testable authentication logic with step-by-step code examples. You will start with foundational security concepts before moving step-by-step through configuring Rails, writing database migrations, and testing your secure API endpoints. This course is designed for beginner Rails developers and API designers with a basic understanding of Ruby. No prior security experience is required. Start building secure Rails APIs today.
