Password Encryption and Security in Ruby

Securing user passwords is one of the most critical responsibilities for any web developer. This text-based course guides you through the fundamental principles of cryptography and password hashing within the Ruby ecosystem. You will transition from storing plain-text passwords to implementing robust, production-ready encryption techniques. By understanding how to leverage Ruby's built-in libraries and modern industry standards, you will prevent unauthorized access and protect sensitive user data. What you'll learn: - Understand the fundamental differences between encryption, hashing, and encoding. - Apply the Ruby digest library to generate secure SHA2 cryptographic hashes. - Implement salting and key stretching to protect against rainbow table attacks. - Compare traditional hashing algorithms with modern, adaptive standards like BCrypt. - Configure safe password verification workflows within your Ruby applications. Starting with essential security terminology, you will progress through structured text lessons and practical code examples. You will read, analyze, and write clean Ruby scripts that handle sensitive authentication data securely. This course is designed for beginner Ruby developers who want to build a solid foundation in application security without needing any prior cryptography experience.
