Password Hashing (bcrypt)

Never store plain-text passwords. Hash them with a salt.

Overview

Never store plain-text passwords. Hash them with a salt.

Code Example

import bcrypt from "bcrypt";\nconst hash = await bcrypt.hash("myPassword", 10);\nconst match = await bcrypt.compare("myPassword", hash);

Web Development Context

In modern web development, understanding Password Hashing (bcrypt) is crucial. Node.js is widely used for building APIs, real-time applications, and microservices. Mastery of this concept allows you to build efficient, scalable, and secure backend systems.

Common Mistakes

• Blocking the event loop with heavy synchronous tasks.
• Exposing secrets in code instead of environment variables.
• Forgetting to handle promise rejections.
