What are the differences between popular password hashing algorithms?

Popular password hashing algorithms include bcrypt, Argon2, PBKDF2, and scrypt. Each has unique features like security strength, speed, and memory usage.

Can you explain how bcrypt works?

Bcrypt uses a key stretching technique to make it computationally intensive to crack passwords. It incorporates a salt to protect against rainbow table attacks.

What makes Argon2 different from bcrypt?

Argon2 is designed to be memory-hard, making it resistant to GPU-based attacks. It also allows customization of memory, time, and parallelism.

Which algorithm is the most secure?

Argon2 is currently considered the most secure due to its resistance to various attack vectors and its flexibility in configuration.

How do I choose the right algorithm for my application?

Consider factors like security requirements, performance, and the environment in which your application will run. Argon2 is a great choice for new applications.
