How can I optimize bcrypt performance in my application?

How can I optimize bcrypt performance in my application?

To optimize bcrypt performance, consider using a lower cost factor, caching hashed passwords, or using a faster hashing algorithm.

What is the cost factor in bcrypt and how does it affect performance?

The cost factor determines the computational complexity of the hashing process. A higher cost increases security but also slows down performance.

Are there any alternatives to bcrypt that offer better performance?

Yes, alternatives like Argon2 or PBKDF2 can offer better performance while still providing strong security.

How do I implement caching for hashed passwords?

You can store hashed passwords in a fast-access storage like Redis, reducing the need to re-hash passwords on every login.
