How do I use bcrypt for password hashing?

You can use bcrypt in your application by installing the bcrypt library. In Node.js, for example, you can install it using npm: npm install bcrypt. Then, you can hash a password like this: bcrypt.hash(password, saltRounds, function(err, hash) { ... });.

What are salt rounds, and how do I choose them?

Salt rounds determine the complexity of the hashing process. More rounds mean more security but also more time to hash. A common choice is 10-12 rounds.

Can I compare a plain password with a hashed one?

Yes, you can use bcrypt.compare(plainPassword, hash, function(err, result) { ... }); to check if the plain password matches the hashed one.

Is bcrypt the best option for password hashing?

Bcrypt is a popular choice due to its adaptive nature, but other algorithms like Argon2 are also highly recommended for their security features.
