What are the best practices for password hashing?

The best practices for password hashing include using a strong hashing algorithm like bcrypt, scrypt, or Argon2, adding a unique salt for each password, and ensuring the hash is stored securely.

Why is it important to use a salt when hashing passwords?

Using a salt prevents attackers from using precomputed hash tables (rainbow tables) to crack passwords, as each password hash will be unique.

How do I choose the right hashing algorithm?

Choose a hashing algorithm that is widely recognized and recommended for security, such as bcrypt, scrypt, or Argon2, which are designed to be slow and resistant to brute-force attacks.

What should I do if my database of hashed passwords is compromised?

If your database is compromised, you should immediately invalidate all passwords, require users to reset their passwords, and consider implementing additional security measures like two-factor authentication.
