How did you ensure the security of password storage in your last project?

To ensure the security of password storage in the project, I used the following practices:

• Password hashing: Instead of storing passwords in plain text, cryptographic hashes such as bcrypt or Argon2 were used.
• Use of salt: A unique random salt was added to each password to protect against rainbow table attacks.
• Regular library updates: Up-to-date and verified libraries for hashing were used.

Example in Java using the BCrypt library:

import org.mindrot.jbcrypt.BCrypt;

public class PasswordUtils {
    public static String hashPassword(String plainPassword) {
        return BCrypt.hashpw(plainPassword, BCrypt.gensalt());
    }

    public static boolean checkPassword(String plainPassword, String hashed) {
        return BCrypt.checkpw(plainPassword, hashed);
    }
}

This approach significantly enhances the security of password storage and reduces the risk of data compromise.
