How does password hashing (PBKDF2, etc

Password hashing is a crucial practice in securing user passwords. By using algorithms like PBKDF2, bcrypt, or Argon2, we can transform plain text passwords into a secure format that is difficult to reverse-engineer. This process involves applying a hashing function along with a unique salt and multiple iterations to enhance security against brute force attacks.

Example of Password Hashing with PBKDF2


        <?php
        $password = 'your_secure_password';
        $salt = openssl_random_pseudo_bytes(16);
        $hashedPassword = hash_pbkdf2('sha256', $password, $salt, 10000);
        
        echo "Salt: " . bin2hex($salt) . "<br>";
        echo "Hashed Password: " . $hashedPassword;
        ?>
