How do you use password hashing (PBKDF2, etc

Password hashing is an essential technique used to securely store user passwords. This involves transforming the actual password into a hashed version using algorithms like PBKDF2, bcrypt, or Argon2. Here, we will provide an example of how to use PBKDF2 for hashing passwords in PHP.


        <?php
        // Define a password and a salt
        $password = "user_password";
        $salt = "random_salt"; // In practice, use a secure random value

        // Hash the password using PBKDF2
        $hash = hash_pbkdf2("sha256", $password, $salt, 100000); // 100,000 iterations
        echo "Hashed password: " . $hash;
        ?>
