How does the choice of hashing algorithm, such as Whirlpool, impact the security of password storage in a MySQL database when using PHP?

Using a strong hashing algorithm like Whirlpool can significantly improve the security of password storage in a MySQL database. Whirlpool is a cryptographic hash function that produces a fixed-size 512-bit hash value, making it more resistant to brute force attacks compared to weaker algorithms like MD5 or SHA-1. By using Whirlpool in combination with salting and key stretching techniques, you can enhance the security of stored passwords in your MySQL database. 

// Hashing password using Whirlpool algorithm
$password = "user_password";
$salt = openssl_random_pseudo_bytes(32); // Generate a random salt
$hash = hash('whirlpool', $password . $salt); // Hash password with salt using Whirlpool algorithm

// Store hashed password and salt in MySQL database
// Make sure to properly sanitize and validate user input before storing in the database
