How can the issue of truncated hash values in MySQL databases be addressed when using md5() for password hashing?

When using md5() for password hashing in MySQL databases, the issue of truncated hash values can be addressed by ensuring that the column in the database where the hash is stored has a long enough length to accommodate the full md5 hash value. This will prevent any data loss or truncation of the hash value. 

// Example code snippet to create a table in MySQL with a column long enough to store full md5 hash values
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// SQL query to create a table with a column for storing md5 hash values
$sql = "CREATE TABLE users (
id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
username VARCHAR(30) NOT NULL,
password VARCHAR(32) NOT NULL
)";

if ($conn->query($sql) === TRUE) {
    echo "Table users created successfully";
} else {
    echo "Error creating table: " . $conn->error;
}

// Close connection
$conn->close();
