What are the potential pitfalls of using ssh2_auth_pubkey_file in PHP?

One potential pitfall of using ssh2_auth_pubkey_file in PHP is that it may expose sensitive information, such as private keys, if not handled securely. To mitigate this risk, it is important to ensure that the private key file is stored securely and access is restricted to authorized users only. Additionally, regularly monitor and rotate keys to minimize the impact of potential breaches. 

<?php
// Load private key securely
$privateKey = file_get_contents('/path/to/private_key');
chmod('/path/to/private_key', 0600);

// Authenticate using public key
if (ssh2_auth_pubkey_file($connection, $username, '/path/to/public_key', $privateKey)) {
    echo "Authentication successful";
} else {
    echo "Authentication failed";
}
?>
