How can PHP developers implement client-side encryption using tools like OpenPGP.js to enhance security when handling sensitive data like passwords?

Client-side encryption using tools like OpenPGP.js can enhance security by ensuring that sensitive data, such as passwords, is encrypted on the client-side before being sent to the server. This means that even if the server is compromised, the data remains encrypted and secure. PHP developers can implement client-side encryption by integrating OpenPGP.js into their web applications and using it to encrypt sensitive data before sending it to the server. 

// PHP code snippet to implement client-side encryption using OpenPGP.js

// Include OpenPGP.js library
<script src="https://cdnjs.cloudflare.com/ajax/libs/openpgp/4.10.10/openpgp.min.js"></script>

// Generate a new OpenPGP key pair for the user
$key = \OpenPGP::generate_key([
    "comment" => "User Key",
    "passphrase" => "user_passphrase"
]);

// Encrypt sensitive data (e.g., password) using the user's public key
$encrypted_data = \OpenPGP::encrypt([
    "data" => "sensitive_data_to_encrypt",
    "public_key" => $key["public_key"]
]);

// Send the encrypted data to the server for storage
// Make sure to securely store the user's private key on the client-side
