Inline Decryptor

About

This extension reveals text that has been encrypted with a per-URL password, directly on 
the page. Encrypted messages (for example on a forum) are decrypted locally and shown as 
readable text, without the password ever entering the web page.

Features:- Per-URL passwords in a local, encrypted vault (AES-GCM).- A single master password unlocks the vault; the master password is never stored.- Automatic locking after a set time and when you are away.- Encrypt and decrypt text yourself via a separate window.- Export and import an encrypted backup, protected with a password you choose.- Dutch and English interface.
Privacy:- Fully offline. No data is collected, shared, or sent to any server.- No account, no tracking, no ads.- All data stays encrypted on your own device.
Key derivation with PBKDF2 (SHA-256, 310,000 iterations) and AES-GCM 256-bit encryption, 
entirely in the browser

example with php:
 Encrypt_Function.php:
<?php
function encryptData($text, $wachtwoord) {
    $key = hash('sha256', $wachtwoord, true);
    $iv = openssl_random_pseudo_bytes(12);
    $tag = ""; 
    
    $encrypted = openssl_encrypt($text, 'aes-256-gcm', $key, OPENSSL_RAW_DATA, $iv, $tag);
    $output = base64_encode($iv . $tag . $encrypted);
    
    return "<encrypt-tekst-excrypt>" . $output . "</encrypt-tekst-excrypt>";
}
?>

settings.php:
<?php
$wachtwoord = "mijn-geheime-wachtwoord";
?>
