<ul>
<li>Admin form to generate <code>share_url</code> and token via API.</li>
<li>Option to replace all sent emails (<code>wp_mail</code>) with a secure link (attachments are removed).</li>
<li>Customizable placeholders in the email body: <code>{share_url}</code>, <code>{token}</code>, <code>{max_views}</code>, <code>{expire_minutes}</code>.</li>
<li>Support for optional password, expiration in minutes, and Markdown/HTML flags.</li>
<li>Configurable endpoint (default <code>https://cryptnote.pro/api/v1</code>) and optional <code>X-API-Key</code> header.</li>

<h3>Privacy</h3>
This plugin uses the external CryptNote service to generate and host the secure link and token. When creating a link, the protected content and metadata (views, expiration, optional password) are sent to <code>https://cryptnote.pro/api/v1</code>. See the service’s privacy policy at https://cryptnote.pro/privacy.php?lang=en.

Encrypted lockers for secure client communication and file sharing.
Locker Features
<ul>
<li>Individual Client Lockers: Each client gets a unique, password-protected, secure area</li>
<li>Secure File Sharing: Upload and download encrypted files with full privacy</li>
<li>Message Thread: Secure, timestamped communication log between lawyer and client</li>
<li>Activity Audit Trail: Track all locker access, file downloads, and messages</li>
<li>No Client Accounts Required: Share a simple URL with encryption key in the fragment</li>
</ul>
Lockbox Features
<ul>
<li>One-offs: One-time encrypted messages that self-destruct after reading</li>
<li>End-to-End Encryption: All data is encrypted in the browser using AES-256-GCM before transmission</li>
<li>Zero-Knowledge Server: The server never has access to encryption keys or plaintext data</li>
<li>No Client Accounts Required: Share a simple URL with encryption key in the fragment</li>
</ul>
How it Works
<ol>
<li>Lawyer creates a locker in WordPress admin</li>
<li>Plugin generates a unique URL with encryption key (<code>/locker/abc123/#encryption-key</code>)</li>
<li>Lawyer shares this URL securely with their client</li>
<li>Both parties access the locker using the same URL</li>
<li>All messages and files are encrypted/decrypted locally in the browser</li>
<li>Server only stores encrypted blobs (no plaintext ever touches the server)</li>
</ol>
Security Notice
The encryption key is included in the URL fragment (after the #). This must be shared securely:
<ul>
<li>Use encrypted email (Proton)</li>
<li>Use secure messaging (Signal)</li>
<li>Use the built-in Lockbox feature</li>
<li>Share in-person or via phone</li>
<li>DO NOT send via regular email (Gmail, Yahoo, Hotmail) or SMS</li>
</ul>
Perfect For
<ul>
<li>Law firms managing sensitive client communications</li>
<li>Accountants sharing financial documents</li>
<li>Healthcare providers (HIPAA compliance considerations)</li>
<li>Politicians and government officials</li>
<li>Journalists and activists</li>
<li>Anyone requiring genuine privacy and confidentiality</li>
</ul>
Technical Details
<ul>
<li>Uses Web Crypto API for browser-based AES-256-GCM encryption</li>
<li>Custom database tables for encrypted files and activity logs</li>
<li>No third-party dependencies</li>
<li>Clean, minimal codebase</li>
</ul>
Browser Requirements
<ul>
<li>Modern browser with Web Crypto API support (all current browsers)</li>
<li>JavaScript must be enabled (required for encryption/decryption)</li>
</ul>
