Encrypted lockers for secure client communication and file sharing.

Locker Features

• Individual Client Lockers: Each client gets a unique, password-protected, secure area
• Secure File Sharing: Upload and download encrypted files with full privacy
• Message Thread: Secure, timestamped communication log between lawyer and client
• Activity Audit Trail: Track all locker access, file downloads, and messages
• No Client Accounts Required: Share a simple URL with encryption key in the fragment

Lockbox Features

• One-offs: One-time encrypted messages that self-destruct after reading
• End-to-End Encryption: All data is encrypted in the browser using AES-256-GCM before transmission
• Zero-Knowledge Server: The server never has access to encryption keys or plaintext data
• No Client Accounts Required: Share a simple URL with encryption key in the fragment

How it Works

1. Lawyer creates a locker in WordPress admin
2. Plugin generates a unique URL with encryption key (/locker/abc123/#encryption-key)
3. Lawyer shares this URL securely with their client
4. Both parties access the locker using the same URL
5. All messages and files are encrypted/decrypted locally in the browser
6. Server only stores encrypted blobs (no plaintext ever touches the server)

Security Notice

The encryption key is included in the URL fragment (after the #). This must be shared securely:

• Use encrypted email (Proton)
• Use secure messaging (Signal)
• Use the built-in Lockbox feature
• Share in-person or via phone
• DO NOT send via regular email (Gmail, Yahoo, Hotmail) or SMS

Perfect For

• Law firms managing sensitive client communications
• Accountants sharing financial documents
• Healthcare providers (HIPAA compliance considerations)
• Politicians and government officials
• Journalists and activists
• Anyone requiring genuine privacy and confidentiality

Technical Details

• Uses Web Crypto API for browser-based AES-256-GCM encryption
• Custom database tables for encrypted files and activity logs
• No third-party dependencies
• Clean, minimal codebase

Browser Requirements

• Modern browser with Web Crypto API support (all current browsers)
• JavaScript must be enabled (required for encryption/decryption)
