## Email is a Security Risk.

 Sending credentials via support tickets or email leaves a permanent trail. If your server or your client’s email is breached, your secrets are exposed. Our module solves this by moving encryption to the browser.

 ![Create Message](https://www.cloudmill.nl/images/securemessages/Schermafbeelding 2026-03-06 075459.png) Our module uses **AES-256 client-side encryption**. This means the encryption happens in *your* browser. The decryption key is never sent to the server and never stored in the database.

 
- **Client-Side:** You encrypt, the client decrypts. The server is just a carrier.
- **Custom Expiry:** Set links to expire in days, weeks or never.
- **Burn After Reading:** The ultimate safety feature. Self-destruction upon first view.
- **Available in 20+ Languages: ** bulgarian, catalan, chinese, czech, dutch, english, finnish, francais_canada, french, german, greek, indonesia, italian, japanese, norwegian, persian, polish, portuguese, portuguese_br, romanian, russian, slovak, spanish, swedish, turkish, ukrainian, vietnamese

 
## Professional Client Experience

 Your clients don't need an account. They receive a professional, branded link. They enter a password (optional), click 'Show Message', and the data is revealed. Clean, fast, and trustworthy.

 ### White-label

 Matches your Perfex CRM branding, including your logo, company name, and favicon.

## Frequently Asked Questions

 
- ### How secure is the "Message Burner" actually?

 We use **Zero-Knowledge AES-256 encryption**. This means the encryption process happens entirely within your browser before the data is even sent to the server. We never see your plain-text data, and we don't store the decryption keys.
- ### What happens to the data after it "burns"?

 Once a message is viewed (if "Burn-on-read" is enabled) or the expiration timer hits zero, the encrypted record is **permanently deleted** from our database. There are no backups or "recently deleted" folders for burned messages.
- ### Can Cloudmill or my Server Admin read my secrets?

 No. Because the decryption key is part of the URL fragment (the part after the `#`), it is never sent to the server. Even with full database access, an admin only sees an unreadable blob of encrypted characters.
- ### Do I need to configure a Cronjob for the expiration to work?

 Yes. To ensure expired messages are automatically removed, your Perfex CRM Cronjob should be active. The module hooks into the standard Perfex Cron system to perform a "cleanup" every time it runs.
- ### Can I set a password for additional security?

 Absolutely. You can add an optional manual password. The recipient will then need both the unique link AND the password to decrypt the message.
- ### Is there a limit to the length of a message?

 While there is no hard limit, we recommend keeping secrets under 10,000 characters to ensure fast encryption and decryption speeds in the browser.
- ### Can I test the module in the demo?

 Yes! The Cloudmill Showroom is designed to show how our modules work together. You can switch between different Cloudmill extensions directly from the sidebar menu.
- ### Is this a one-time purchase?

 Yes, once you purchase the module via CodeCanyon, you own the license for your Perfex CRM instance. All future updates for that version are included.
- ### Do you provide support for installation?

 Definitely. If you run into any issues during installation or configuration, you can reach out to us at **support@cloudmill.nl**.
