Digital Shell is a secure document sharing platform that lets professionals send contracts, financial reports, and sensitive files via encrypted, watermarked, trackable links instead of email attachments.
What is Digital Shell?
Digital Shell is a zero-knowledge encrypted file-sharing service designed for confidential client documents. You upload a file (PDF, image, or any document) in your browser, and it is encrypted with AES-256 before leaving your device. The platform generates a secure link and a separate 6-digit access code. The recipient enters the code in their browser to decrypt and view the file — no account required. The product is built by Digital Shell and hosted in the EU and US.
Key Features
- AES-256 encryption — All files are encrypted in your browser before upload; the server never sees plaintext data.
- Expiring, self-destructing links — Set a time limit (1 hour to 30 days) or a view limit (e.g., 1 view). After expiry, the encrypted data is permanently deleted.
- Watermarking — Every viewed copy is tagged with the recipient’s identity (name, email, timestamp). If a document leaks, you can trace the source.
- Detailed access logs — See timestamp, IP address, location (country/city), browser, and device for each view.
- Instant revoke — Stop access to a shared link at any time, even before expiration.
- No recipient account needed — Clients only need the secure link and the 6-digit code sent via a separate channel (e.g., SMS, another email).
Who is it for?
- Attorneys and law firms — Share contracts, case files, and NDA templates with encrypted, watermarked links. Access logs support ABA Rule 1.6 and state bar compliance reviews. Learn more
- CPAs and accountants — Send tax returns, W-2s, and bank credentials via auto-expiring links during tax season. Detailed logs help document controls required by IRS Publication 4557 and the FTC Safeguards Rule. Learn more
- Startups and founders — Share pitch decks and financials with investors while tracking who opens the file and from where. Watermarks deter unauthorized forwarding. Learn more
What can you do with Digital Shell?
- Share confidential documents with clients — Upload a contract, set a 24-hour expiry and watermark, then send the link and code separately. You see when and where it was opened.
- Revoke access mid-session — If a client’s email is compromised, instantly revoke the link. The encrypted data is deleted and the document becomes inaccessible.
- Track document provenance — View logs showing that the file was accessed from Paris on Chrome/macOS or from New York on Safari/iPhone.
How does Digital Shell work?
- You upload a document in your browser. It is encrypted with AES-256 before being sent to Digital Shell’s servers.
- A secure link and a 6-digit access code are generated. You copy the link and send the code separately (e.g., via text message).
- The recipient clicks the link, enters the code, and the file is decrypted in their browser. The recipient’s identity is watermarked onto the viewed document.
- You see a live activity log: “Link accessed — Paris, FR — Chrome — macOS — 2s ago.”
