Wormhole Private Encrypted File Sharing

Wormhole is a browser-based tool that enables secure, end-to-end encrypted file transfers up to 10 GB without requiring registration. All files are encrypted with AES-128-GCM in the browser and can be sent via peer-to-peer WebRTC or temporarily stored on Wormhole’s servers for 24 hours before automatic deletion. The service generates a unique link (including the decryption key in the URL fragment) that expires after one day, ensuring zero-knowledge privacy—only sender and recipient can access the content. With native mobile apps and CLI support, Wormhole caters to both casual users and power users seeking a fast, private alternative to email attachments or third-party cloud storage.

How to Use

1. Open your browser and navigate to the official site: https://wormhole.app .

2. Click “Select files to send” and choose up to 10 GB of data.

3. Once the encryption completes, copy the generated link (it contains the decryption key in the fragment).

4. Share the link via chat, email, or QR code. The recipient simply opens it in their browser to download.

5. Files remain available for 24 hours before permanent deletion.

6. For command-line transfers, install the Wormhole CLI (npm install -g wormhole-cli) and run wormhole send <file> to get a code or link.

Features

• End-to-End Encryption: All files encrypted client-side with AES-128-GCM; Wormhole servers never see unencrypted data.

• Automatic Expiry: Shared links self-destruct after 24 hours; files are erased from servers to protect privacy.

• Up to 10 GB Transfers: Generous size limit without requiring user accounts; ideal for large media and datasets.

• Peer-to-Peer & Server Fallback: Preferential WebRTC transfer for speed and privacy, with server relay if direct connection fails.

• No Account Needed: Zero registration lowers friction; simply open the site or use CLI to share instantly.

• Cross-Platform Support: Works in any modern browser; native apps on Android/iOS; CLI tool for Linux/macOS/Windows.

• Open Source: Security design and implementation are publicly auditable on GitHub under BSD-3 Clause license.

Suitable Scenarios

• Ad-hoc Large File Sharing: Send videos, design files, or datasets without cloud account setup.

• Confidential Data Exchange: Share contracts, legal documents or personal archives with end-to-end encryption.

• Remote Collaboration: Quickly distribute builds, prototypes or large assets to distributed teams.

• Travel & Field Work: Transfer media from mobile devices in areas with intermittent connectivity using the app.

• Command-Line Workflows: Integrate Wormhole CLI into scripts and CI/CD pipelines for automated file delivery.
