Wormhole.app

Yes, Wormhole is designed with security and privacy in mind. All files are end-to-end encrypted using 128-bit AES-GCM encryption before leaving your browser. Wormhole cannot read your files, and no one else can either. Files are permanently deleted from the server after 24 hours.

For files up to 5 GB, Wormhole stores your files on its servers for 24 hours. For files larger than 5 GB, Wormhole uses peer-to-peer transfer to send files directly from your browser to the recipient, so you need to keep the page open until the recipient downloads the files.

Currently, Wormhole does not have a dedicated mobile app, but the website works well on mobile devices, including iOS and Android.

Wormhole plans to introduce a Pro plan for larger file limits and an enterprise version for organizations with high security requirements. The current version is free to use.

The source code for the streaming encryption implementation is open source. The full client and server code may be open sourced in the future.

If you believe you've found a security vulnerability in Wormhole, you can report it. Wormhole offers rewards of up to $1,000 for valid security issues and will work with you to resolve the issue promptly.
