Peertransfer

In-browser secure peer-to-peer filetransfer in three simple steps:

1. Select the file you want to send.
2. Open the generated link on other PCs.
3. Download over a direct, authenticated and end-to-end encrypted line.

Thus the file will only be available for download as long as the sender keeps his browser tab open.

Features

• Data is sent directly peer-to-peer.
• Data is transferred using end-to-end encryption (due to WebRTC).
• The messages that are relayed by a server to initiate the p2p WebRTC connections are encrypted (to protect against IP leakages and man-in-the-middle attacks while initiating WebRTC).
