Simple and secure peer-to-peer file transfer

Send files securely and quickly directly from one machine to others using a small webpage and a few words.

file.tel allows you to create an ephemeral and easy to type link to transfer files securely from one machine to the other without having to upload them anywhere.

• We generate two random secrets encoded in unambiguous and easy to pronounce words
• Both sides of the transfer use Webtorrent websocket trackers to find each other based on the first secret and open a WebRTC connection
• We use the second secret and the connection to derive a strong shared key using SPAKE2
• We transfer the files encrypted with the shared key using webtorrent
