WebWormhole from developer @_saljam creates secure ephemeral pipes between computers to send files or other data.
It is inspired by Magic Wormhole. It differs in that it uses WebRTC to make its connections. It can be used, among other things, in browsers.PAKE is used for authentication and data transfer is secured by WebRTC DTLS-SRTP (rfc5764).
Croc is a tool that allows any two computers to simply, fast and securely transfer files and folders. Also secured using PAKE.
