Transfer.sh – Easy file sharing from the command line
This is exactly the use case for Magic Wormhole, which is what the cool kids use to transfer files:<p><a href="https://github.com/magic-wormhole/magic-wormhole" rel="nofollow">https://github.com/magic-wormhole/magic-wormhole</a><p>Magic Wormhole uses an end-to-end PAKE to create an encrypted transport between two points in the Internet, using a rendezvous server.<p>It doesn't store files, which is almost never what you want; it's not a way to send a file and have 10 or 100 people download it. But it's probably the best way to get a file through a bunch of arbitrary network controls, NATs, &c to a desired destination. There's a Go implementation as well:<p><a href="https://github.com/psanford/wormhole-william" rel="nofollow">https://github.com/psanford/wormhole-william</a><p>... which is what I use most of the time. If you haven't played with it, I highly recommend it.
