Why are you encrypting a file that you're passing over SSH? This should just be `scp -C`.

croc's biggest failure is that it doesn't really do NAT hole punching, so you're limited to the speed of the relay.

A ton of the web-based WebTorrent/WebRTC based file transfer programs are extremely likely to fail on even moderately large files, >500MB.

In practical use, mega.nz and bittorrent are the most reliable ways I've found to exchange files with other people, depending on the size of the data and sophistication of my counterparty.
