Croc: Command-line secure file transfer tool

<< < (2/2)

Nod5:
A similar tool: magic wormhole
Some discussion of both here https://news.ycombinator.com/item?id=27262193
Croc had some vulnerabilities earlier this year but are fixed now.

wraith808:
Thanks for the info on Magic Wormhole. Love the fact that it has a gui and a mobile client!

Shades:
As I was in need of transferring a rather large file (about 400 GByte) from a remote location a problem was encountered. None of the computers I normally use for file transfer is able to cope with such a large file. So, I was tempted to try out croc to transfer the file directly to my workstation.

The remote computer is not a "weakling" by any stretch of imagination (16 GByte RAM, 3 year old Intel Xeon CPU, fast drive), but waiting 7+ hours now for a code to be generated by croc (to actually start the transfer) is rather long. Even when the file is about 400 GByte.

And installing Python on both the remote PC and my workstation just to make Magic WormHole work, seems less than ideal as well.

I didn't have to install Python to get Magic Wormhole to work. There's a self contained exe.

Or install Wormhole William - https://github.com/psanford/wormhole-william/releases/tag/v1.0.5

Or Wormhole Gui - https://github.com/Jacalz/wormhole-gui

It sounds like it uploads the file to the proxy before generating the code.

If both PCs are running Windows, I would still recommend an older version (1.x) of BitTorrent Sync (BT Sync) for transferring large files. It's direct peer-2-peer with no intermediary server, and does it in little parts using BitTorrent. So transfers can start almost immediately and if the connection gets interrupted partway through, it can resume without issue once the connection is re-established.
