@Shanoa Happy birthday!

An improved, I think, version:

Destination:
$ nc -l -p 10002 | pv | gpg -d --no-symkey-cache | tar -x

Source:
$ tar -cv [folder] | gpg -c | nc [dest's hostname] 10002

The `tar` `-v` flag is moved to the source host, so that you can see `gpg -d`'s output better to check that it isn't decrypting bogus publickey-encrypted data.

This uses the `pv` command too, which is optional in the pipeline and is usually not installed. It behaves similar to `cat` but with a handy progress indicator.

@lack

@lack That's pretty slick, and just one command on the source host, no need to manually enter the command on the destination host. This does ofc require ssh to be set up on the hosts though.

I didn't think about it, but since my command uses `gpg -d`, a malicious actor *could* send something publickey-encrypted, yeah... one would need to check its output (which currently could get drowned in tar's verbose mode output). Also, adding --no-symkey-cache to gpg -d might be a good idea in this case.

@cyberghost@fosstodon.org Probably 🧠

Lol yeah I think virtually no one would do that

Just found out a really neat, convenient way to transfer folders encrypted and peer-to-peer on Unix/Linux.

Destination:
$ nc -l -p 10002 | gpg -d | tar -xv

Source:
$ tar -c [folder] | gpg -c | nc [dest's hostname] 10002

I was aware of something like this before, but hadn't polished it off.

@cyberghost@fosstodon.org Where did you find this atrocity

@dos I want one of these devices :')

@kyle That's really neat.

Ah good morning @indie1337@vivaldi.net!

@hackaday That's really cool @kyle!

@carlrichell Maybe a silly question, but are you planning on experimenting with getting them slim enough to fit in a laptop?
