input from stdin/pipe

[kradalby]

Hi!

I found myself wanting to script the rotation of a key I use with ragenix, and I have so far been unable to "trick" my editor to pick it up from from being piped/stdin and I was if anyone has considered adding a mode for updating a secret form pipe?

Usecase:

I have a script to generate a new Tailscale pre-auth-key that I want to use when setting up a new server, it outputs a limited key to stdin and I would like to do something like:

ts-preauthkey | ragenix --edit secret/tailscale-preauthkey.age

currently, I do it in a hacky way with a "fake-editor.sh":

/bin/bash
cat >"$1"
exit 0

and

ts-preauthkey | ragenix --editor fake-editor.sh --edit secret/tailscale-preauthkey.age

which works fine, but I suspect that this might be a usecase for others too.
