Usage with yubikey?

[MarcCoquand]

Hi!

I'm using the age-plugin-yubikey to store my age keys. When trying to use that together with sops, I've added

AGE-PLUGIN-YUBIKEY-XXXXXXXX

To my sops/age/keys.txt file, but when trying to edit a file I'm getting this error:

    - | failed to load age identities: failed to parse
      | '/home/me/.config/sops/age/keys.txt' age identities: error
      | at line 7: malformed secret key: unknown type
      | "AGE-PLUGIN-YUBIKEY-"

Am I missing something? Or is this maybe just unsupported? I'm running sops version sops 3.9.1.

It's working fine with passage atm.

You are using a very old version of SOPS. The current release is 3.12.1. Age plugin support was added in SOPS 3.10.0 (https://github.com/getsops/sops/blob/main/CHANGELOG.md#3100), which is likely what's needed for Yubikey support.

Ah! So obvious. I was using the version from my distro. Updating to the latest version fixed it.
