Language Specific Code

[jschpp]

Since you are using Select-String to look for the english message parts in the gpg output the gpg check will fail on a non english os.

It's more or less understood that the output of gpg --verify shouldn't be parsed like that. See this thread: https://lists.gnupg.org/pipermail/gnupg-users/2005-July/026212.html

Instead you should use gpg --status-fd 1 --verify which will add machine readable output.

I didn't know that. Thank you!

If you'd like to submit a PR, go for it. I’ll review it and merge it when I can.
