Use existing gpg key?

Can't I use my existing gnupg key? Why create a new pair?

Hello @vikasrawal. Unfortunately you cannot import an existing gpg key.
I have not actually checked if this is easy to add (including error handling, checking if the key is OK etc.). I can keep this issue open to track this feature request.

Always creating a new pair in each client (chromium/firefox/android) can be considered more secure: if you ever lose a device you can simply revoke the key on your server that is specific to that device. You wouldn't have to reissue a new key to all devices that share this key.

Between clients there can also be a difference in what is supported. For example, a key generated in chromium/firefox would not work on android due to limitations in the available software and I believe the same goes if that key was generated with default parameters on your linux server.
