GPGMail and signing subkey

I generated a GPG key back in 2013, which got esca capabitilies. Later, I generated a signing subkey and i wanted to use it. I tested this by sending signed email to myself. When I wanted to check, which key was used for signing, I saw the ID of my primary key (and thought that subkey was not picked up). I then verified this by using gpg on command line. It showed that GPGTools used the correct subkey for signing the email.

However, it would be great if I could see subkey id directly in (e.g. after clicking on "signed" mark and getting more details). The following was already discussed here:

    Hi Adam,

    good news - we now show fingerprint, creation and expiration date of the subkey when a signature was created using a subkey. Subkey info will not be shown when no subkey was used to sign.

    We are happy to solve this long standing request.

    While we were at it, we decided to give the signature details view a major cleanup:

    • we removed the top section listing name and e-mail (those infos are displayed in the details already)
    • we prevent any need to scroll in this dialog (why not use the correct window size right away if we can)
    • details are always extended and by that there is no longer the need to even have a "Details" section
    • more focus on fingerprint of key + subkey by restructuring the order of info

    These changes apply to both the signature attachment details view as well as the signature details view.

    If you want to test the changes feel free to download the latest hotfix GPG Suite.

    All the best,

    Disclaimer: This is a development version which has not been thoroughly tested yet - bugs or crashes are to be expected. Thanks for helping us test.
