Pretty obvious. RENC is an allowed usage for an RSA key and thus set in the mask. I restricted this but allowed to set it anyway when using the "=sr" shortcut (here to set as signing and R-enc). Thanks for reporting.

I'm wondering whether it wouldn't be better to rename (or copy) the icon to pinentry.png. It's weird if a program installs an icon with a generic name in a generic location.

I think the DocAction idea doesn't really work well because it leads to empty submenus and bogus actions in the toolbar configuration and the keyboard shortcut configuration in builds that don't include the PDFs. And now, it seems, checking whether a file exists isn't enough anymore.

I assume the support answers helped, therefore closing this.
In case there is evidence of a bug please give more information and reopen the ticket.

Sorry, I did not know (or had forgotten, I did search the tracker first).
What is the rationale for not signing the uninstallers?

This is long known and we won't fix this for gpg4win.

With Gpg4win-4.3.1 I consider this solved:

Note that the keys do not have origin information before they have been imported. My idea was to keep track of which job generated the results and somehow add this as origin information to the key list model.

I just want to remind you that we have added the possibility to explicitly disable opening of any URLs in Kleopatra. Don't introduce a new way to open a URL which cannot be disabled via the same setting.

Okay. 2342304000 in the colon output is 2044-03-23T00:00:00+00:00.
