Kleopatra: Check that KeyCache::findBestByMailBox is in sync with GnuPG and maybe move it
Closed, ResolvedPublic

Description

Last week there were changes / fixes to GnuPG's get_best_pubkey_by_name (not sure if that is the exact function name). This is the code gnupg uses when you do a

gpg -er aheinecke@gnupg.org

to find the best key to encrypt to.

Or which key gpg --locate-key aheinecke@gnupg.org would return.

They are defined by checking for a single mailbox.
We have mirrored code in libkleo with KeyCache::findBestByMailBox . Which was a crutch at the time as I didn't know where to better place it. I would rather have some key comparison in GpgME++ and then use it to basically only sort in Libkleo's keycache. But I didn't know how to then also add group support so I did it in the Keycache.

I'm using the function in the newkeyresolver in libkleo and by extension in GpgOL.

This deserves at least a look to check what has been changed in GnuPG.
