Bug 515547

Summary:	Signing with OpenPGP keys lists the keys seemingly unordered, making it next to impossible finding the correct key if one has a lot of keys.

SUMMARY

When I want to digitally sign a document, use OpenPGP keys for this, have a lot of keys (for each email address a different key and a lot of email addresses), I cannot find the key to use since the list presents the key seemingly unordered (ordering seems to be key creation date).

Which makes this functionality practically useless for me.


FEATURE WISH

Be able to sort the OpenPGP keys when using them for signing by email address and other attributes.


STEPS TO REPRODUCE

1. Have a lot of OpenPGP private keys,
2. configure Okular signing backend to use OpenPGP: "Settings" -> "Configure Backends" -> "PDF" -> "Signature Backend: GnuPG (S/MIME)" -> "Allow PGP keys for signatures (Okular extension)",
3. open a document where a digital signature can be added,
4. Do "Tools" -> "Digitally Sign ..."
5. Be presented with a long list of possible identities (OpenPGP keys with their email address) in now useful order.


OBSERVED RESULT

Be presented with a long list of possible identities (OpenPGP keys with their email address) in now useful order.


EXPECTED RESULT

Keys ordered by email address by default, other ordering options (Key ID, real name, creation date) optional.

Correcting a typo:

"now useful" should be "no useful".

How would you like them sorted?

> How would you like them sorted?

I think different people will find different sorting options usable.

For me, Email address ("ID"), but that would not really work for keys with multiple IDs.

I propose to add an option to select sorting by Fingerprint, email address ("ID"), real name, creation date, expiration date,  
as well as a search field.
