Add a way to view other users' device keys

[HendrikF]

This is needed to publish the own keys

[richvdh]

Your own device key is visible via the user settings panel.

I'm not clear what purpose this would serve, otherwise?

[HendrikF]

That's correct, but I cannot see the device keys of my other devices.

[richvdh]

ah, right

[albjeremias]

I can see my own keys on my settings. I think this can be closed!

#6277 also presented a use case for viewing already-verified keys from other people

[grinapo]

Also, there is manual-web-of-trust-simulator when I verify most of the people, then a new member asks me the verified data of the devices and accept them by using "legacy verification".

Fo that I have to be able to see the key material of the already verified devices.

UI-wise it would be nice to have a link on the device name which would pop up a window with the device key data, which would be copiable. (Technically it would be nice to have a full list of the verified device keys and fingerprints to be shared, but... that's probably for another day.)

This is even useful in a cross-signing world still, and would be nice to support it somehow.

I guess this could be added to this dialog https://www.figma.com/file/wwqBo5oAFfk8XKmtd2YaIs/Cross-signing?node-id=6%3A2951

I understand that this is an "advanced" feature that is not often needed, and has the potential to make the UX confusing for the large majority of users. I do think it is possible to add this info without making the UX any more complicated. For example, when I go to the sidebar and click on an unverified user, I can see a list of devices there and click on any device to start the verification:

But once a device is verified, it is no longer clickable. I find that confusing as it is.

So I propose making the verified devices clickable and when they are clicked, it would show either a tooltip or a dialog that just contains some info about the verification, e.g. the device key fingerprint, maybe something else. The word "Trusted" is even colored the same as other clickable text.
