Support encryption for objects – continued with proper UI integration

[sampsapenna]

Proposed solution

The working encryption interface needs to be interfaced with the UI in a proper manner. The encrypted upload process needs to be available via the ordinary UI that an end user will use, so it will need navigation items pointing to it etc.

DoD (Definition of Done)

There exists an encrypted upload implementation in the UI, that the users can navigate to without knowing the direct address for the view.

Testing

Visual testing of the functionality, maybe feedback from the customer support eventually.
