UIF (User Interaction Flag) DO support

In OpenPGP card specification version 3.3, we have UIF DO description.
GnuPG should provide command line interface to change the value of these data objects (one for signing, one for decryption, and one for authentication).



Event Timeline

gniibe triaged this task as High priority.
gniibe created this task.

Priority is high, because Gnuk Token requires this feature for testing its implementation.

Interaction will be something like this:

$ gpg --card-edit
gpg/card> admin
Admin commands are allowed

gpg/card> uif
usage: uif N [on|off|permanent]
       1 <= N <= 3

gpg/card> uif 1 permanent
gpg/card> uif 2 permanent
gpg/card> uif 3 permanent
gpg/card> quit

I think we should not backport this to 2.2 - okay?

No. I intentionally select: Not-backporting this feature.
The feature is added for Yubikey, in the specification.
Use of the feature by Data-Object is not that so useful.
