If I remember, it's still illegal to export to "rogue states," Iran and North Korea being the major two, and terrorist organizations. But I don't think anybody has been charged for it and there's reason to suspect it wouldn't hold up given the pgp ruling.
We can't really export anything to those "rogue states" anyway. Also, as backwards as NK can act in some contexts, I dislike the classification of them as a rogue state. The kims are pretty good at geopolitics and wouldn't do anything stupid or dangerous without a good enough reason to make its actions no longer "rogue". If anything, the US is closer to a rogue state currently with its rubber stamp congress and willingness to do whatever the orangutan in charge says
