Well, it might be possible, that the new key will be public again.
ORF is now dark since 5 Weeks. No new keys have appeared.
Dont know exactly, why the old key was public, and, I am no specialist in this matter.
From what I read in the forums, the old key was public because of a bug in the used cards. But these Cards have not been updated, only new cards which do not have this bug.
AFAIK cryptoworks in general is not broken.
If it is correct what I read, it is unlikely that new keys will appear soon.
