Hallo,

has there been any action to set up a brute force key recovery scheme
for the DVD keys like it has been done for normal message encrytion?

Bye

Since the source hasn't been released, there probably isn't much
point to this yet. Why not wait a little on this and see what shakes
out :)

cheers,
aaron

Don't worry about the player keys... It won't be a problem.
The computational effort to find new ones is minimal [15 hrs for all 400 
keys on a dual processor machine, assuming you know the title key. Another 
30 hrs on the same machine if you don't].

Other interesting things:
Many of the 400 keys are the same.

Players can and do have > 1 key.

Brute forcing the player keys on a disk gives you a set of potential 
keys... But some of them won't work in general [they just happen have the 
same mapping for the particular encrypted text].
