Try to find a 128-Bit key in a 4 GB memory dump, if you don't know where to start. Especially when the key is only present in RAM for a few milliseconds...

Depends if you have a pan and some liquid Nitro...

OK let me get this strait.
Are looking for d = Private key.
Or are we looking for a class that retrieves d in an unencrypted form.
Or is the main objective of this to solve for the certificates to build a class that enables us to use them against the disc in question.
I know this isn't going to be any walk in the park.
The idea of Brute force is not going to be of use. leased not for another 20 years when a standard PC can simultaneously compute 100,000 P-flops. and still have the computing space to do your taxes and encode a full HD movie.
I think that slysofts secret is that they have found a way to copy the device certificate and use it to interface with the Disc is self. (But I have not any idea theory only) The way they get away with it is that it remains a secret as to what they actually did. But this is my own conclusion of course.
The problem with using this type of method is that any device whos firmware has been tamped with will be revoked.
Of Course total noob here so
PS. here is the wiki on the encryption.
