This is the newest version. And the issue with FindVUK has been solved by its author nalor.

I think 1.0.2.1 is the newest version and the Mediafire link is still accessible:

Yup 1.0.21 is the latest. The MF link should still be working fine. I haven't changed anything.

Apologies if this has been answered before or it's supposed to be obvious, but how does the process of generating a key from a dump file actually work? If all that's needed to create a key from a dump file was included on the disc on hand, it would be possible to do this on the same machine, which it clearly isn't. I'd like to know where the file actually goes and what the key generation looks like from a practical and, possibly, mathematical perspective.

You can start with basic AACS information, which includes the specifications, and which should tell you about AACS 1.0. AACS 2.0 is "like" AACS 1.0, but with some upgrades.

There are obviously some missing pieces in all of these, i.e. a set of secret keys which makes the algorithms work. There are also some publicly available keys for AACS 1.0, which AACS-LA actively revokes whenever it can. But there is nothing publicly available for AACS 2.0, and this is almost certainly because such things are much harder to come by than for AACS 1.0.
