This allows libaacs to skip directly to step 3. Thankfully, in case no valid Processing key is available and/or the Host certificate has been revoked, libaacs has an alternative way to decrypt a disc: by providing a valid VUK in the KEYDB.cfg file. The advantage of this method is that until the Host key/certificate is revoked, and as long as the disc uses an MKB version for which the Processing key is known, libaacs is able to compute the VUK of any disc. This is usually irreversible and can only be fixed by providing a more recent Host key/certificate (for Windows users, this corresponds to updating their software player). Once revoked, a drive is not able to read both new and older discs. However, the Host key/certificates are regularly revoked through the propagation of new Blu-ray discs. If libaacs finds a valid processing key for the disc MKB version as well as a valid Host key and certificates, it can start the decryption process from step 2. non revoked by the drive) Host key/certificate
