Open MKB File
An MKB file, or Media Key Block, is a unique file extension used primarily in the DVD and Blu-Ray disc encryption process. This article will, in detail, explain how you can open and use files with this extension, discussing its different formats and their functionality. As this is a slightly technical topic, it's important to note that different applications use MKB files for different purposes.
Understanding MKB Files
MKB files contain encryption keys for AACS (Advanced Access Content System) which is used by Blu-Ray and HD DVD. These keys are used to prevent unlawful copying and playback of video content. The AACS keys are stored in the CONTENTS directory on Blu-Ray discs, under the MKB_RO.inf file. For more detailed information on AACS, visit the AACS official website.
MKB Files in Blu-Ray Technology
In Blu-Ray technology, MKB files act as revocation files. These files store the host keys that have been revoked, essentially a list of non-compliant players. These players will no longer be able to play new discs without an update to deal with the versioning or revocation data in the MKB file. A detailed discussion on Blu-Ray technology is available for deeper understanding.
