On a device, aeskeydb.bin becomes accessible to the root user. This has led to several community-driven tools:
Advanced tools like GodMode9 allow you to "mount" the aeskeydb.bin file as a virtual drive, letting you view or extract the individual keys contained within. Legal and Safety Note aeskeydb.bin
