Spock command 9 key is used to decrypt UMD leaves stored in [[IDStorage]]. Those leaves are then used in Spock command 8 to decrypt the UMD master key (per disc key). Then this key is used in Spock command 10 to decrypt the UMD raw sectors. Each different PSP region seems to have its own set of UMD keys. | Spock command 9 key is used to decrypt UMD leaves stored in [[IDStorage]].
