Key ring manager module.
It does almost same operations as dmac and Magic Gate Key Manager (sha256 of opensid + seed). Its syscalls requires the calling app to have a SELF capability. It might be the equivalent of Magic Gate Key Manager for Play Ready. See SceAppMgr#sceAppMgrSetSystemDataFilePlayReady.
Added this module from system version 3.00.
