SceKrm

Key ring manager module.

It works a bit like DMAC Manager and Magic Gate Key Manager (for example it uses OpenPsId and sha256). Its syscalls requires the calling app to have an appropriate SELF capability. It might be the equivalent of Magic Gate Key Manager for Play Ready. It is imported in sceplayready.suprx in some usermode applications, usually online TV streaming applications. See SceAppMgr.
