Once the [[VSH|vsh]] detects that user is trying to start a [[SELF File Format and Decryption|SELF]], it looks for the [[SELF_File_Format_and_Decryption#App_Info|appinfo header type]]. If the [[SELF_Types|type is 8]], then the [[SELF_File_Format_and_Decryption#Control_Information|control digest element type 3]] (NPD element) is located. From this NPD header the vsh gets the [[License Types]] (network license, local or free). | |||
*'''Network License''' (type 01): if a remote paid content is to be loaded, the vsh loads the act.dat and the rif associated to the content (will download to vsh process memory) | |||
*'''Local''' (type 02): it will locate a file with the same titleid on NPD element (CONTENT_ID), then the signature is checked (last 0x28 bytes of both RIF and act.dat). | |||
*'''Free''' (type 03): if a free content (03) is detected then a generic klicense will be use for further steps (go to LV2). | |||
Using the RIF_KEY it will obtain the actdatIndex, and finally having the actDat key index the execution pass to LV2 syscall 471. | |||
