Version NID
1.03-3.60 0x24C4CE64

Used by sceSblSpsfoMgrVerifyForDriver.

Issues kprx_auth_sm command 0x80001.

Spsfo (signed param.sfo) file is located in game cartridge at path gro0:gc/param.sfo. It can also be loaded from host0: on DevKit. It has 3 parts: CF header and certification, plain SceSpsfoHeader and plain SFO (maybe reduced).

typedef struct SceSpsfoHeader { // size is 0x200 usually
    int version;                  // ex: 1
    SceSize size;                 // header size
    uint64_t system_version;      // ex: 0x0330000000000110
    char titleid[0x20];
    uint64_t parent_authority_id; // ex: 0x2800000000000030
    uint64_t process_authority_id;
    char reserved[0x1C0];
} SceSpsfoHeader;

Note : SceSpsfoHeader and spsfo_ctx may be different
int sceSblAuthMgrVerifySpsfoForDriver(spsfo_ctx *ctx);
