gcauth_sm "KIRK" calls to F00D
The use of os0:sm/gcauthmgr_sm.self is to support the next generation of KIRK. It uses a similar input structure to the original KIRK on the PSP.
PSP support
4,7,0xC,0xD,0xE, 0x10, 0x11, 0x12 are the classic PSP KIRK Services supported by gcauth_sm.
New PSVita Codes
0x14-0x19, 0x1b-0x23 are the new KIRK Services supported by gcauth_sm.
0x14 is the 224bit ecdsa keypair gen. The only input is an empty buffer size (3*0x1C) it returns 3 values. Private key, Public X point, Public Y point. Each value is 0x1C bytes long.
0x16 is random 224bit generator. It will return 0x1C bytes of random data into the buffer.
0x17 -0x19 are the 224bit ecdsa versions of psp's 160bit 0x10-0x12
