SELF files are a wrapper around encrypted ELF files. The encrypted header contains keys to decrypt each encrypted ELF program, which are decrypted and loaded individually. Because of this, a copy of the ELF headers and ELF program headers are stored in plain text next to the Certified File header.
Authority Id
8 bytes long. Located at offset 0x80 in PSVita SELF header.
sceAppMgrConvertVs0UserDrivePath checks the Authority Id to limit mount points.
0x2800000000008000
(SceWebCore eboot.bin - NPXS10017 / NPXS10037 on 1.69-3.01, replaced later by SceWebKit).
0x2800000000008003
(SceWebCore) can access vs0:data/external/cert/
and vs0:data/external/webcore/
.
0x210000101CD20007
(PSM Dev Assistant can access vs0:data/external
and vs0:sys/external
