==== Appinfo offset 0x08 ====
for some reason named [[SELF_File_Format_and_Decryption#App_Info|vendor_id]] there.
In geo makeself it was used as: <code>set_u32(&(output_self_info_header.i_magic), 0x01000002);</code>
Not directly related to [[Authentication IDs]], but seems to have many simularities with it, seems also related to [[Hypervisor_Reverse_Engineering#Active_System_Managers_in_HV_dump_3.15|SM ; LPAR's]] and their order suggests hierarchy/permission from high (can do everything) to low (lesser abilities).

=== Encrypted phdr offset entry ===
There is one of these entries for each phdr entry in the elf file so that the ps3 knows where to decrypt the data from. (because it might also be compressed.)

=== Meta Checksums ===
There are 3 checksums at the offset specified by meta_offset.
*The first is the sha1 checksum of the entire self file.
*The 2nd checksum is the inverse of the first checksum.
*The 3rd checksum is the first checksum XORed with 0xAAAAAA..AAAAAB
The PSJailbreak payload ignores the actual checksums, but checks that the 3rd checksum is the 2nd checksum XORed with 0xAAAAAA..AAAAAB
