== Encrypted Individual Data - eEID ==


eEID certainly stands for encrypted EID as each section eEID embeds is encrypted. EID certainly stands for Encrypted Individual Data. Why two 'e' in eEID ?
eEID certainly stands for encrypted EID. EID stands for Encrypted Individual Data. EID is the equivalent of IdStorage on PSP and PSVita.


EID is the equivalent of IdStorage on PSP and PSVita.
It is 0x10000 bytes in length (64 kB) but only the first 0x1DD0 bytes are used. The rest is padded with 0xFF.
 
eEID is decrypted by metldr and is passed over to the isolated loader which may pass it to a SELF. We can see this in graf_chokolo’s original payload.

It is composed of 6 sections numbered from 0 to 5.

EID0 embeds many (usually 11) AES128CBC encrypted sections. Each section is a IDPS Certificate.

====== EID0 sections 6 and 0xA crypto ======


EID0 section 6 is used in the PSP emulator by the DRM crypto engine to retrieve PSID. EID0 section 0xA is used by aim_spu_module to retrieve OpenPSID.
EID0 section 6 is used in the PSP emulator by the DRM crypto engine. It corresponds to PSP KIRK commands 0x10, 0x11 and 0x12 verification of IdStorage Certificates. See also [[http://wololo.net/talk/viewtopic.php?p=20715#p20715]] and PSP wiki for PSP crypto stuff.


These sections' certificates uses PSP certificate keyset. It corresponds to PSP KIRK commands 0x10, 0x11 and 0x12 for verification of IdStorage Certificates. See also [[http://wololo.net/talk/viewtopic.php?p=20715#p20715]] and PSP wiki for PSP crypto stuff.
Note: What's interesting is that on PS3 it uses ECDSA curve VSH type 2 with the PSP IDS Certificates public keys, whilst it uses a different curve with the PS3 exclusive Certificates (for example section 0). That's maybe how Davee and Proxima figured out the KIRK 0x10 and 0x11 ECDSA crypto keys. But not sure because their work was in 2011, not in 2012 nor 2013 (naehrwert) and it seems PS3 uses a different seed for encrypting the ECDSA private key (see section 6 ECDSA private key seed).
