EID Structure[edit]

EID is made of 6 "partitions" from EID0 to EID5.


EID0 embeds 11 sections.

EID0 Section[edit]

  • Size: 0xC0 bytes.
Description Length Note
Data 0x10 contains the actual data of the file (either idps or psid)
plaintext public key 0x28 contains the section's public key (without padding)
R 0x14 part of the ecdsa signature pair (r,s)
S 0x14 part of the ecdsa signature pair (r,s)
public key 0x28 ecdsa public key (can be used to verify ecdsa signature RS)
encrypted private key 0x20 encrypted blob that contains the section's private key (with padding)
cmac 0x10 hash of the previous information in CMAC mode
padding 0x8 zero byte padding for AES 128 bits encryption


  • Size: 0x2A0 bytes.
Offset Length Description
0 0x10 INIT Seed
0x10 0x80 AUTH1 Reencrypted Keyseeds
0x90 0x80 AUTH2 Reencrypted Keyseeds
0x110 0x40 Keyseeds (Time Service Purpose)
0x150 0x10 KeySeed (SNVS/Time Related)
0x160 0x120 Padding (Zeroes)
0x280 0x10 CMAC of Encrypted Data Using Master Key 0x20 if on EEPROM to CMAC (and encrypt/decrypt) or Master Key 0x10 if on FLASH
0x290 0x10 CMAC of Encrypted FLASH Data Using Perconsole Key encrypted using root key and EID1 Seeds


  • Size: 0x730 bytes.

Related to BD drive. See Hypervisor_Reverse_Engineering#Remarrying.

Description Length Note
Header 0x20
P(rimary) block 0x80 contains bd drive info
S(econdary) block 0x690 contains bd drive info


  • Size: 0x100 bytes.

Related to Communicatio. See Hypervisor_Reverse_Engineering#Communication.

Offset Description Length Note
0x00 Header 0x20 contains ckp_management_id, size of cprm keys + sha1 digest + padding and nonce
0x20 cprm player keys 0xB8
0xD8 sha1 digest 0x14 sha1 digest of previous section
0xEC padding 0x4
0xF0 omac1 digest 0x10 omac1 digest of whole eid3


  • Size: 0x30 bytes.
Description Length Note
Drive Key 1 0x10 Encrypts data sent from host to bd drive
Drive Key 2 0x10 Decrypts data sent from bd drive to host
CMAC/OMAC1 0x10 Hash of the previous bytes in CMAC/OMAC1 mode


  • Size: 0xA00 bytes.

The largest and quite possibly the most important EID of all 6. It's unknown what is inside this specific EID. We'll probably never know what's inside it without analyzing every possible clue about the PS3. And even then, it might be impossible to find its real use. Its size is similar to EID0, but it has an additional 0x1A0 bytes.
