= Information about these seeds =


The seeds presented on this page were acquired through different means. It started with a simple search (which I have to thank glevand and naehrwert for, as had it not been for those guys, I wouldn't have found myself the confidence to post this) and it went through several people who helped me along the way, and who probably wish to stay anonymous.

Without further ado, here are the seeds (both known and unknown) for several functions of the ps3.

* Location: aim_spu_module.self
Encrypt it with perconsole eid0_key to obtain the decryption key to decrypt Your perconsole ecdsa private key, located into the decrypted eid0 section 6 at offset 0x88.<BR>
Encryption algo: aes-256-ecb.<BR>
Decryption algo: aes-128-cbc. iv = 0.

Taken from: pspemudrm (kirk)


<pre>33793B9F79E2EBAE55D4D6BF0ED376E6</pre>
==== eid0 keyseed 0xA ====


Notes:
<pre>
* This seed is the equivalent of the PSP Kirk command 0x10 AES128ECB seed (idskey0).
30B0395DC5835AAA3A7986B44AFAE684
* EID0 sections 7-0xA use a different and unknown seed.
</pre>


1) aes-256-ecb encrypt the seed with per-console EID0_key (indiv+0x20) and EID0_iv (indiv+0x10), in order to obtain the 128bit decryption key to decrypt per-console encrypted ECDSA private key.
Taken from: aim_spu_module.self


2) aes-128-cbc decrypt with iv=0 the encrypted ECDSA private key, located at certificate offset 0x88.
=== eid1 ===


3) Verify the ECDSA private key by using the ECDSA public key at certificate offset 0x10. See KIRK command 0x10 on PSP or PS3 wiki (same constant public key and curve).
Used for individual SYSCON information.

== EID5 (0xA00) ==


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 it's real use. It's size is similar to EID0, but it has an aditional 0x1A0 bytes.
