==== EID0 section 6 seed for encrypted ECDSA private key ====

* Location: aim_spu_module.self
Notes:
* This seed is the equivalent of the PSP KIRK command 0x10 AES128ECB seed (idskey0).
* Does EID0 section 0xA (or others) use the same seed ? Else why not to search their seed ;) ?


==== EID0 section 6 seed for encrypted ECDSA private key (Kirk command 0x10) ====
1) aes-256-ecb encrypt the seed with per-console EID0_key, in order to obtain the 128bit decryption key to decrypt your per-console encrypted ECDSA private key.


<pre>33793B9F79E2EBAE55D4D6BF0ED376E6</pre>
2) aes-128-ecb decrypt the encrypted ECDSA private key, located in the decrypted EID0 section 6 at offset 0x88.


Notes:
3) Verify the ECDSA private key. See KIRK command 0x10 on PSP or PS3 wiki (same public key and curve).
* This seed is the equivalent of the PSP Kirk command 0x10 AES128ECB seed (idskey0).
* EID0 sections 7-0xA use a different and unknown seed.


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.
* Location: pspemudrm (KIRK)


2) aes-128-cbc decrypt with iv=0 the encrypted ECDSA private key, located at certificate offset 0x88.
==== EID0 section 0xA seed ====


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).
