It is necessary to do some investigation, and these things might help:
secure_com_lib_internal_key::FactoryInit_Password -> 2EA267093B4556ED9D3BE62E115D6D59


* unselfing every self possible and seek for hardcoded data inside the elf
secure_com_lib_internal_key::SC_BE_PayloadKey -> 6933CEE7A518E5B8CBE1FC14B261B765


* read the metadata of the self using readself(2) and encoded print_hash function
secure_com_lib_internal_key::SC_BE_PayloadKey -> A3ADB99A21E47ADFF3FD7FC3173981CA


**print_hash accepts two parameters (offset,length) where offset is where you want to localize the position and length is the lenght printed in bytes
secure_com_lib_internal_key::MAGIC -> 0xAD1A0000000000000000000000000000
 
* reverse engineering (whoever is capable of this and wants to give it a try is welcome to do so)
 
If i wasn't dumb to look for this, then certainly you, whomever you are, are not, and you're welcome to give it a shot at this :)
 
Good Luck
 
= Theory about EID1 and EID4 =
 
* EID4 shows the omac of the decrypted values in plain form when in encrypted state
 
example:
 
ENCRYPTED
<pre>
AA F3 F9 3F CB 2C 10 97 C1 24 6A C7 1B 72 79 0B
88 B1 00 0E 9B 0D 95 A3 D7 3E 3E 9C 6F 40 32 D0
04 33 3E 57 7E 1C ED 87 FA 92 56 09 28 48 34 31
</pre>
 
DECRYPTED
<pre>
02 0F 2A 40 2F 6B 0F 38 47 CB AC 2A B2 E1 5B D9
C1 BC 45 64 6D C5 E7 DB 51 3A 4C B7 FF 7B 4E F3
</pre>
 
the 3rd 16 byte value in the encrypted section is the hash in cmac-mode of the decrypted 32 bytes
 
* the same happens in EID1
 
assuming this, are we safe to say eid1 is ALREADY decrypted OR does it contain aditional crypto layers?
if it IS decrypted, what is inside it? they're exactly 640 bytes. that'd give room to 40 16 byte keys or 10 64 byte seeds.
