thanks :) Euss

About eid2 des iv

just a quick heads up. both eid2 des ivs (the zeroed one and the other one) are valid to use. in a way, both glevand (zero iv) and naehrwert (fixed iv) are correct. make sure you consult with naehrwert for more info.

zecoxao

@zecoxao Just use openssl des-cbc -d -in pblock.desenc -out pblock.dec -nosalt -K 6CCAB35405FA562C -iv 989A955EFDE7A748 -p -nopad and openssl des-cbc -d -in pblock.desenc -out pblock.dec -nosalt -K 6CCAB35405FA562C -iv 0 -p -nopad Only the second one vector is valid. Thank You.

@Zer0Tolerance

it's very rare to see naehrwert wrong. maybe the algorithm is handled differently in libeeid(polarssl) than in openssl? i'll talk to him when i have a chance ;) either way, thanks :)

@zecoxao

Im sorry, but iv must be zero. :(

@ZeroTolerance

I'm almost sure i was able to decrypt default.spp

please check all 3.15 key combinations possible.

Thanks :)

@zecoxao

Im checked it and could not decrypt metainfo into default spp, please provide me the decrypted metainfo as proof.

@ZeroTolerance

Unfortunately i don't have it anymore. but i'll try to decrypt it anyways :)

@zecoxao

Please recheck (retry) it if possible. Im sure that we needed another key(set) to decrypt default.spp for ceb.

@ZeroTolerance

yes, you're correct. just tested other combinations and none of them work.

About EID0_0_UNK1

@ZeroTolerance

Pretty sure it's z1 and z2 (2 hashes). looks like it's a metadata of sorts :)

@Zecoxao

Maybe, maybe not. hash algorithm is unknown yet.

@ZeroTolerance

Have you tried checking if it's a pub from another curve?

@Zecoxao

Pub is a point with X and Y. One Pub for one Priv. These "hashes" are not constants. So this is not a Pub. It can be two hmac-sha1 or something. IDK what is this.

Syscon pinouts and schematics

PS3 Power control and switches schematic for CECH-25xx series
Motherboards JTP-001 or JSD-001, SYSCON SW-x series, Switches board HSW-001, and 4 pins PSU connector (CN101) for PSU models APS-270 or EADP-200DB

This was made time ago based on several schematics made by mr.dutch, i joined all them together and added some corrections to the HSW-001 board circuit and a retracing for better placement and custom conectors made in kicad

It was not uploaded to wiki before because im not so sure if the same schematics is used in all the syscon SWx series, or if is dependant of the motherboard, etc...

I noticed you are looking at syscon pinouts so im uploading it now in case is handy
