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 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.
