[pinoytechno]

more info?

[elser1]

wish i wasn't so old and dumb. i'd love to be able to do this.

oh well back to psn i guess. LOL

[Weezum]

i wanna do this so bad. I've dumped everythng using memdump. played around with flow rebuilder a little got some files for from the nor now i'm jus lost with reading the bins can't find EID0 Key Seed and EID0 Section Key Seed. wish some one would walk me thru this imma be up all night trying to figure this out. don't want a program to do it for me would love to get hands on with this...

You must install Linux on your PS3 and use MetldrPWN exploit to dump your EID Root key then use this EID0 key seed and section key seed to generate a full EID key set for encryption/decryption process.

verified.. it's correct eid_root_key .. thx to you know who you are

now the other part... any hints on this part guys... thx

is aespipe used for AES encrypt? the original guide is kinda alien like, i bet they do with a blink of an eye...., any help on the command to put in terminal like:

use AES Encrypt to Encrypt EID0 Key Seed as data with EID Root Key as Key and EID Root IV as IV

aespipe -e/ aes256 eid_section_key_seed as data? bin file? -? eid_root_key-o root_iv key
something like that right

Look here. http://www.ps3news.com/forums/ps3-ha...tml#post420588

You need OpenSSL.

must have overlooked that part... thx again guys i have to take the offer though.. cheers rikukh3 in advance!

anyway, testing myself this encrypt part using openssl/cygwin

first i saved EIID_key_seed as a txt file - EID0_Key_Seed.txt with Notepad++

AB CA AD 17 71 EF AB FC 2B 92 12 76 FA C2 13 0C
37 A6 BE 3F EF 82 C7 9F 3B A5 73 3F C3 5A 69 0B
08 B3 58 F9 70 FA 16 A3 D2 FF E2 29 9E 84 1E E4
D3 DB 0E 0C 9B AE B5 1B C7 DF F1 04 67 47 2F 85

saved eid0_section_key_seed the same way - EID0IV.txt

2E D7 CE 8D 1D 55 45 45 85 BF 6A 32 81 CD 03 AF

cp this command into openssl:

openssl aes-256-cbc -e -in EID0_Key_Seed.txt -out EID0IV.txt -nosalt -K 11A534612CE5FC48614BF01CA32378804563323B22A451841CF2654B33DE98A7 -iv D43R5452282A48432F9YB46CDET852R6 -p -nopad

errors out with this:

key=11A534612CE5FC48614BF01CA32378804563323B22A451841CF2654B33DE98A7
iv =D43R5452282A48432F9YB46CDET852R6
bad decrypt
3688:error:0607F08A:digital envelope routines:EVP_EncryptFinal_ex:data not multiple of block length:evp_enc.c:228:

any pointer on the key's, should one pass them tru hex2key2bin or something to read properly?

thx!

[elser1]

so if i actually did this to my console, what exactly would be the benefits. more than say rebug?

[sguerrini97]

I will try with hexkey2bin soon, you can try to remove "space" and put the entire HEX code on one line, like this:

EID0 Key Seed

ABCAAD1771EFABFC2B921276FAC2130C37A6BE3FEF82C79F3BA5733FC35A690B08B358F970FA16A3D2FFE2299E841EE4D3DB0E0C9BAEB51BC7DFF10467472F85

Sorry for my english.

Here there are EID0 Section Key Seed and EID0 Key Seed converted with hexkey2bin if you need: http://www.mediafire.com/?ck79h4nozh0eb58

[Weezum]

can this be done with mem dump?

[haze67]

need to let the info sink a little, thx both of you for the help, i'm seeing all files are in my dexmod thx again bro! ...using these as an example to fully understand the process, and yes it's the way the keys are used in openssl to work correct, i'm doing it wrong

the hex2key2bin converted eid_key_seed/eid_section_key_seed ..those files are identical tho if you c/p those from mainpost into HxD-new file and save as bin, it's the same, i'm guessing if one do this all PS3-linux then this hex2key2bin is used?!
