61w ago - It's been awhile since the last IDPS update, and today I've created this PS3 IDPS Viewer homebrew application based on research I'm doing and had not planned to release the tool out yet, but if someone needs it here it is (Thanks to J-Martin for the logo).
When the program starts you will see the typical intro screen, if you choose "Yes" you will see the data from your PS3, if sounds three beeps indicates that it was not possible dump and show the error message, and if all went well sounds a beep and you are able to see the data.
Automatically saves the IDPS in dev_hdd0/IDPS.bin, you must open it with a hex editor and look hexadecimal values, for example (IDPS false, I will not reveal my IDPS):
00 00 00 01 00 85 00 05 87 15 A4 4D 47 64 F6 AA
The IDPS in this case would be: 00 00 00 01 00 85 00 May 87 47 64 15 A4 F6 4D AA
It has been tested on PS3 FAT, SLIM should work perfectly in also.
Finally, in related news PlayStation 3 developer naehrwert has recently blogged (nwert.wordpress.com/2011/12/24/individual-infos/) about PS3 Individual Infos, to quote:
One of the PS3′s console specific cryptography works as follows:
At factory time there is a console specific key generated, probably from a private constant value and a console specific seed. Maybe that’s the key used for encrypting bootldr and metldr. Fact is, that metldr stores another console specific keyset (key/iv) to LS offset 0x00000.
That keyset is probably calculated from the first one. At factory time the isolated root keyset (how I call it) is used to encrypt the console’s “Individual Infos”, like eEID. But not the whole eEID is encrypted the same way, special seeds are used to calculate key/iv pairs for the different sections.
And not even that is true for every eEID section, because for e.g. EID0 another step is needed to generate the final section key(set). Each of the isolated modules using such an “Individual Info” has a special section that isoldr uses to generate the derived key(set)s.
But the generation works in a way, that the section data is encrypted with aes-cbc using the isolated root keyset, so it is not possible to calculate the isolated root keyset back from the derived key(set)s, because aes shouldn’t allow a known plaintext attack.
So far I can decrypt some of EID0′s sections, EID1, EID2 and EID4. EID5 encryption should be similar to EID0′s but I lack the generation keys for that one.

I will release when everything is done and user frindly. I dono see a reason to release ACID CFW when it in first was a Retail/Debug hybried and now im working on the convertion of Retail to Debug Consoles. So i will release ACID CFW together with the convertion tool for cex2dex tool and do a reall full functional Debug CFW.
To time im testing a lot of stuff and coding the idps-tool app together with end user gui version. the Tool will be able to guid you truth the whole process and have a lot of buttons so you mostly only need to do a click and get your pck calculated, eid decrypted - patched and re- encrypted and a request_idps.txt generated.
Im working alone cause it seems the most coders of the scene are not interested in to help and others who allready also know what to do wont tell and also wont help us.
But just be a bit patient and i will do my job as good as i can and at it the end a lot of users will be surprissed what a debug ps3 in conclution with target manager and a few tricks will be possible.
At all the peace-breakers: I cannot share the bad mood in here... Even if cfwprophet doesnt give you/us your/our wished tools there is no need to front him.
At least they (cfwprophet, nabnab) take their time 2 EXPLAIN the users, why a method is not what it looks like. With their knowledge, they acctually dont need to waste their time in helping us, especially when the most of the users cannot do anything with the infos.
BUT there are some users, for whom their effort is a BIG help, so plz let them "talk"
I just cannot see it, why 1 team (our scene) cannot hold together and just wanted to bring some peace in here..
