=== Region locking ===
SELF or SFO?
http://www.ps3devwiki.com/index.php?title=File:Badregion-4.jpg
 
 
----
 
==NPDRM Self algorithm==
THIS DOES NOT ALLOW TO OBTAIN 3.60+ keys, nor piracy as you require the rif, act.dat and IDPS
 
On NPDRM self decryption all the security levels of the PS3 are involved: user space (vsh), kernel space(lv2), hypervisor( lv1) and isolated SPU (metldr + appldr)
 
The process start on vsh.elf...
 
===VSH===
 
Once the vsh detects that user is trying to start a self, it looks for the appinfo header type. If the type is 8, then the control digest element type 3 (NPD element) is located. From this NPD header the vsh gets the license type (free, local or network license).
 
If a free content(type 3) is detected then a generic klicense will be use for further steps (go to LV2). That klicensee is already public (see geohot npdrm_omac_key_1).
 
  npdrm_omac_key1  :  72F990788F9CFF745725F08E4C128387        # ps3publictools/include/oddkeys.h
  npdrm_omac_key2  :  6BA52976EFDA16EF3C339FB2971E256B        # ...
  npdrm_omac_key3  :  9B515FEACF75064981AA604D91A54E97        # ...
 
However if a paid content is to be loaded the vsh loads the act.dat and the rif associated to the content (if local it will locate a file with the same titleid on NPD element, if remote it will download to vsh process memory)
 
Then the signature is checked (last 0x28 bytes of both RIF and act.dat). The curves used are on vsh.self. It is a 3 element table, having the first curve nulled. The curve index for rif/act is 2. The curve values are negated as in the apploader and has the following structure
 
struct curve {
uint8_t p[0x14];
uint8_t a[0x14];
uint8_t b[0x14];
uint8_t N[0x14];
uint8_t Gx[0x14];
uint8_t Gy[0x14];
}
 
If the curve checks then vsh will process the rif:
 
struct rif {
uint8_t unk1[0x10];        //version, license type and user number
uint8_t titleid[0x30];      //Content ID
uint8 padding[0xC];        //Padding for randomness
uint32_t actDatIndex;      //Key index on act.dat between 0x00 and 0x7F
uint8 key[0x10];            //encrypted klicensee
uint64_t start_timestamp;  // timestamp of when the content was bought
uint64_t expire_timestamp;  // timestamp for expiration of content (PS+ for example)
uint8_t rs[0x28];
};
 
struct ACTDAT {
uint8_t unk1[0x10]; //Version, User number
uint8_t keyTable[0x800];    //Key Table
......
uint8_t signature[0x28];
}
 
Using the RIF_KEY it will obtain the actdatIndex:
 
AES_KEY rifKey;
uint8_t rif_key[0x10] = { 0xda, 0x7d, 0x4b, 0x5e, 0x49, 0x9a, 0x4f, 0x53, 0xb1, 0xc1, 0xa1, 0x4a, 0x74, 0x84, 0x44, 0x3b };
int result = AES_set_decrypt_key(rif_key, 0x80, &rifKey);
AES_decrypt(&rif->padding, &rif->padding, &rifKey);
 
And finally having the actDat key index the execution pass to LV2 syscall 471
 
===LV2===
 
Lv2 is accessed using syscall471 which haves the following syntax:
 
int syscall_471(uint32_t type, char* titleID, void* klicensee, uint8_t* actdat, uint8_t* rif, int32_t licenseType, uint8_t* magicVersion);
 
The function has different parameters depending if the content is debug, free or paid:
 
FREE: syscall471(npd.type, &npd.titleID, freeklicensee, NULL, NULL, npd.license, &npd);
PAID: syscall471(npd.type, &npd.titleID, NULL, &actdat.keyTable[rif.actDatIndex], &rif.key, npd.license, &npd);
 
The lv2 keeps a memory table with contentID and the associated key.
When it receives a free content (r5 is not null) then copies the titleID and the klicensee to the table. For a paid content the rif.key is converted to the klicensee using:
 
AES_KEY IDPSKey, ConstKey, ActDatKey;
uint8_t constactdat[0x10] = { 0x5e, 0x06, 0xe0, 0x4f, 0xd9, 0x4a, 0x71, 0xbf, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x01 };
uint8_t encrConst[0x10];
uint8_t decryptedActDat[0x10];
uint8_t klicensee[0x10];
int result = AES_set_encrypt_key(&IDPSVariation, 0x80, &IDPSKey);
AES_encrypt(constactdat, &encrConst, &IDPSKey);
result = AES_set_decrypt_key(&encrConst,0x80,&ConstKey);
AES_decrypt(actDat,&decryptedActDat,&ConstKey);
result = AES_set_decrypt_key(&decryptedActDat,0x80,&ActDatKey);
AES_decrypt(rif,&klicensee,&ActDatKey);
 
where CONSTACTDAT is a constant value on lv2, IDPSVaritaion appears to be IDPS (actually is the plain IDPS) (not checked but DRM_Manager_initialize (see graf_chokolo's "bible") to something with the same structure), actdat are the 0x10bytes selected by rif keyIndex, and rif is rif.key (bytes 0x50-0x5f).
 
Once transformed it is stored on memory table...
 
I haven't check further steps on vsh nor lv2 so perhaps there are further transformations on the paid case (NOT FOR THE FREE AS I HAVE DECRYPTED THOSE) so we are jumping directly to the appldr
 
===AppLdr===
 
As you can see from graf_chokolo payloads a parameter is passed on spu_args.field60. That parameter is the previously stored klicensee.
 
However this key must be transformed (again) even for the free case. The transformation is:
 
uint8_t decryptedKLicensee[0x10]
uint8_t KLicenseeDecryptKey[] = {0xf2, 0xfb, 0xca, 0x7a, 0x75, 0xb0, 0x4e, 0xdc, 0x13, 0x90, 0x63, 0x8c, 0xcd, 0xfd, 0xd1, 0xee};
AES_KEY KLicenseeKey
int result = AES_set_decrypt_key(KLicenseeDecryptKey,0x80,&KLICENSEEKEY);
AES_decrypt(klicensee,&decryptedKLicensee,&KLicenseeKey);
EY is another key located inside the apploader and klicensee is the parameter.
 
Then we can finally remove the NPDRM layer using:
 
AES_KEY key;
uint8_t iv[0x10];
memset(&iv[0],0,0x10);
int result = AES_set_decrypt_key(&KLicenseeDecryptKey,0x80,&key);
AES_cbc_encrypt(self + self->metaoffset + 0x20, self + self->metaoffset + 0x20,0x40,&key,&iv,0);
 
Observe the above code in action at [http://pastie.org/2647887]
 
Once that layer is removed we proceed as normal:
*Decrypt using AESCBC256 with the NPDRM keys to obtain the metadata keys
*Decrypt using AESCTR128 the data sha,hmac,iv keys
*Decrypt the data.

Euss they key is not duplicated... there are two cases that lead to the same (similar to the keys, two cases so two repeated tables).

Some of you asked what this algorithm is for. It has several use from backing up PSN games so they can be used with/without license (some countries allow backups, but NEVER sharing copyrighted material....) or use game updates on lower firmwares (some updates are NPDRM so they could not be decrypted and downgraded). I don't know if DUPLEX used this method or if they replaced the data with debug versions as some implied...

Also, it can be use is to modify geohot's make_self_npdrm to use non static keys for encoding. I don't know if that would be enough to make a self runnable on 3.56+ firmware. However it is a step on the right direction (I think extra modifications are required). If someone knows which parts of the self is whitelisted it would be an interesting addition to the thread. Sony was publishing 3.55 after 3.56 went online so I really interested to see which part of the SELF was whitelisted.

Others asked for the keys. I can not provide them nor functional code to avoid being sued... Graf and geohot were sued for providing the keys and/or functional code.

==== RIF key ====
SCE VERSION INFO:
However, I can provide a tip on getting the RIF key.... once decrypted bytes 0x40 to 0x4F should be xx xx xx xx xx xx xx xx xx xx xx xx 00 00 00 aa where x is random and aa is a number between 0x00 and 0x7F. It is located on the VSH.elf (remember that PPC64 has 8 byte aligment). That is a plaintext attack + dictionary(vsh). You don't need the curves as you can not sign rif nor act.dat (You can only check that file is valid). And the vsh keys can be easily find... graf chokolo called IDPS as device_id_ptr.... and the CONST is very near on code execution...

To <X>: That is a piracy related question. In addition you have published confidential info, which anyone who does RCE should avoid (I do not have the SDK). The answer is NO. Why?. See this code:

First part is an example of how a developers can easily catch that modification and stop execution making it dangerous (could get a ban!!!). You modification says that the console has access to a fake content, which only CFW will have. When patching code the modification should be done only to the case you want to fix. That modification should go on the executable not on npd libraries. That way we do not patch the first verify but we will patch the second...

The second part is the real reason why it wont work... you REQUIRE the rif for opening the edat. The rif holds the klicensee for both SELF and EDAT. In fact I assume that the klicensee follows the same transformation upto the apploader. That key that you see on the command it is only used to check the HMAC on the NPD element (see geohot make_self_npdrm omac calculations)

For executable the problem is similar as when trying to run another PPU executable the program will finish and ask the vsh to run the other process which will undergo the full decryption algorithm... again you need the rif.

But.... what will happen if we decrypt the paid edat/SELF using the rif and then resign and encrypt as a free content before executing the code??? (Assuming we can sign edat)

A MU link contains a sample act.dat and rif file for ps3 can be found if you search for "COD:BO First Strike DLC Activation  blus30591" with google.
I'm reading PSP forums, and it may possible to code an utility for cfw PS3 users, that decrypts their purchased content (A valid act.dat and rif required) if knowledge matures
I see the reason that, some users lost their bought DLC because of someting not related with piracy, for example updating fw, hdd, etc.
A PC utility could be written only if npdrm self contains a free license, etc...

=== Part 3 ===
That link was very useful. The riff structure is very similar although the signature algorithm is different.
I have some bad news. The IDPS has been confirmed as the plain IDPS with no variations (I expected it to be user ID). That means that some step is missing in the paid algorithm. For some time, people have been able to use DLC bought by other people by changing their user ID. That means that info could be extracted on any PS3, so a value coded by IDPS (which is different on EACH console) can not be part of the algorithm. I think that the value calculated by 471 is some kind of signature to validate act.dat. It will fail on different console which explains why the act.dat is deleted every time the machine boots.
So I'm going to restudy the VSH looking for the missing part. We don't know the meaning of byte 0x810 to 0x1010 of act.dat. Previously I discarded that the act.dat contained an entry for each content as it has a fixed size but it is the only place to store keys. It is a slow process so please be patient.
Meanwhile we can improved make_self_npdrm and decrypt updates (for disc games).
By the way more info on keys:

I'm not sure about that... It sounds weird. People had the opportunity to use DLC from others with account sharing. I log psn with your account and the psn generates a new act and rif for me (based on my IDPS??)
So maybe your work isn't incomplete.
 
And also, if syscall471 is used to verify act.dat, what's the purpose to call that also for free content?

Don't doubt yourself, JuanNadie! The algorithm you posted is correct. It is indeed the plain IDPS. Using your posted algorithm I was able to completely remove the NPDRM layer on an encrypted, paid SELF to get the decrypted metadata keys. I suspect the game sharing people download games while logged in to a friend's PS3. When they download the game to their friend's PS3, the NPDRM layer is added using their friend's IDPS.

=== Part 4 ===
Did it really work? Wowww... I never tested that last step as i don't have an act.dat for my current PS3 (the other has YLOD). I released the info so somenone else could test it. I modified the first message to credit you for testing
 
Then we have the NDPDRM algorithm solved and a new mystery (why changing userID at xregistry.sys allows using other's act.dat and rif).
 
If someone has access to two consoles with act.dat he should check if values from 0x10 to 0x810 decrypts to the same. If the decrypted tables are equal them we can improve the algorithm to avoid using the IDPS, so anyone that lost their act.dat but have their rif could recover their games.  
 
IDPS for 3.55 kmeaws is located at 0x80000000003C2EF0. You will also need a program for getting it (two LV2 peeks).


AppLoader keys are at 0x32510 (program memory address for 3.56 appLdr not file offset).There are 16 keys. Then there is another unknown key and then NPDRM keys at 0x32B70. Again 16 entries (some of them nulled). Then a copy of NPDRM keys at 0x33170. The revision value on self header is use as index for these table (the fail0verflow code tested all the values until it found zero padding). scekrit could be modified to get the private keys

  Add the files in the npdrm_keystuff folder to your ps3 keys folder. Create a
  file with your console's 16 byte IDPS in the 'idps' file in your ps3 keys
  folder (e.g. ~/.ps3/idps).
Copy your PS3's exdata folder containing your act.dat and rif files to your
ps3 keys dir (e.g. ~/.ps3/exdata/act.dat). Compile and have fun with your
LEGALLY purchased NPDRM games!
   
Also works on free games without exdata/idps.
 
Apologies for any existing bugs in unself. Adding these changes to
unself2 is left as an exercise for the reader.
 
  v2 info:
  Added npdrm magic to unself2 and readself2
  unself2 doesn't like the metadata section with type 3 in my game.
This section looks to be some kind of linking information. Here is a snippet:
crt0:p190002crt1:p190002libaudio_stub:p190002libaudio_stub:p190002
 
I haven't yet looked around to see if this is type of section is documented anywhere.

*fail0verflow for the orginal tools
*JuanNadie for figuring out NPDRM
*euss for his endless hours of work on the wiki

I have checked several game updates and Sony removes some of the section info (I have seen the section header removed). That data is not needed on loading game (just program header, elf header and of course the program data). The ¿lv2? creates a memory image from only the data at segment Information. It never knows the contents of the metadata section headers.

For backing up a game I think is not necessary to decrypt the data just the Self header and then modify the license type to 3 (free) reencode the NPD element resign the header with the priv and reencrypt the Self header.

I have fixed some bugs on fl0w tools and added all NPDRM stuff as well as @mallory did.
 
What's different then?
 
* unself (unself2 should not skip type 3 setction IMHO) is able to save the key/iv used to encrypt the NPDRM and patch the eboot.elf for 3.41 consoles.
*make_self_npdrm2 is able to encrypt elfs with the key/iv extracted by unself and, theoretically being accepted by OFW>3.55
 
With those tools, I've been able to "downgrade" LBP2 updates 1-4 and install them on a CFW 3.41.

===EDAT Stuff===
My WIP on decryting EDATs. I've found 4 likely keys used in EDAT processing inside appldr (included in unedat.c).
[http://pastie.org/2765146 Mostly non-working unedat]
 
====JuanNadie====
Actually an EDAT has several keys. One is in the SELF, others are at the rif and others on firmware. That an EDAT works on lower firmware only proves that the firmware has those keys.
 
BTW I have tricked the PS3 into decrypt an EDAT (Buzz). The procedure involves knowing how the NPD element is used (most of this is already published).

I haven´t fully reversed the EDAT algorithm (I’m missing bytes from 0xB0 to 0xFF) but there is enough info for a post. The explanation is for those with flag (offset 0x80-0x83) equals to 0xC which is a normal EDAT. For others values minor changes should be made. Let’s begin.
 
'''USER SPACE:'''
(Probably incomplete (enough for decryption), most of it is guessed)
On previous post I mentioned the command useds by developers to open/read an EDAT. That command has 3 parts:
 
*Verify: This parts verifies the NPD element by checking that user is authorized to open the file (using the devklic). In addition it calls LV2 to create an entry in the memory (probably using syscall471) so for further steps it will use the devklic (free) or the decrypted rif key (paid) (see SELF algorithm). I’ll call this rifkey on the rest of the document.
*Open the file: This will call kernel space. Performs several checks and creates an entry on another table.
*Read: It also calls LV2, which will decrypt and send data back.
 
'''<KERNEL SPACE:'''
 
*When an open request is received:
**Read the first 0x100 bytes of the file.
**Validates first 0xA0 bytes on EDAT. This uses appldr with the following execution (see below):
***Single execution
***Encrypted arguments
***CMAC. Key: rifkey, expectedHash: data at 0xA0-0xAF
***No Encryption erk:null,riv:null
**Validates metadatasections. Again uses appldr:
***Multi execution. Blocks upto 0xFC00.
***Encrypted arguments
***CMAC. Key: rifkey, expectedHash:data at 0x90-0x9F
***No Encryption: erk:null, riv:null
 
Once the NPD is validated (We have validated header upto 0xAF and the metadatasections( which validate the data itself)) an entry on a memory table is created, the entry created by syscall471 is erased and returns. I’ll call this the EDATEncryptionDataTable. This table has 10 entries (remember the limitation of simultaneous files opened??...). Each entry has the following structure:
<pre>
typedef struct {
    uint64_t fileDescriptor;
    uint64_t offset;
    uint64_t fileLen;
    uint32_t flag;
    uint32_t blockSize;
    uint32_tnumBlocks;
    uint8_t blockBase[0x0C];
    uint8_t devklic[0x10];
    uint8_t digest[0x10];
}EDATEncryptionData ;
</pre>
*fileDescriptor: The file descriptor
*offset: An additional offset to calculate the position of the metadataSection. Origin unknown. Values seen 0
*File len: Length of the uncompressed data. Copied from EDAT offset 0x88-0x8F
*flag: Flags required to process the data. Copied from EDAT offset 0x80-0x83. Some flags are:
**0x80000000: Debug
**0x01000000: SDAT… for those rifkey is calculated differently. Algorithm is not tested yet.
**0x00000004: Arguments for appldr are encrypted
**0x00000001: Data compressed. MetadataSection length will be 0x20 bytes.
*blockSize: The data is stored on blocks of that length. Required for decryption. Copied from EDAT offset 0x84-0x87
*numBlocks: Number of blocks on file. Calculated using: numBlocks = (fileLen + blockSize - 1)/blockSize
*blockBase: Common part of the key used on decryption. First 0xC bytes of headerHash. Copied from EDAT offset 0x60-0x6B.
*devklic: Our rif key. Copied from the entry created by syscall471. FOR SDAT it is calculated using other algorithm.
*padding: the digest from NPD. Will be the IV. Copied from EDAT offset 0x40-0x4F.
*When an read request is received:
**The system determines the blocks required (E.g; read from 0x3FFF to 0x8001 will read blocks 0,1 and 2).
**For each of the blocks:
***Calculate the blockKey as blockBase concat blockNumber.
***Calculate block offset: Start of NPD + offset + 0x100 + metadataSectionLen* numBlocks + blockSize*blockNumber. metadataSectionLen is 0x10 for flag 0xC (if compressed or with special hash would be 0x20).
***Calculate erk: AESECB128Encrypt, key:rifKey, data:blockKey
***Calculate hashKey: For 0xC is erk. (Others have an additional encryption)
***Execute appLdr with the following parameters:
****Single execution
****Encrypted arguments
****CMAC. Key: hashKey, expectedHash: metadataSection[blockIndex].hash
****EncryptionCBC erk:erk, riv:npd.digest
 
'''APPLDR:'''
 
As you know the appldr is used for decrypting SELFs (that part is documented on the wiki). However there is a second mode that is used for EDAT. To use that mode spu_arg.field35 is 5. For values 0 to 4 it will process a SELF and for others will return error. Graf_chokolo described the structure of spu_args for the SELF. However this changes for EDATs…
 
<pre>typedef struct
{
uint64_t unk1;
uint32_t hashFlags;
uint32_t encryptionFlags;     
uint64_t unk2;
uint64_t len;
uint64_t unk3;
uint64_t stateAddress;     
uint32_t field30;
uint8_t  field34;      //Must be 0,1,2
uint8_t  field35;      //Must be 0,1,2,3
uint16_t  field36;      //Must be 0,1,2,3,4,5
uint64_t field38;
uint8_t hashKey[0x10];
uint8_t riv[0x10];
uint8_t erk[0x10];
}spu_args;
</pre>
 
Above I indicated several parameters for the appldr. Those parameters are controlled by hashFlag and encryptionFlag.
 
*HashFlag: The hash is performed on input data not decrypted data. So if hash fails nothing is decrypted
 
<pre>MSB indicates how to use parameter hashKey.
 
        0x10000000: Indicates that hashKey is encrypted. Decrypt it with EDATKEY and RIVKEY
        0x20000000: Ignore hashKEY. USE EDATDEFAULTHASHKEY
        0x00000000: hashKey is not encrypted. Use it directly
</pre>
<pre>LSB indicates the type of hash.
 
        0x00000001: HMACWithSHA1. Hash Len 0x14 bytes
        0x00000002: CMAC128. Hash len 0x10 (obvious)
        0x00000004: HMACWithSHA1. Hash Len 0x10 bytes (Hash is trunked)
</pre>
 
*EncryptionFlag:
 
<pre>MSB indicates how to use parameters riv and erk
 
        0x10000000: Indicated that erk is encrypted. Decrypt it with EDATKEY and RIVKEY. riv is copied
        0x20000000: Ignore riv and erk. Use EDATKEY and RIVKEY
        0x00000000: Use erk and riv directly
</pre>
 
<pre>LSB indicates which encoding is used.


        0x00000001: No encryption (algorithm is memcpy)
        0x00000002: AESCBC128Decrypt is used.
</pre>


When a key must be decrypted the algorithm is AESCBC128Decrypt.
== Sign executables for 3.73+ (mathieulh's "drama") ==
 
Keys SHA1:<pre>EDATKEY: 84E9FC3574EAA11A9462FFA53D5EA46B4D0003BF. Already in wiki
RIVKEY: E129F27C5103BC5CC44BCDF0A15E160D445066FF. This is top secret ;D
EDATDEFAULTHASHKEY: 8A721A06ABC7BB9BF398C5EF5D6F1FD997BC0A56</pre>
 
The multiple execution /single execution refers to the ability of appLdr to store an encrypted (and hashed) data on main memory to resume the hashing/decryption operations on next execution. That data is stored at stateAddress. Basically the functioning has several submodes. One for initialization (that decrypts erk, riv and hkey) and copies the state to main memory, another for processing data, which retrieves the state, process the data and updates the state, and finally another that receives the expected hash and validates. Another submode does all these ops on a single execution (calls the three submodes).
 
Summing up (for 0xC) for each block:
*Calculate data offset: 0x100 + offset(0) + metadataSectionLen*numberOfBlocks + currentBlockNumber*blockSize
*Generate block key: concat first 0xC byte of headerHash with current block number
*Encrypt block key with rifKey using AESECB128Encrypt. This would be erk and hkey
*Calculate riv. It is NPD digest field
*Decrypt erk using AESCBC128Decrypt with EDATKEY and RIVKEY -> call result decryptionKey.
*Using AESCBC128Decrypt decrypt data from offset to offset + blockSize( if last block calculate remaining bytes rounded up to 0x10 multiple). Key is decryptionKey iv is riv
*Copy data to output file

After searching for those missing bytes I did not found any reference on code. So I zeroed them and feed the file to the PS3... The file was properly loaded and decrypted so:
-Those bits are a random padding or
-They are not checked ,nor required for creating an EDAT.
 
That means that you are able to "free" your EDATs using the method above.
Remember that you're going to need the devklic and the rifkey
 
@Octopus For p3T you don't require the devklic cause for paid decryption you only need the key from rif... so decrypt it and use it directly like any other theme
 
@EXE.trim.ALL You're right on version. LV2 uses that value to check which flags are valid. However unk4 (and unk3) which are at 0x70 are zeroes. Your info is for the next 16 bytes located at 0x80. Also you separate finalize and type. From the assembly I can say that the original source code considers it a signed integer (int32_t) (that or they have a really weird compiler cause it always load that field as a word (PPC can read a single byte)).
 
BTW the text on flowers says something about "werewolves" and the devklic
is written as an ASCII text (not binary). It was the first non free content that I decrypted on PC.
 
<!--// snip //-->
It's a pity that I would never enter on efnet (nor other sites) as long as they don't allow proxy and TOR.
:notes:
:: actually wiki accepts proxy (and tor?)
:: in case you need tor for ef.net, irc.paraphysics.net accepts tor connections
 
Finally a bit of drama: Hotz8611, I reversed your reactPSN to see the your method and discovered that you just used the info on this post. I haven't check the vsh.self mode but I suppose that youre nullifyng the curve check and generate RAP by encrypting the rifkey (An AES and another crypto algorithm of 5 rounds with shuffle, acummulation and xoring.). I thank you for making people provide me all those RAP than I'm able to transform to rifkey but next time give proper credits (I don't know if your works is based on mallory or mine but obviously is based on info in this topic).

Sign executables for 3.73+ (mathieulh's "drama")[edit source]

[21:00:58]	<Mathieulh>	selfs are a mess to generate properly because a lot of values need to be calculated from the original elf file
[21:01:11]	<Mathieulh>	the problem is right now all the public tools use hardcoded values
[21:01:19]	<Mathieulh>	that are grabbed from various self files
[21:01:21]	<Mathieulh>	but are not calculated
[21:01:34]	<Mathieulh>	well that's one of the many problems actually
[21:01:35]	<jevin> 	Mathieulh, things other than elf offsets?
[21:01:40]	<Mathieulh>	yah
[21:02:03]	<Mathieulh>	sony also did some fancy things with the compression self format
[21:02:12]	<Mathieulh>	where values are off by a certain offset etc etc
[21:02:38]	<Mathieulh>	if you want to make a proper self tool
[21:02:44]	<Mathieulh>	you first need to reverse make_fself
[21:03:06]	<jevin> 	not too hard with hexrays *cough*
[21:03:09]	<Mathieulh>	that's the initial step
[21:03:15]	<Mathieulh>	yeah it's not that hard
[21:03:29]	<Mathieulh>	then you'll figure what a big fuck up the self format really is xD
[21:05:14]	<Mathieulh>	but yeah just my self.cpp is 5 times larger than the entire source for geohot make_self/make_self_npdrm
[21:05:27]	<Mathieulh>	in terms of lines of code
[21:05:48]	<Mathieulh>	so his is missing shitloads of stuffs and only relies on hardcoded values
[21:06:06]	<jevin>	        entire headers copypasta'ed from existing selfs
[21:06:11]	<Mathieulh>	pretty much yah xD
[21:06:23]	<Mathieulh>	the ones on the tool I use are generated
[21:06:32]	<Mathieulh>	as in calculated and generated
[21:06:36]	<Mathieulh>	from the original elf
[21:06:52]	<Mathieulh>	btw unself is buggy too
[21:06:54]	<Mathieulh>	just so you know
[21:07:16]	<jevin>	        why havent you labeled the control flags? :)
[21:08:16]	<Mathieulh>	jevin I didn't feel the need to, I already know what they do anyway
[21:08:37]	<Mathieulh>	for example 0x40 is root rights, 0x20 is debugger rights and so on
[21:09:07]	<jevin>	        im guessing the self capabilities flags are offset 0x20 in the self header
[21:09:18]	<Mathieulh>	capabilities aren't in the header
[21:09:23]	<Mathieulh>	they are part of the metadata
[21:09:28]	<Mathieulh>	as in, they are encrypted and signed
[21:10:16]	<jevin>	        offset 0x10 in the section header?
[21:10:29]	<Mathieulh>	it's after the metadata keys
[21:10:33]	<jevin>	        no, they wouldnt be per section
[21:10:50]	<Mathieulh>	as in, right after them
[21:11:09]	<jevin>	        i see. so unself doesnt have enough fields in the metadata header
[21:11:35]	<jevin>	        i really should color in the hex values that are mapped to structures in unself vs ones that arent
[21:11:42]	<jevin>	        seems like it is missing a lot
[21:11:49]	<Mathieulh>	everything public is missing tons
[21:12:15]	<Mathieulh>	capabilities are optional mind you
[21:12:35]	<jevin>	        are they restrictive or permissive?
[21:13:11]	<Mathieulh>	restrictive
[21:13:16]	<Mathieulh>	(for most)
[21:42:15]	<jevin>	        Mathieulh, you said that the geohot npdrm keypair is blacklisted in 3.56
[21:42:30]	<jevin>	        i couldnt find the decrypted or encrypted metadata keypair in 3.56 files
[21:42:47]	<jevin>	        where does the blacklisting occur? is it a hash that is blacklisted?
[21:43:08]	<jevin> 	its interesting to me because we can make our own keypairs now with juan nadie's work
[21:48:45]	<Mathieulh>	<jevin> Mathieulh, you said that the geohot npdrm keypair is blacklisted in 3.56 <== not only that
[21:49:03]	<Mathieulh>	geohot stuff doesn't generate some of the npdrm specific values
[21:49:08]	<Mathieulh>	those were not checked in 3.55
[21:49:13]	<Mathieulh>	but they are checked in 3.56 now
[21:49:55]	<jevin>	        Mathieulh, gotcha
[21:50:09]	<jevin>	        is his keypair actually blacklisted somewhere though?
[21:50:10]	<Mathieulh>	there is no whitelist for npdrm
[21:50:22]	<Mathieulh>	so it's actually possible to generate valid npdrm self for 3.56+
[21:50:42]	<jevin>	        is it a check in appldr?
[21:50:43]	<Mathieulh>	that tool I made a screenshot of actually does that
[21:51:02]	<Mathieulh>	jevin yeah, it's enforced by lv1 though
[21:51:16]	<jevin>	        a hash comparison?
[21:51:27]	<Mathieulh>	yeah it's a hash
[21:51:30]	<Mathieulh>	but I won't say more
[21:51:35]	<jevin>	        ok :)
[21:51:55]	<Mathieulh>	everything you need is in the 3.56 fw :P
[21:52:16]	<jevin>	        rgr, i will poke around later
[21:52:34]	<jevin>	        the checks are unmodified in 3.60+?
[21:52:43]	<jevin>	        + new keys of course
[21:52:51]	<Mathieulh>	same checks
[21:54:53]	<Mathieulh>	jevin you won't get around crafting valid 3.56+ npdrm selfs without a proper makeself tool though
[21:57:18]	<jevin>	        would SCE make npdrm selfs work if actually signed?
[21:57:25]	<jevin>	        + crypted
