Thanks for pid checker Daz

 

In C++:

Code:

// Note that TCHAR map should be set to "wchar_t" or you can change all "WCHAR" instances in code to "wchar_t"

typedef HRESULT (__stdcall *PidGenXFn)
(
WCHAR* szProductKey, // Product Key to decode
WCHAR* szPKeyConfigPath, // Path to "pkeyconfig.xrm-ms"
WCHAR* szPID, // Microsoft Product ID Family (use "55041")
void* pUnknown1, // Unknown (use NULL)
WCHAR* szProductId, // Calculated Product ID ("55041-XXX-XXXXXXX-XXXXX")
struct DigitalProductId* pDigPid, // Calculated DigitalProductId structure
struct DigitalProductId4* pDigPid4 // Calculated DigitalProductId4 structure
);

struct DigitalProductId {
unsigned int uiSize;
BYTE bUnknown1[4];
char szProductId[28];
char szEditionId[16];
BYTE bUnknown2[112];
};

struct DigitalProductId4 {
unsigned int uiSize;
BYTE bUnknown1[4];
WCHAR szAdvancedPid[64];
WCHAR szActivationId[72];
WCHAR szEditionType[256];
BYTE bUnknown2[96];
WCHAR szEditionId[64];
WCHAR szKeyType[64];
WCHAR szEULA[64];
};
WCHAR* g_szPKeyConfigPath;
PidGenXFn g_pPidGenX;

HRESULT __fastcall DecodeKey(String szKey)
{
Memo1->Lines->Append("Product Key: " + szKey);
WCHAR *pkeyconfig;
WCHAR *lib;
pkeyconfig = L"pkeyconfig.xrm-ms";
lib = L"pidgenx.dll";
// start load
HMODULE hPidGenX = LoadLibrary(lib);
if(hPidGenX == NULL)
{
Memo1->Lines->Append("Error: Could not load library - file not found?");
return -1;
}
// assuming load succeeded, get the Memo1->Lines->Appendction pointer
g_pPidGenX = (PidGenXFn)GetProcAddress(hPidGenX, "PidGenX");
if(g_pPidGenX == NULL)
{
Memo1->Lines->Append("Error: Could not load library - wrong file?");
return -1;
}
bool bLastWasComment = false;
// end load

WCHAR szProductId[24];
szProductId[0] = L'\0';
// not really used, as everything is in DigitalProductId4,
DigitalProductId sDPid;
sDPid.uiSize = sizeof(DigitalProductId);
// nearly all the information (apart from Product Id) gets put in this structure
DigitalProductId4 sDPid4;
sDPid4.uiSize = sizeof(DigitalProductId4);
// and finally...
HRESULT hResult = g_pPidGenX(
szKey.w_str(), // wchar_t of String with key
pkeyconfig,  // pkeyconfig file path
L"XXXXX", // You can put anything here, but in most PID checkers it's "XXXXX"
NULL, // Unknown (?)
szProductId,
&sDPid,
&sDPid4
);
// now interpret the results...
String szValid;
switch(hResult)
{
case PGX_OK: szValid = "Valid"; break;
case PGX_INVALIDKEY: szValid = "Invalid"; break;
case PGX_MALFORMEDKEY: szValid = "Malformed"; break;
default: szValid = "ERROR"; break;
}
Memo1->Lines->Append("Validity: " + szValid); //

if(hResult == PGX_OK)
{
Memo1->Lines->Append("Product ID: " + (String)szProductId); // ^^
Memo1->Lines->Append("AdvID: " + (String)sDPid4.szAdvancedPid);
Memo1->Lines->Append("Activation ID: " + (String)sDPid4.szActivationId);
Memo1->Lines->Append("Edition Type: " + (String)sDPid4.szEditionType);
Memo1->Lines->Append("Edition ID: " + (String)sDPid4.szEditionId);
Memo1->Lines->Append("Key Type: " + (String)sDPid4.szKeyType);
Memo1->Lines->Append("EULA: " + (String)sDPid4.szEULA);

// Crypto ID - this is the id of the public key used
WCHAR szCryptoId[4];
szCryptoId[0] = L'\0';
swscanf_s(sDPid4.szAdvancedPid, L"XXXXX-00%3s-%*3s-%*6s-%*2s-%*4s-%*9s-%*7s", szCryptoId, 4);
Memo1->Lines->Append()"Crypto ID: " + (String)szCryptoId);
}
//unload library
FreeLibrary(hPidGenX);
return hResult;
}

Usage:

Code:

String key = Edit1->Text; // where "Edit1->Text" is the key in unicode
DecodeKey(key); // Show the magic
// End of the magic

You should change "Memo1->Lines->Append" to your function which will print results on output

Also, remember to change TCHAR map in compiler to wchar_t.

 

Sorry for the new post but I think it is major update for you.

I have reflected VAMT 2.0 and updated the DigitalProductId3 and DigitalProductId4 structures as follows:

Code:

struct DigitalProductId {
    unsigned int uiSize;
    unsigned short MajorVersion;
    unsigned short MinorVersion;
    char szProductId[24];
    unsigned int uiKeyIdx;
    char szEditionId[16];
    BYTE bCdKey[16];
    unsigned int uiCloneStatus;
    unsigned int uiTime;
    unsigned int uiRandom;
    unsigned int uiLt;
    unsigned int uiLicenseData[2];
    char sOemId[8];
    unsigned int uiBundleId;
    char sHardwareIdStatic[8];
    unsigned int uiHardwareIdTypeStatic;
    unsigned int uiBiosChecksumStatic;
    unsigned int uiVolSerStatic;
    unsigned int uiTotalRamStatic;
    unsigned int uiVideoBiosChecksumStatic;
    char sHardwareIdDynamic[8];
    unsigned int uiHardwareIdTypeDynamic;
    unsigned int uiBiosChecksumDynamic;
    unsigned int uiVolSerDynamic;
    unsigned int uiTotalRamDynamic;
    unsigned int uiVideoBiosChecksumDynamic;
    unsigned int uiCRC32;

};


struct DigitalProductId4 {
    unsigned int uiSize;
    unsigned short MajorVersion;
    unsigned short MinorVersion;
    WCHAR szAdvancedPid[64];
    WCHAR szActivationId[64];
    WCHAR szOemID[8];
    WCHAR szEditionType[260];
    BYTE bIsUpgrade;
    BYTE bReserved[7];
    BYTE bCDKey[16];
    BYTE bCDKey256Hash[32];
    BYTE b256Hash[32];
    WCHAR szEditionId[64];
    WCHAR szKeyType[64];
    WCHAR szEULA[64];
};

Now all the bytes of these structures are known but some of them are always just NULL so they are not that important.
I hope you like it

What is more, PidgenX's 4th argument is known now:

Code:

int PidGenX(string productKey, string configFile, string mpc, string oemId, [Out] DigitalProductId2 productId2, [In, Out] DigitalProductId3 productId3, [In, Out] DigitalProductId4 productId4);

where DigitalProductId2 is just a structure of one String so can be simply replaced with String.

@FreeStyler Basically you set "magicbyte" nr 42h in the buffer that return DigitalProductId,
loop decode and append N char if "magicbyte" is set.

My code is way more complicated but this is the most important thing I changed after Windows 8 CP release:

Code:

String prefix = StringReplace(Form5->XMLDocument1->DocumentElement->ChildNodes->First()->GetNodeName(), "Configurations", "", TReplaceFlags() << rfReplaceAll << rfIgnoreCase);

 //where `Form5->XMLDocument1->DocumentElement->ChildNodes->First()->GetNodeName()` is "pkc:Configurations" or "Configurations"

String configurations = prefix + "Configurations";
String actconfigid = prefix + "ActConfigId";
String editionid = prefix + "EditionId";
String productdescription = prefix + "ProductDescription";

Note that this is C++ VCL code.

The idea is simple:
Let's make a string named prefix. The prefix is everything that stays before "Configurations", "ActConfigId", etc. To check which prefix you should use, open the first node (named for ex. "pkc:Configurations") and assign to prefix its name with replaced "Configurations" with empty string -> prefix == "pkc:" for win7 or "" for win8.
Use prefix+your_node_name to open next XML nodes.
I hope you understand what I mean

 

Freestyler,

in my pidchecker i found that when using the build 8250 xrm-ms along with pidgenx.dll from that build i get the error.
if using the pidgenx.dll from build 8102 with the Win8CP xrm-ms there is no error.

I think we should create a single post with all the informations needed for coders - reading the whole topic may be a bit difficult, dont you think?

@FreeStyler, yep, I have done it just after the Windows 8 CP release
