I created a new registry entries. I am not able to delete parent node. The structure of registry is as below:
HKEY_CURRENT_USER\Software\IE_BACKUP\Internet Settings
Below is the code I am using for deleting the registry entries. It deletes the content of the node InternetSettings but not able to delete IE_BACKUP.
void main()
{ //some other stuffs of code are here for creating new registry.
bool ret = DeleteValueKey(HKEY_CURRENT_USER, L"Software\\IE_BACKUP",L"Internet Settings");
}
bool DeleteValueKey(HKEY hKeyRoot, LPCWSTR Subkey, LPCWSTR ValueKey)
{
HKEY hKey = NULL;
bool bReturn = false;
if (RegDeleteKey(hKey, Subkey ) == ERROR_SUCCESS)
{
bReturn = true;
}
if (RegOpenKeyEx(hKeyRoot, Subkey, 0, KEY_SET_VALUE , &hKey) == ERROR_SUCCESS)
{
if (RegDeleteKey(hKey, ValueKey ) == ERROR_SUCCESS)
{
bReturn = true;
}
}
if(hKey != NULL){RegCloseKey(hKey);}
return bReturn;

I am trying to show credential provider for all local and for other user(Domain users) in signing options but I am not able to. I developed this credential provider taking reference from here. I made following changes in _EnumerateCredentials and GetCredentialCount functions of CSampleprovider.cpp file.
GetCredentialCount()
HRESULT GetCredentialCount([out] DWORD* pdwCount,
[out] DWORD* pdwDefault,
[out] BOOL* pbAutoLogonWithDefault)
{
*pdwDefault = CREDENTIAL_PROVIDER_NO_DEFAULT;
*pbAutoLogonWithDefault = FALSE;
if (_fRecreateEnumeratedCredentials)
{
_fRecreateEnumeratedCredentials = false;
_ReleaseEnumeratedCredentials();
_CreateEnumeratedCredentials();
}
DWORD dwUserCount;
HRESULT hr;
if (_pCredProviderUserArray != nullptr) {
hr = _pCredProviderUserArray->GetCount(&dwUserCount);
}
if ((dwUserCount == 0) || (IsOS(OS_DOMAINMEMBER) == 1)) {
dwUserCount += 1;//display additional empty tile
}
*pdwCount = dwUserCount;
return S_OK;
}
_EnumerateCredentials()
HRESULT CSampleProvider::_EnumerateCredentials()
{
HRESULT hr = E_UNEXPECTED;
DWORD dwUserCount;
if (_pCredProviderUserArray != nullptr)
{
//DWORD dwUserCount = 0;
_pCredProviderUserArray->GetCount(&dwUserCount);
if (dwUserCount > 0)
{
//_pCredential = new CSampleCredential*[dwUserCount];
for (DWORD i = 0; i < dwUserCount; i++) {
ICredentialProviderUser* pCredUser;
hr = _pCredProviderUserArray->GetAt(i, &pCredUser);
if (SUCCEEDED(hr))
{
//_pCredential[i] = new(std::nothrow) CSampleCredential();
_pCredential.push_back(new(std::nothrow) CSampleCredential());
if (_pCredential[i] != nullptr)
{
//logfile << "new CSampleCredential()\n";
hr = _pCredential[i]->Initialize(_cpus, s_rgCredProvFieldDescriptors, s_rgFieldStatePairs, pCredUser);
if (FAILED(hr))
{
_pCredential[i]->Release();
_pCredential[i] = nullptr;
}
}
else
{
hr = E_OUTOFMEMORY;
}
pCredUser->Release();
}
}
}
//if you are in a domain or have no users on the list you have to show "Other user tile"
if (DEVELOPING) PrintLn(L"IsOS(OS_DOMAINMEMBER): %d", IsOS(OS_DOMAINMEMBER));
if ((dwUserCount == 0) || (IsOS(OS_DOMAINMEMBER) == 1)) {
if (DEVELOPING) PrintLn(L"Adding empty user tile");
_pCredential.push_back(new(std::nothrow) CSampleCredential());
if (_pCredential[_pCredential.size() - 1] != nullptr) {
hr = _pCredential[_pCredential.size() - 1]->Initialize(_cpus, s_rgCredProvFieldDescriptors, s_rgFieldStatePairs, nullptr);
}
else {
if (DEVELOPING) PrintLn(L"Error adding user: %d", _pCredential.size());
}
}
return hr;
}
}
And I have changed a private header of type CSampleCredential to
std::vector<CSampleCredential> _pCredentialVector;
// SampleV2CredentialCSampleProvider.h
in CSampleProvider.h file.
When I tested this Credential provider of mine it is working fine i.e it is displaying for all local users in sign in options when no domain is added (No other user) but when domain is added(other user enabled) then I am being stuck at the welcome wallpaper and screen keeps on flickering.
So, How do I display my Credential provider for all local and domain users (Other user) in sign in options and over come that flickering of screen. I am new to this VC++ please help me out.
While I was trying to enable the custom credential provider to all the tiles including the other user tile I made few changes in GetCredentialCount() method and _EnumerateCredentials() method in SampleProvider.cpp file in Credential provider Sample given by Microsoft. The changes I made are:
HRESULT CServiceProvider::GetCredentialCount(
_Out_ DWORD *pdwCount,
_Out_ DWORD *pdwDefault,
_Out_ BOOL *pbAutoLogonWithDefault){
*pdwDefault = CREDENTIAL_PROVIDER_NO_DEFAULT;
*pbAutoLogonWithDefault = FALSE;
if (_fRecreateEnumeratedCredentials)
{
_fRecreateEnumeratedCredentials = false;
_ReleaseEnumeratedCredentials();
_CreateEnumeratedCredentials();
}
DWORD dwUserCount;
HRESULT hr;
if (_pCredProviderUserArray != nullptr) {
hr = _pCredProviderUserArray->GetCount(&dwUserCount);
}
if ((dwUserCount == 0) || (IsOS(OS_DOMAINMEMBER) == 1)) {
dwUserCount += 1;//display additional empty tile
}
*pdwCount = dwUserCount;
return S_OK;}
HRESULT CServiceProvider::_EnumerateCredentials(){
HRESULT hr = E_UNEXPECTED;
DWORD dwUserCount;
if (_pCredProviderUserArray != nullptr)
{
_pCredProviderUserArray->GetCount(&dwUserCount);
if (dwUserCount > 0)
{
//You need to initialize all the fields in LogonUI for each and every user
for (DWORD i = 0; i < dwUserCount; i++) {
ICredentialProviderUser* pCredUser;
hr = _pCredProviderUserArray->GetAt(i, &pCredUser);
if (SUCCEEDED(hr))
{
_pCredential.push_back(new(std::nothrow) CUserCredential());
if (_pCredential[i] != nullptr)
{
hr = _pCredential[i]->Initialize(_cpus, s_rgCredProvFieldDescriptors, s_rgFieldStatePairs, pCredUser);
if (FAILED(hr))
{
_pCredential[i]->Release();
_pCredential[i] = nullptr;
}
}
else
{
hr = E_OUTOFMEMORY;
}
pCredUser->Release();
}
}
}
//if you are in a domain or have no users on the list you have to show "Other user tile"
if ((dwUserCount == 0) || (IsOS(OS_DOMAINMEMBER) == 1)) {
_pCredential.push_back(new(std::nothrow) CUserCredential());
if (_pCredential[_pCredential.size() - 1] != nullptr) {
hr = _pCredential[_pCredential.size() - 1]->Initialize(_cpus, s_rgCredProvFieldDescriptors, s_rgFieldStatePairs, nullptr);
}
}
return hr;
}
return hr;
}
Now as you see we are sending nullptr as one of the argument while calling Initialize() method after checking if system is connected to domain, we need to handle that nullptr in Initialize() method by checking with if condition in SampleCredential.cpp file.
HRESULT CUserCredential::Initialize(CREDENTIAL_PROVIDER_USAGE_SCENARIO cpus,
_In_ CREDENTIAL_PROVIDER_FIELD_DESCRIPTOR const* rgcpfd,
_In_ FIELD_STATE_PAIR const* rgfsp,

HRESULT hr = S_OK;
_cpus = cpus;
_nNextScreenID = e_ARSNone;
GUID guidProvider;
LPOLESTR clsid;
if (pcpUser != nullptr) {
pcpUser->GetProviderID(&guidProvider);
StringFromCLSID(guidProvider, &clsid);
CoTaskMemFree(clsid);
_fIsLocalUser = (guidProvider == Identity_LocalUserProvider);
}
else {
_fIsLocalUser = true;//CP V1 or Domain
}
// Copy the field descriptors for each field. This is useful if you want to vary the field
// descriptors based on what Usage scenario the credential was created for.
for (DWORD i = 0; SUCCEEDED(hr) && i < ARRAYSIZE(_rgCredProvFieldDescriptors); i++)
{
_rgFieldStatePairs[i] = rgfsp[i];
hr = FieldDescriptorCopy(rgcpfd[i], &_rgCredProvFieldDescriptors[i]);
}
// Initialize the String value of all the fields.
if (SUCCEEDED(hr))
{

//Don't panic!!!
}
}

Using above code you can solve flickering (which is crashing of CP) as well as enable Credential provider for all user tiles.
I've written a credential provider and a key storage provider to logon to windows via certificate. As the documentation in this points is quite vague I used different samples from Microsoft to get things working.
I think I'm nearly there, but the logon behaves unpredictably. Sometimes I get through to the kerberos server (which complains about the certificate), sometimes the process fails with 0x80090029 without any information and sometimes windows crashes. As these crashes all have to do with access violations or null pointers and happen to occur in various places (kerberos.dll, Windows.UI.Logon.dll, ...) I think it has something to do with my key structure that i point the given NCRYT_KEY_HANDLE to in my OpenKey-implementation.
The KeyStorageProviderSample in the CNG-Kit has an example, but relies on a RSA-key stored in %AppData%. I don't have the private key available as it is stored in secure hardware, I just have the public part (i.e. the public certificate), that I read from another device and import via the following code:
SECURITY_STATUS WINAPI KeyHandler::ReadPemCert(__inout KSP_KEY *keyHandle)
{
LOG_FUNCTION;
CERT_CONTEXT certContext = {};
DWORD readLength = 0;
LOG("Fetch certificate");
const int maxSizeInBytes = 4096;
char pemCertificateAsBytes[maxSizeInBytes];
BluetoothClient bluetoothClient = BluetoothClient();
bluetoothClient.getCertificate((PBYTE)pemCertificateAsBytes, readLength);

certContext->pbCertEncoded = pcCertContext->pbCertEncoded;
certContext->dwCertEncodingType = pcCertContext->dwCertEncodingType;
CERT_INFO *certInfo;
certInfo = certContext.pCertInfo;

Somewhere in there must be the mistake leading to the various memory errors. But as I'm quite new to windows programming and c/c++ I just can't spot the point and can't find any documentation about the datastructure that windows expects for the NCRYTP_KEY_HANDLE.
Does anybody know more about this structure?
NCRYPT_KEY_HANDLE is just a pointer to a structure that you defined.
Windows itself doesn't care about this structure and expect that your provider knows how to work with it.
In KeyHandler::ReadPemCert you mixed legacy CryptoAPI and CNG API. Since you are implementing KSP you should use only CNG API (CryptImportPublicKeyInfoEx2).
