Windows 10 凭据提供者 C#

Question

I am working on implementing a Credential Provider in C#.

I have downloaded the V2 Credential Provider sample in C++, which is for Windows 8, and managed to make it work on my Windows 10 PC. I also looked into this credential provider implementation in .NET https://github.com/SteveSyfuhs/CredProvider.NET , but this is for the CredUI scenario.

I have managed to make my credential provider to be displayed under "Sign-in options" of a user's tile, but now I would like to implement the login part.

I have to implement the GetSerialization method for the Logon/Unlock scenario. In the C++ sample this is already implemented, but I have troubles "translating" it into C# code, since I am not familiar with C++.

Does anyone know where I could find a working implementation of this method in C# for the Logon/Unlock scenario? Any help would be very appreciated.

Answer 1

I see that you're familiar only with C# and you want to use that only for the CP you're working on.
I have worked on CP with c++ though I would have preferred to use C# too which am more agile with.

Implementing the Lock/Unlock isn't fully implemented in the C++ sample as you expressed. You have to intercept the code in the right place to add additional rules/ features in your project. Anyway, you can paste some codes and let's look into it together.

Answer 2

You have to write KerbInteractiveUnlockLogonInit and KerbInteractiveUnlockLogonPack methods in C++ and use it with DllImport from your C# project. According to CREDENTIAL_PROVIDER_USAGE_SCENARIO, you need to set MessageType property of KERB_INTERACTIVE_LOGON struct. You can get methods from here .
