Question How do I use Windows Hello Authentication (Windows.Security.Credentials)

[JamesBowen]

Windows 10:
OpenEdge 12.8.

This is my code and I want to start using the "Windows Hello" as a form of Authenticator using biometrics and or PIN code.

using Progress.Lang.*.
using Windows.Security.Credentials.*.

block-level on error undo, throw.

class ABLWindowsHello:
    
    method public void MicrosoftPassportKeyCredentials(  ):
        
        define variable IsSupported as logical no-undo.
        
        wait-for KeyCredentialManager:IsSupportedAsync() set IsSupported.
        
        if IsSupported then
            message "Windows Hello is supported"
                view-as alert-box info.
        else
            message "Windows Hello is not supported"
                view-as alert-box info.
        
        return.

    end method.

end class.

The compile Error:


I can't seem to find the Windows.Security.Credentials assembly .dlls.

You can usually find assemblies on on nuget (https://nuget.info/packages) but it doesn't look like there's a Microsoft-published version on there. Or even a .net 4 version ...

Yes, this seems to be hidden deep as there is no indication of where it can be found. I do not know if what is posted here is any help:

I've given up trying to use the Windows Hello / Password. I don't know how to implement this into the ABL.

I'd recommend you to create an C# DLL and encapsulate the file inside your application... I did this to integrate our login system into Azure's authentication.

You'll require the following Nugets:

1. Microsoft.Windows.SDK.Contracts package. In the right pane of the NuGet Package Manager window select the desired version of the package based on the version of Windows 10 you want to target and click install.
2. Microsoft.NETCore.UniversalWindowsPlatform.

And inside the C# file you can do something like this:

namespace YourNamespace{

    public static class YourFile{

        public static string CheckWindowsHello() {

            string status;

            try {

                bool supported = await KeyCredentialManager.IsSupportedAsync();
                
                if (supported){
                    KeyCredentialRetrievalResult result =
                        await KeyCredentialManager.RequestCreateAsync("login", KeyCredentialCreationOption.ReplaceExisting);
                    if (result.Status == KeyCredentialStatus.Success){
                        status = $"SUCCESS - Logged in";
                    }
                    else{
                        status = $"ERROR - Login failed";
                    }
                } else {
                    status = $"ERROR - Windows Hello is not supported";
                }

            } catch (Exception e) {
                status = $"ERROR - Something wrong happened: {e}";

            }

            return status;
        }
    }
}

And call it by this inside your Progress program:

cStatus = YourNamespace.YourFile:CheckWindowsHello().
IF cStatus BEGINS "SUCCESS" THEN 
// DO YOUR CODE
ELSE ...
