OpenAsync(String)

Edit

Retrieves a key credential for the current user and application.

public:
 static IAsyncOperation<KeyCredentialRetrievalResult ^> ^ OpenAsync(Platform::String ^ name);

/// [Windows.Foundation.Metadata.RemoteAsync]
 static IAsyncOperation<KeyCredentialRetrievalResult> OpenAsync(winrt::hstring const& name);

[Windows.Foundation.Metadata.RemoteAsync]
public static IAsyncOperation<KeyCredentialRetrievalResult> OpenAsync(string name);

function openAsync(name)

Public Shared Function OpenAsync (name As String) As IAsyncOperation(Of KeyCredentialRetrievalResult)

Parameters

name: String
Platform::String

winrt::hstring

The name of the key credential to open.

Returns

IAsyncOperation<KeyCredentialRetrievalResult>

When this method completes, it returns the results of the key credential retrieval.

Attributes: RemoteAsyncAttribute

Remarks

The OpenAsync method retrieves an existing key credential. The retrieved key can be used for cryptographic operations such as signing and encryption.

Key Usage

The key is an RSA 2048-bit key. It supports operations like:

Generating signatures in PKCS #1 RSA PSS format with SHA256.
Encrypting data using appropriate padding schemes such as PKCS #1 OAEP.
