Demonstrates how to list the certificates in an Azure Key Vault.

Note: This example requires Chilkat v9.5.0.96 or later.

    // This requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    // We demonstrated how to get an access token for your Azure Key Vault
    // in this example: Azure Key Vault Get OAuth2 Access Token using Client Credentials

    // However.. starting in Chilkat v9.5.0.96, instead of directly providing Chilkat with the OAuth2 access token,
    // you can instead provide the means for Chilkat to automatically get the OAuth2 access token,
    // and in addition, Chilkat will automatically re-fetch a new OAuth2 access token as needed, such as shortly
    // prior to or after expiration.

    // You do this by setting the AuthToken property to a JSON string that contains the required information.

    const json = try chilkat.JsonObject.init();

    // The access token will be for Azure Key Vault operations.

    // automatically fetch the access token using the OAuth2 client credentials flow.
    http.setAuthToken(try json.emit(alloc));
