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

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

    // 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.

    CkJsonObject json = new CkJsonObject();
    json.UpdateString("client_id","APP_ID");

    // The APP_PASSWORD is the "password" returned by the Azure CLI command: az ad sp create-for-rbac --name http://example.com --role Contributor
    // See Azure Key Vault Get OAuth2 Access Token using Client Credentials
    json.UpdateString("client_secret","APP_PASSWORD");

    // The access token will be for Azure Key Vault operations.
    json.UpdateString("resource","https://vault.azure.net");

    // Specify the token endpoint which includes your tenant ID.
    json.UpdateString("token_endpoint","https://login.microsoftonline.com/TENANT_ID/oauth2/token");

    CkHttp http = new CkHttp();

    // Instead of providing an actual access token, we give Chilkat the information that allows it to 
    // automatically fetch the access token using the OAuth2 client credentials flow.
    http.put_AuthToken(json.emit());

    // Replace key_vault_name with the name of your Azure Key Vault.
    CkStringBuilder sbResponse = new CkStringBuilder();
