Azure Key Vault - Setup Bootstrap Secret in Local Manager

See more Secrets Examples

Accessing a cloud-based secrets manager requires authentication credentials, which cannot be stored in the manager itself. Instead, they must be securely stored locally.

One solution is to store the authentication credentials as a secret in the Windows Credentials Manager or Apple Keychain. These credentials serve as the "bootstrap secret" for authenticating with the cloud-based secrets manager.

This example demonstrates how to setup a bootstrap secret for the Azure Key Vault.

Note: This example requires Chilkat v10.1.0 or later.

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.
package com.test;

import android.app.Activity;
import com.chilkatsoft.*;

import android.widget.TextView;
import android.os.Bundle;

public class SimpleActivity extends Activity {

  private static final String TAG = "Chilkat";

  // Called when the activity is first created.

    boolean success = false;

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

    CkSecrets bootstrap = new CkSecrets();

    // We're going to store the bootstrap secret in the local manager.
    // On Windows, this is the Windows Credentials Manager
    // On MacOS/iOS, it is the Apple Keychain
    bootstrap.put_Location("local_manager");

    // Specify the name of the bootstrap secret.
    // service and username are required.
    // appName and domain are optional.
    // Note: The values are arbitrary and can be anything you want.
    CkJsonObject json = new CkJsonObject();
    json.UpdateString("appName","azure_bs");
    json.UpdateString("service","Example");
    json.UpdateString("username","Joe");

    // The bootstrap secret for the Azure Key Vault will contain
    // the tenant_id, client_id, and client_secret, like this:
    CkJsonObject jsonSecret = new CkJsonObject();
    // Modify to your values.
    jsonSecret.UpdateString("tenant_id","YOUR_TENANT_ID");
    jsonSecret.UpdateString("client_id","YOUR_CLIENT_ID");
    jsonSecret.UpdateString("client_secret","YOUR_CLIENT_SECRET");

    // Create or update the bootstrap secret.
    success = bootstrap.UpdateSecretJson(json,jsonSecret);
    if (success == false) {
        Log.i(TAG, bootstrap.lastErrorText());
        return;
        }

    Log.i(TAG, "The Azure bootstrap secret has been stored.");
