(Mono C#) 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.

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

Chilkat.Secrets bootstrap = new Chilkat.Secrets();

// 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.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.
Chilkat.JsonObject json = new Chilkat.JsonObject();
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:
Chilkat.JsonObject jsonSecret = new Chilkat.JsonObject();
// 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.
bool success = bootstrap.UpdateSecretJson(json,jsonSecret);
if (success == false) {
    Debug.WriteLine(bootstrap.LastErrorText);
    return;
}

Debug.WriteLine("The Azure bootstrap secret has been stored.");
