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.
