(Visual FoxPro) Azure Key Vault - Setup Bootstrap Secret in Memory

See more Secrets Examples

Accessing a cloud-based secrets manager requires authentication credentials, which cannot be stored within the secrets manager itself.

This example shows how to set up an in-memory bootstrap secret with authentication credentials which will be used in other examples to access 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.

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Secrets')
loBootstrap = CreateObject('Chilkat.Secrets')

* This secret will reside in memory.
loBootstrap.Location = "memory"

* 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.
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject')
loJson = CreateObject('Chilkat.JsonObject')
loJson.UpdateString("appName","azure_bs")
loJson.UpdateString("service","Example")
loJson.UpdateString("username","Joe")

* The bootstrap secret for the Azure Key Vault will contain
* the tenant_id, client_id, and client_secret, like this:
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject')
loJsonSecret = CreateObject('Chilkat.JsonObject')
* Modify to your values.
loJsonSecret.UpdateString("tenant_id","YOUR_TENANT_ID")
loJsonSecret.UpdateString("client_id","YOUR_CLIENT_ID")
loJsonSecret.UpdateString("client_secret","YOUR_CLIENT_SECRET")

* Create or update the bootstrap secret (in memory).
* The secret is stored encrypted in memory, and is available to be used
* regardless of the lifetime of the "bootstrap" object.
