' The bootstrap secret will contain the following information:

' Azure Tenant ID
' Azure Client ID
' Azure Client Secret

' See following examples for setting up a bootstrap secret in memory, 
' or in the local manager (Windows Credentials Manager or Apple Keychain)
' Setup Bootstrap Secret in Local Manager
' Setup Bootstrap Secret in Memory
Dim bootstrap As New Chilkat.Secrets

' Set the location of the bootstrap secret.
' Can be "local_manager" or "memory", depending on how you setup the bootstrap secret.
' ---------------------------------------------------------------------------------------------
' If your operating system is NOT Windows or MacOS/iOS, then change "local_manager" to "memory"
' You can also, if desired, use "memory" on Windows and MacOS/iOS if your bootstrap secret was previously setup in memory.
' ---------------------------------------------------------------------------------------------
bootstrap.Location = "local_manager"

' Specify the bootstrap secret to be used.
Dim bsId As New Chilkat.JsonObject
bsId.UpdateString("appName","azure_bs")

Dim secrets As New Chilkat.Secrets

' Setup for the Azure Key Vault
secrets.Location = "azure_key_vault"
Dim success As Boolean = secrets.SetBootstrapSecret(bsId,bootstrap)

' Replace "kvChilkat" with the name of your key vault.
