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

' The bootstrap secret will contain the following information:

' IBM Cloud API Key

' 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","ibm_bs")
bsId.UpdateString("service","Example")
bsId.UpdateString("username","Joe")

' ----------------------------------------------------
Dim secrets As New Chilkat.Secrets

' Setup for the IBM Cloud Secrets
secrets.Location = "ibm_cloud"
Dim success As Boolean = secrets.SetBootstrapSecret(bsId,bootstrap)
If (success = False) Then
    Debug.WriteLine(secrets.LastErrorText)
    Exit Sub
End If


' Specify the secret to be fetched.
Dim json As New Chilkat.JsonObject
json.UpdateString("appName","Test2")
json.UpdateString("service","Custom")
json.UpdateString("domain","Ocean")
json.UpdateString("username","Starfish")

' You'll also need to specify your IBM Cloud instance ID and region for each API call.
json.UpdateString("instance_id","a88a0c56-50a6-4461-9911-345b173e1171")
json.UpdateString("region","us-south")

' Get the binary secret data.
Dim bd As New Chilkat.BinData
success = secrets.GetSecretBd(json,bd)
If (success = False) Then
    Debug.WriteLine(secrets.LastErrorText)
    Exit Sub
End If


' For our testing, the binary secret was a JPG image..
bd.WriteFile("c:/temp/qa_output/starfish.jpg")

Debug.WriteLine("Success.")
