// 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:

// Doppler Token

// 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
CkoSecrets *bootstrap = [[CkoSecrets alloc] init];

// 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.

// Setup for the Doppler Secrets

// You'll also need to specify your Doppler project and config names for each API call.

// Get the binary secret data.
