// See Global Unlock Sample for sample code.

// The bootstrap secret will contain the following information:

// AWS Region
// AWS Access Key
// AWS Secret Key

// or in the local manager (Windows Credentials Manager or Apple Keychain)
// Setup Bootstrap Secret in Local Manager
// Setup Bootstrap Secret in Memory

// 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.
