  //  In Apple Keychain, the label for an item such as a private key is a user-friendly identifier that helps distinguish one item from
  //  another in the Keychain. It is typically a brief name or description associated with the item. 
  //  The label is displayed in the Keychain Access application and is useful for quickly identifying the purpose
  //  or source of a specific key, certificate, or password entry.

  //  The label does not affect the functionality or security of the item; it is purely for organizational purposes. 
  //  You can edit or assign labels to make your Keychain easier to navigate.

  //  On MacOS, you can save the private key to the Keychain by calling SavePkcs8File with a "filename" in the format"keychain:<label>"
