    // 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>"
    priv_key.savePkcs8File("keychain:MyEcdsaKey123") catch {
        std.debug.print("{s}\n", .{try priv_key.getLastErrorText(alloc)});
