```elixir
@type t() :: %Common.Message.SetupSigning{
  initial_timestamp: XMAVLink.Types.uint64_t(),
  secret_key: [XMAVLink.Types.uint8_t()],
  target_component: XMAVLink.Types.uint8_t(),
  target_system: XMAVLink.Types.uint8_t()
}
```

Setup a MAVLink2 signing key. If called with secret_key of all zero and zero initial_timestamp will disable signing
