Your question is very unclear in various dimensions.
What do you mean by “encryption” ?
What do you mean by “built-in” ? If you mean built into openHAB then there’s many that OH can control.
But you need the proper hardware to run on (e.g. a 433 MHz RF stick or a ZWave controller) and HW is NOT part of OH.
Many people on this forum use ZWave w/ Fibaro or Qubino actuators to control their rollershutters.
