Wouldn't landing a spacecraft next to the first one allow you to decrypt messages in essentially one round trip time? So if you had a message on earth timed locked for 100 years you could transmit it your your own spacecraft next to the decrypting spacecraft and it could almost immediately get through all layers of encryption and send you back the decrypted message.
