I work in a defense company. Until now, some secret tasks are rotating on SM. A security specialist - a grandfather about 70 years old - comes and checks the presence of seals, etc. Takes an e/m coil with data, exhausts it, gets a lump, looks into the tape for a long time and gives out in full seriousness: "Bl...! They know how to encrypt now!" He puts a coil on the shelf and leaves.
