   What most people didn't realize was that the controversy was due to the
   fact that rotor-driven cipher machines had been continued to be sold in
   the post-WWII era, without their weakness being recognized.  This
   allowed the CIA/GCHQ to continue to decrypt enciphered messages for
   decades afterwards.
