New description:

 Right now, our Tor controllers will send any file readable by the user to
 whatever is listening to the control port they try to connect to (usually
 127.0.0.1:9051).  This sucks.  They should only send any file that is
 exactly 32 bytes long and readable by the user to whatever is listening on
 that port.  (Hopefully no one stores AES-256, Salsa20, or Curve25519
 secret keys (or other actually sensitive pieces of data) in raw 32-byte
 binary files.)
