Hut 3 Administration and Typing room

Staff in the Administration and Typing Room typed up messages based on the deciphered messages. They sent them to MI6 and to the few other people authorised to receive them. To keep secret the fact that Enigma had been broken, these reports were made to appear as if they had been sent by a fictitious MI6 spy codenamed Boniface.
