Re: Tommy Flowers
The reason it was kept secret was because the machines were still in use after WWII and British Intelligence wanted to be able to continue to intercept messages without anyone knowing that was possible.
Other, more sophisticated rotor-based machines like the Fialka were also developed that could be cracked using the same techniques.
However, the idea behind the machine could probably have been used without giving away where the idea had evolved or what it was used for.
