I never realized it was a UK governemnt agency developing this !
https://www.gchq.gov.uk/ <- this is their website.[1]
[1] If you click on it they will be able to track you down via your IP address and super seekret cyberspy-fu. Just kidding. .... or am I? Actually I really am. I have no way of knowing either way. Or do I? I mean, how would you know? I really don't though. At least as far as you know.
Only if they know Visual Basic.
The official legit name of GC&CS was Government Code and Cypher School .. but IIRC at the time (1919 post WWI) the official name was coined it was putting out letterheads and contracts as G<something> Copper & Cable Services.
That's a dim recollection of what may have been one of many inside jokes | chuckles from WWII Bletchley as retold to an Australia some 30 odd years later so YMMV.
It's in keeping with keeping secrets from the general public & foreign agents via a Boring Name.
The British | Commonwealth WWII company front for their pre Manhatten Project nuclear programme was Tube Alloys .. so they did like a dull metals related cover name.
And The Manhattan Project was originally the "Manhattan Engineering District". Although that sounds a little bit exotic, at least to my ears.
