1. The "nearer Yes" answers may be correct for published crypto (PGP and so on). But what about the possibility that someone is using a private cipher BEFORE the text enters some public system or another? A book cipher comes to mind (see https://en.wikipedia.org/wiki/Beale_ciphers for an example....it gives you an idea about what's going on, even if the Beale papers are a hoax).

2. Even if GCHQ is actually listening to real time conversations (whether point-to-point or group), what if the conversations are conducted using pre-agreed code words? A recent NFL program showed quarterbacks instructing the team with actor's names -- Halle Berry was one of the calls!

So...here's a real book cipher example....readers feel free to publish the plain text.
