Entertainingly, he’s entering the field from mathematical cryptography; so “don’t design your own cipher” is precisely the wrong analogy to use here :-)
It used to be the domain of the linguists… But you’re correct; nowadays, I’m using mathematical cryptography as a short hand for “y’know, like, real cryptography, not just messing around with symbols to impress you friends”.

“mathematical cryptography”? What other sort of cryptography is there?

Ah, OK!
It’s possible in that case that I may actually know your friend, if they happened to touch on some of the same parts of the field as me.
No extra clues :-)
