Part of engineering the future of computer security. It is now widely recognized that you can't have computer security without crypto. (Can we have computer security with crypto? Different question, not so clear.) Cryptography is a huge field. Pure mathematics? Cipher implementation? Systems design using crypto? Hardware concerns involved when implementing crypto? Crypto vendor? Crypto consumer? Analyst of crypto systems (compliance, approval, etc)? And yeah, as your snarky interlocutor says, the IT guy that handles the "hard stuff" like certificate renewal[sarc]? The choices are so enormous that even "specializing in crypto" isn't much of a specialization at all!
