Gentlemen, gentlemen, please!

Cryptology is NOT the same as cryptography.

Cryptography is a very specialized, and advanced, subfield of cryptology.

Cryptology   is the field of communications security.
Cryptography is the field of codes and ciphers.

Physical security, speech privacy systems, traffic analysis, and
navigational beacon deception ("meaconing") are four sample cryptologic
topics that do not involve cryptography.

I was employed for five years as a "cryptologic linguist".  My duties
had little, if anything, to do with "cryptography".

The distinction between cryptography and cryptology is current (circa
1982) and official (US DoD definitions for official publications).
