Cryptography (or cryptology) is a discipline of mathematics and, in modern times, of computer science concerned with information security and related issues, particularly encryption and authentication and other applications such as access control.

Cryptography, as an interdisciplinary subject, draws on several fields. Prior to the early 20th century, cryptography was chiefly concerned with linguistic patterns. Since then, the emphasis has shifted, and cryptography now makes extensive use of mathematics, including aspects of information theory, computational complexity, statistics, combinatorics, and especially number theory. Cryptography is a branch of engineering, but an unusual one as it deals with active, intelligent and malevolent opposition (see cryptographic engineering and security engineering). There is also active research examining the relationship between cryptographic problems and quantum physics (see quantum cryptography and quantum computing).

Cryptography is a central part of the techniques used in computer and network security for such things as access control and information confidentiality. Cryptography is used in many applications that touch everyday life; the security of ATM cards, computer passwords, and electronic commerce all depend on cryptography.

A reliable source informs me I'm mad (re: FluidRouter and cryptography for said project). I take this to be a good sign. #tweetfleet

Looks like Domain 5 (Cryptography) is the last set of "long" lectures, and Domain 6 (Organizational) is a bunch of short ones. *sigh*
