Cryptography is the study of ways to convertinformation from its normal, comprehensible form into an obscured guise, unreadable without special knowledge — the practice ofencryption. In the past, cryptography helped ensuresecrecy in importantcommunications, such as those ofspies,military leaders, anddiplomats. In recent decades, the field of cryptography has expanded its remit. Examples include schemes likedigital signatures anddigital cash,digital rights management forintellectual property protection, and securingelectronic commerce. Cryptography is now often built into theinfrastructure forcomputing andtelecommunications; users may not even be aware of its presence.
