'''Cryptography''' is the study of ways to convert [[information]] from its normal, comprehensible form into an obscured guise, unreadable without special knowledge &mdash; the practice of ''[[encryption]]''. In the past, cryptography helped ensure [[secrecy]] in important [[communication]]s, such as those of [[spy|spies]], [[military]] leaders, and [[diplomat]]s. In recent decades, the field of cryptography has expanded its remit. Examples include schemes like [[digital signature]]s and [[digital cash]], [[digital rights management]] for [[intellectual property]] protection, and securing [[electronic commerce]]. Cryptography is now often built into the [[infrastructure]] for [[computing]] and [[telecommunications]]; users may not even be aware of its presence.
