Cryptography

Computing portal

Here is a list of articles in the Cryptography category of the Computing portal that unifies foundations of mathematics and computations using computers.

Pages in this category should be moved to subcategories where applicable. This category may require frequent maintenance to avoid becoming too large. It should directly contain very few, if any, pages and should mainly contain subcategories.

Cryptography is the study of ways to convert information from its normal, comprehensible form into an obscured guise, unreadable without special knowledge — the practice of encryption. In the past, cryptography helped ensure secrecy in important communications, such as those of spies, military leaders, and diplomats. In recent decades, the field of cryptography has expanded its remit. Examples include schemes like digital signatures 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.
