WebCryptanalysis is the process of studying cryptographic systems to look for weaknesses or leaks of information. Cryptanalysis is generally thought of as exploring the weaknesses of the underlying mathematics of a cryptographic system but it also includes looking for … General Cryptography is widely used on the internet to help protect user-data and prevent eavesdropping. To ensure secrecy during transmission, many systems use private key cryptography to protect transmitted information. With public-key systems, one can maintain secrecy without a master key or a large number … See more Cryptography, or cryptology (from Ancient Greek: κρυπτός, romanized: kryptós "hidden, secret"; and γράφειν graphein, "to write", or -λογία -logia, "study", respectively ), is the practice and study of techniques for secure communication See more Before the modern era, cryptography focused on message confidentiality (i.e., encryption)—conversion of messages from a comprehensible form into an incomprehensible one and back again at the other end, rendering it unreadable by interceptors or … See more Prohibitions Cryptography has long been of interest to intelligence gathering and law enforcement agencies. … See more • Collision attack • Comparison of cryptography libraries • Crypto Wars – Attempts to limit access to strong cryptography See more The first use of the term "cryptograph" (as opposed to "cryptogram") dates back to the 19th century—originating from "The Gold-Bug," … See more Symmetric-key cryptography Symmetric-key cryptography refers to encryption methods in which both the sender and receiver share the same key (or, less commonly, in which their keys are different, but related in an easily computable way). … See more • Arbib, Jonathan; Dwyer, John (31 January 2011).
