Cryptography cryptography

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 … See more Symmetric-key cryptography Symmetric-key cryptography refers to encryption methods in which both the sender and receiver … 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," a story by Edgar Allan Poe.
