Cryptographic hash functions are cryptographic algorithms that generate and use keys to encrypt data, and such functions may be viewed as keys themselves. They take a message of any length as input, and output a short, fixed-length hash , which can be used in (for example) a digital signature. 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 share the same key (or, less commonly, … See more Prohibitions Cryptography has long been of interest to intelligence gathering and law enforcement agencies. … 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. Until modern times, cryptography referred almost exclusively to "encryption", which is the process of … See more 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 … See more • Collision attack • Comparison of cryptography libraries • Crypto Wars – Attempts to limit access to strong cryptography See more WebA cryptogram is a type of puzzle that consists of a short piece of encrypted text.
