Definition of cryptography
WebApr 30, 2014 · Cryptography is the science of information security. The word is derived from the Greekkryptos, meaning hidden. Cryptography is closely related to the disciplines of cryptology andcryptanalysis. Cryptography includes techniques such as microdots, merging words with images, and other ways to hide information in storage or transit. WebCryptography based on industry-tested and accepted algorithms, along with key lengths that provide a minimum of 112-bits of effective key strength and proper key-management practices. Cryptography is a method to protect data and includes both encryption (which is reversible) and hashing (which is “one way”; that is, not reversible). ...

WebCryptography began with ciphers, the first of which was the Caesar Cipher. Ciphers were a lot easier to unravel compared to modern cryptographic algorithms, but they both used keys and plaintext. Though simple, ciphers from the past were the earliest forms of encryption. Today’s algorithms and cryptosystems are much more advanced. WebThe encrypting (scrambling) of data into a secret code. Cryptography is used to conceal messages transmitted over public networks such as the Internet (see HTTPS).
