What is cryptography? How algorithms keep information …

WebCryptography provides for secure communication in the presence of malicious third-parties—known as adversaries. Encryption uses an algorithm and a key to transform an input (i.e., plaintext) into an encrypted output (i.e., ciphertext). A given algorithm will always transform the same plaintext into the same ciphertext if the same key is used. WebCryptography. Jason Andress, in The Basics of Information Security (Second Edition), 2014. Symmetric key algorithms. Some of the cryptographic algorithms that are more recognizable to the general public are symmetric key algorithms. Several of these, such as DES, 3DES, and AES, are or have been in regular use by the US government and others as standard …
