WebIn cryptography, a key is a piece of information (a parameter) that determines the functional output of a cryptographic algorithm or cipher. Without a key, the algorithm would produce no useful result. In encryption, a key specifies the particular transformation of plaintext into ciphertext, or vice versa during decryption. Key Exchange Web• Known plaintext – (plaintext, ciphertext) pair(s) • Chosen plaintext – Have plaintext encrypted, compare expected values Types of Cryptography • Public Key – Two keys: public & private • Symmetric Key (aka “Secret Key”) – One key: secret (but possibly shared) • Hash Functions – No keys
