WebIn the classical symmetric-key cryptography setting, Alice and Bob have met before and agreed on a secret key, which they use to encode and decode message, to produce … WebKey in Cryptography. In 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.
