Overview#

In cryptography, a Cryptographic Key is a piece of information (a parameter) that determines the functional output of a cryptographic algorithm or cipher.

Without a Cryptographic Key, the algorithm would produce no useful result. In encryption, a Cryptographic Key specifies the particular transformation of plaintext into ciphertext, or vice versa during decryption.

Cryptographic Keys are also used in other cryptographic algorithms, such as digital Signature schemes and Message Authentication Codes.
