Key or Cryptographic Key or Cryptovariable: A piece of data used as input for an encryption algorithm to transform plaintext data into ciphertext or vice versa. The key determines the specific output of an encryption algorithm, thus ensuring that only those who possess the correct key can decrypt the data. Keys are used in a variety of contexts, including secure communication, data protection, and digital signatures.
