Which term denotes a piece of data used to encrypt or decrypt messages in cryptographic algorithms?

Explanation:
A cryptographic key is a piece of data used to transform plaintext into ciphertext and back again. In symmetric systems, the same key both encrypts and decrypts, while in asymmetric systems, a public key encrypts and a private key decrypts (or the reverse). This distinguishes it from cryptography as a whole, which is the study and practice of secure communication, and from cyberbullying or cyberwarfare, which are unrelated concepts. So, the data used to encrypt or decrypt messages in cryptographic algorithms is a cryptographic key.
