A cryptographic key that is used with a (symmetric) cryptographic algorithm that is uniquely associated with one or more entities and is not made public. The use of the term “secret” in this context does not imply a classification level, but rather implies the need to protect the key from disclosure.

A single cryptographic key that is used with a symmetric-key algorithm; also called a secret key. A symmetric-key algorithm is a cryptographic algorithm that uses the same secret key for an operation and its complement (e.g., encryption and decryption).
