The type of cryptography in which the same key is employed for each of the operations in the cryptosystem (e.g., encryption and decryption), and thus that same key, typically a secret, must be shared by the parties performing the various operations. See also block cipher, stream cipher, MAC algorithms, and (for the contrasting notion) asymmetric cryptosystem.

Equivalent names are conventional cryptosystem, secret key cryptosystem, classical cryptosystem, and private key cryptosystem.
