The key used in a symmetric algorithm. Since a secret key is used for both encryption and decryption, it must be shared between parties that are transmitting ciphertext to one another but must be kept secret from all unauthorized entities.

The cryptographic key used in a symmetric key algorithm, which results in the secrecy of the encrypted data depending solely upon keeping the key a secret, also known as a symmetric key.

A key known only to authorized parties. It can be used to authenticate the sender or recipient of a message. See secret key cryptography.

The key that should he kept Secret by its owner for encryption and decryption.

Part of a symmetric cipher in which the same key is used for encryption and decryption. SSL encryption uses a secret-key nested within a public key and authenticated through certificates. Secret-key encryption provides faster access than public-key encryption alone. See also public key cryptology.

a key known to both the sender and the recipient

a key that is shared between two parties in a cryptographic operation

a secret number that is used in the cryptographic calculations

Crypto key that is used in a secret key (" symmetric") algorithm. The secrecy of encrypted data depends solely on the secrecy of the secret key.

Key used in symmetric cryptograhy. Used only by a strictly defined, usually very small group of users, both for encryption and decryption.

The key used in a symmetric cryptosystem that is shared between the communicating parties.

A key whose value is not disclosed to unauthorized entities.

A single secret key which is used in conventional symmetric encryption which is used to encrypt and decrypt a message.

A cryptographic system that uses a single key for encrypting and signing data.

Secret key, also known as symmetric-key or shared-key, encryption is a ciphering technique by which two users exchange data by encrypting and decrypting data with a shared secret key. Data is both encrypted and decrypted with the same key. The secret key must be exchanged securely (such as through the "cones of silence") since anyone knowing the secret key can decrypt the data.

Confusingly sometimes used to mean the private key of a public key system, and also sometimes used (in contrast to "public key") to refer to a symmetric key system.

Key used both for ciphering and deciphering in symmetrical algorithms (also refereed to as secret keys).

Personal key to decrypt messages that were encoded using the public key.

An encryption key shared by a principal and the KDC, distributed outside the bounds of the system, with a long lifetime. In the case of a human user's principal, the secret key MAY be derived from a password.

Either the "private key" in public key (asymmetric) algorithms or the "session key" in symmetric algorithms.

An identical secret shared between two users of a secret key method.

In secret-key cryptography, this is the single key used both for encryption and decryption. Also called symmetric key. DES is a secret key algorithm
