WebSession keys are sometimes called symmetric keys because the same key is used for both encryption and decryption. The session key is used for only one session. It is then discarded, and a new key is randomly generated for the next session. WebA session key is any symmetric cryptographic key used to encrypt one communication session only. In other words, it's a temporary key that is only used once, during one stretch of time, for encrypting and decrypting datasent between two parties; future conversations between the two would be encrypted with different session keys.
