Details
The HTTP protocol is a stateless protocol. To maintain a session, a session identifier is used. The session identifier is a piece of data used to identify a session and a user. If the session identifier is compromised by an attacker, the session can be hijacked. By encrypting the session identifier, the identifier becomes more difficult for an attacker to hijack, decrypt, and use before the session has expired.
