The Secure Sockets Layer which relies on for encrypting the data between client and server

symmetric encryption

Explanation:

The Secure Sockets Layer (SSL) protocol is required by the Web servers and the web browsers in order to protect the data of the users during transfer through the creation of an encrypted channel that is unique for private communications that occur over the Internet.

The Secure Sockets Layer relies on the encryption in order to secure the link that exists between the client and the server which is the website.

This implies that the encryption and also the decryption of the data will be done using a cryptographic key that is shared. The cryptographic key will be generated and shared on accordance with transport layer security handshake.
