To determine what specific algorithms to use, the client and the web server start by mutually deciding on the cipher suite to be used.Ĭipher suites are required because of the variety of servers, operating systems and browsers. These ciphers are required at various points of the connection to perform authentication, key generation and exchange, and a checksum to ensure integrity. A hash/MAC function, which determines how data integrity checks will be carried out. ![]() A bulk encryption cipher, which is used to encrypt the data.An authentication or digital signature algorithm, which dictates how server authentication and client authentication (if required) will be implemented.A key exchange algorithm, to determine how symmetric keys will be exchanged.During the handshake, the client and the web server will use: As we said before, the SSL handshake is a complicated process, because it leverages a variety of cryptographic functions to achieve the HTTPS connection.
