the client and the server agree to use the TLS protocol, they negotiate a stateful connection to transfer the data by using a handshake process. By shaking hands, the client and server negotiate various parameters for creating a secure connection:When a client connects to a server that supports the TLS protocol, it requires the creation of a secure connection and lists the supported password combination handshake to start.The server determines the encryption and hashing functions from this list

OpenSSL provides a powerful feature in this area, and is open source, now widely used in the network communication mechanism;3. By deploying a CA (Certificate authority) server within a certain scope, the certificate authentication and authorization can be realized in the LAN, and the security of data transmission can be ensured, and the working principle of the international large CA institution may be un

Computer Associates International, Inc (CA) recently announced that it won the best application/Management System Award at the Linux World China 2004 Conference. This shows that CA has once again affirmed its efforts to promote the development of Linux and open source communities. With the development and maturity of Linux, more and more enterprises begin to apply open-source software.
