The handshake protocol is a fundamental part of network security, specifically in the context of establishing secure communication channels between clients and servers. It is the initial process where both parties exchange information to authenticate each other and agree on encryption methods for a secure communication session. The protocol begins when a client, such as a web browser, sends a request to a server to initiate a secure connection. This request typically includes a list of supported encryption algorithms and the highest version of the SSL/TLS protocol it can support. Upon receiving this request, the server responds with its own set of supported encryption methods and selects the most secure one that both the client and the server can use. This mutual agreement on the cipher suite ensures that both parties will use the same method to encrypt and decrypt the
