SSL/TLS Handshake between Server and Client
In today's communication over the internet mostly servers and client communication are using secure communication and that's HTTPs not HTTP. To make this communication secure we use a protocol that is part of session layer (TCP OSI layer) TLS (Transport layer security) before a TCP session is initiated for data flow between a client and server TLS/SSL handshake is a must for HTTPs enabled servers. We will just discuss the type of SSL handshake without going into the details of its process. In SSL handshake process server and client can share their respective certificates (chain of certificates) signed by CA authorities or it can be signed locally (that communication will be only between trusted sources not for everyone over the internet. After receiving the certificate at client and server end respective nodes will verify the certificates either via root CA or via locally CA store certificates (if communication is only in between trusted parties).
