Working of SSL

The SSL protocol exchange records. Each record can be optionally compressed, encrypted and packed with a Massage Authentication Code. Each code record has a “content type” field that specifies which upper level protocol i being used. When the connection begins, the record level another protocol the handshake protocol

Structure of send and receives several handshake :-

• It send a ClientHello massage specifying the list of chipher suites compression method and the highest protocol it supports.
• Then It receiver a ServerHello, in which the server chooses the connection parameters from the choices offered by the client.
• When the connection parameters are known, client and server exchange certificates
• The server can request a certificate from the client so that the connection can be mutually authentication.
