Each time a consumer requests access to an SSL-secured server, the server sends a duplicate from the certification to your customer. The SSL consumer checks this certificate (all web browsers come with an exhaustive listing of root certificates preloaded), and if the certification checks out, the server is authenticated plus the customer negotiates a symmetric-crucial cipher for use during the session. The session has become in an incredibly secure encrypted tunnel among the SSL server and also the SSL shopper.[fifty four]
