HTTPS is not a protocol itself but it actually refers to HTTP communication over SSL Secure Sockets Layer connection HTTPS uses public key cryptography to protect the communication With HTTPS the server sends back its identification in the form of a digital certificate The certificate usually contains the server name the trusted certificate authority CA and the server s public encryption key The server certificate includes a digital signature from a certification authority Each browser is normally equipped with a set of CA root certificates of commercial authorities The web browsers perform a set of verifications over the digital certificate in order to validate the certificate and start the HTTPS communication The main checks are substantially the following e The client verifies that the issuing Certificate Authority CA is on its list of trusted CAs e The client checks the server s certificate validity period Further to this the client may compare the actual DNS name of the server to the DNS name on the certificate though this last point may be browser dependent Below is a sample of the results of these checks when browser attempts to establish an HTTP connection to the web server embedded in the SNMP Web adapter the sample is take from Internet Explorer but similar indications can be obtained with the most common browsers Security Alert j x Information you exchange with this site cannot be viewed or changed by others
