Measures reported by SSLCertTest
All SSL web servers are configured with security certificates. During the SSL protocol handshake with
clients, a server exchanges this certificate with the clients. An SSL certificate includes information about
the server/domain to which the certificate is licensed, the issuing authority, and a validity period for the
certificate. Beyond the validity period, the SSL certificate becomes invalid, and clients' SSL connections
to the web server would fail. To avoid such a situation, it is essential that web server administrators are
alerted in advance about the potential expiry of the SSL certificates on their web site. The SSLCertTest
monitors the validity period for SSL certificates of different web sites.
