Web Browser Security Warnings

You may have received an error or warning in your web browser about a site you visit not being secure.  This can happen for many reasons.  Usually, the fault lies with the web server because the server administrator has not been keeping up with the latest security best practices or has made a mistake in implementing a security measure.  Nevertheless, in a surprising number of cases, the cause can be a non-server issue, such as your machine's clock being off by more than several minutes, or from your using a free public WiFi service that has a captive login portal.
