When you log on to an SBH for the first time, your web browser instantly switches to a secure port (Port 443). A secure port requires certificates that authenticate it as a trusted site. With Google Chrome, the URL you entered appears with a red slash.
The https:// means you are communicating with a secure port. The red slash through https:// means the site is not a trusted site. An error appears in the browser and prompts you to continue to the site even though it is not secure. Different browsers provide a similar action as Google Chrome. You can continue to the site and log in knowing that the security required for this port has not been configured.
To connect to a secured site, you must add a certificate that is private or public. The purpose of the certificate is to configure a chain of trust. You must set up the public or private keys in order to set up a chain of trust. These keys make sure that the site trusts your device.
