Manage certificates
Digital certificates protect your content when transferring
confidential information. Certificates should be used when
connecting to an online bank or another site, or to a remote
server for actions that involve transferring confidential
information.
Certificates should also be used when you want to reduce the
risk of viruses or other malicious software and be sure of the
authenticity of software when downloading and installing
software.

Digital certificates do not guarantee safety; they are used to
verify the origin of software.
Important: Even if the use of certificates makes the risks
involved in remote connections and software installation
considerably smaller, they must be used correctly in order to
benefit from increased security. The existence of a certificate
does not offer any protection by itself; the certificate
manager must contain correct, authentic, or trusted
certificates for increased security to be available. Certificates
have a restricted lifetime. If "Expired certificate" or
"Certificate not valid yet" is shown, even if the certificate
should be valid, check that the current date and time in your
device are correct.
