Certificate trust settings

Trusting a certificate means that you authorise it to verify

web pages, e-mail servers, software packages, and other

data. Only trusted certificates can be used to verify services

and 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.
Before changing any certificate settings, you must make

sure that you really trust the owner of the certificate and

that the certificate really belongs to the listed owner.
