Phone certificates — View and edit device certificates.
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.
View certificate details — check authenticity
You can only be sure of the correct identity of a server when the signature
and the validity period of a server certificate have been checked.
You are notified if the identity of the server is not authentic or if you do not
have the correct security certificate in your device.
To check the details of a certificate, select Options Certificate details. The
>
validity of the certificate is checked, and one of the following notes may be
displayed:
Certificate not trusted — You have not set any application to use the
certificate.
Expired certificate — The certificate validity period has ended.
Certificate not valid yet — The certificate validity period has not yet begun.
Certificate corrupted — The certificate cannot be used. Contact the
certificate issuer.
