Certificate manager

Select Menu > Ctrl. Panel > Settings > General > Security > Certificate
management.
Digital certificates are used to verify the origins of software but do not guarantee
safety. There are a number of different types of certificates available:
1. Authority certificates
1. Trusted site certificates
2. Personal certificates
3. Phone certificates
During a secure connection, a server may send a server certificate to your device.
Upon receipt, it is checked through an authority certificate stored in your device. You
receive notification if the identity of the server is not authentic or if you do not have the
correct certificate in your device.
You can download a certificate from a web site, or receive a certificate as a message.
Certificates should be used when you connect to an online bank or a remote server
to transfer confidential information. They should also be used if you want to reduce
the risk of viruses or other malicious software, and to check the authenticity of the
software when you download and install software to your device.
TIP: When you add a new certificate, check its authenticity.
