Working with certificates

Use client and Certificate Authority (CA) digital certificates to enable HTC Desire 320
to access VPN or secured Wi-FI networks, and also to provide authentication to online
secure servers. You can get a certificate from your system administrator or download

Some apps such as your browser or email client let you install certificates directly in
the app. See the app's help for details.
