The Trust Store on iOS contains trusted root certificates that are preinstalled with iOS. These trusted root certificates are used to establish a chain of trust that is used to verify other certificates signed by the trusted roots, for example to establish a secure connection to a web server. When IT administrators create Configuration Profiles for iPhone, iPad, or iPod touch, these trusted root certificates do not need to be included. In iOS 7, the Trust Store may be updated from time to time. This article will be updated when changes are made. You can find the version of the Trust Store installed on your iOS device by tapping Settings > General > About. Scroll down to the bottom of the list to see the Trust Store version.
