Net iD Client allows you to create custom extensions for a web browser, which can be used for making websites more secure. This extension requires Net iD Client to be installed on the computer. The functionality depends on the configured access level in Net iD Client. The lowest access level allows the creation of digital signatures and the highest level is necessary for the creation of security tokens. It is also possible to use this extension with a desktop application that supports communication with a browser through a special interface. This extension is only applicable to users with Net iD Client installed and this extension enabled.
