What is a Security Certificate?

Install the NIU security certificate in your browser

A security certificate is the key to decrypt encrypted messages by an authenticated message receiver. NIU uses the Secure Socket Layer (SSL) for transmitting and accepting secure information (such as passwords) and for encrypting entire sessions that contain confidential information. SSL is a standard method for protecting web communications by providing message encryption and authentication.

By accepting the NIU certificate you add NIU to the list of trusted certificating authorities your computer acknowledges and approves.

Installing the NIU security certificate will prevent warning messages from being displayed by NIU web-based applications requiring authentication. Since (in general) browsers do not share data, a certificate installed into Internet Explorer will not work for Firefox and vice-versa.
