Jump to: navigation, search

In order to use many of the services offered on UABgrid, you will need to trust the UABgrid Certificate Authority (CA). This is accomplished by adding the UABgrid CA's root certificate to the list of trusted CAs recognized by your web browser or other client application

Contents

Background

From a systems perspective, the decision to trust (ie. import) the UABgrid CA is equivalent to deciding to "trust" a desktop computer by physically approaching it an launching application links presented in it's menus. The trust expressed through physical proximity and visual familiarity with your desktop system is expressed electronically via the PKI infrastructure leveraged by UABgrid.

A dialog will pop up warning you that this certificate is unknown. This dialog is the actual import step. This dialog also uses very strong wording urging caution. This warning is saying that once you trust this CA, IE will no longer warn you about sites that use certificates issued by the UABgrid CA. This is what we want to achieve. But to assure you are actually looking at the real UABgrid CA, you should confirm that the "Thumprint" number shown in the middle of the dialog contains the unique signature of the "UABgrid CA v1.0": (sha1): DDBB73C6 0FE21B5B B1DAE981 C8D5B502 C0861431 If the Thumbprint is correct, you may click "Yes" to complete the import.
