CommisSignCommisSign Certification Authority (CA)

The CommisSign web site allows external partners of the European Commission to install the root and intermediate certificate of CommisSign on their PCs and thus validate the certificates issued by that Certification Authority to Commission officials.

In order to use the root certificate you should first view our Certificate Practice Statement (CPS).

In order to install the CommisSign root certificate please first specify the format you want to use for downloading. Please note that not all formats are understood from all browsers. Generally, the X.509 formats are more widely used.
