Instructions for trusting all the CatCert certificates permanently installed on various websites.

If you download and install the public keys for the CatCert certificate, it will be installed on the root of your browser. On subsequent visits to the IRL virtual office or to other websites that have a CatCert certificate installed it will not be necessary to validate the certificate again.

How should I configure the certificates on a Mac?

To be able to sign documents on a computer using the MAC OS X system, you should install the certificates through the Keychain app. This is the default application for the management of the certificates. So, if you double click on a certificate file, it will be installed there.
