CertAid manages the entire certificate setup procedure for Safari browsers on Mac OS X 10.5 (Leopard), 10.6 (Snow Leopard), and Mac OS X 10.7 (Lion) giving users a more reliable installation experience.
The setup procedure includes installing the MIT CA as well as the user's personal certificate, optionally deleting old certificates, and setting the correct identity preferences via a single, graphical application. If you need to retain access to old user certificates, e.g., for access to encrypted mail, you should not delete them.
