This article explains how to add a critical extension to a newly generated certificate in SafeGuard LAN Crypt Administration 3.80 and above.
The SafeGuard LAN Crypt Administration component can generate self-signed certificates. These certificates can only be used by SafeGuard LAN Crypt. The certificates also have a critical extension to show applications that they must not be used. These are simple certificates (comparable to Class-1 certificates) which comply with the X.509 standard.
In SafeGuard LAN Crypt you can configure whether or not a critical extension is added to a newly generated certificate or not.
