additional information. An application is only required to be able to evaluate an extension if it is
identified as critical. If an application does not recognize a critical extension, it must reject the

X.509v3 Certificate
YaST-Based PKI: YaST contains modules for the basic management of X.509 certificates. This
mainly involves the creation of CAs and their certificate. YaST provides tools for creating and
distributing CAs and certificates, but cannot currently offer the background infrastructure that allow
continuous update of certificates and CRLs. To set up a small PKI, you can use the available YaST
modules. However, you should use commercial products to set up an official or commercial PKI.
