Class UnknownExtension

java.lang.Object

iaik.x509.V3Extension

iaik.x509.UnknownExtension

public class UnknownExtension
extends V3Extension

This class implements any unknown extension. It tries to show as much information as possible about the extension.

An Unknown Extension is an extension that cannot be handled properly by the actual certificate (CRL) management software. Within the iaik.X509 environment an extension is treated as unknown if there exists no registered implementation for the extension in mind.

If the certificate handling software detects an unknown extension, it has to check if this extension is labelled as being critical or not. A certificate containing an unknown critical extension shall be rejected. Any non-critical unknown extension can be ignored.

If the CRL handling software detects an unknown extension, it has to check if this extension is labelled as being critical or not. The validation of a CRL containing an unknown critical extension must fail. Any non-critical unknown extension can be ignored.
