Class NetscapeCertTypeExtension

java.lang.Object

sun.security.x509.Extension

sun.security.x509.NetscapeCertTypeExtension

All Implemented Interfaces:

CertAttrSet<java.lang.String>

public class NetscapeCertTypeExtension
extends Extension
implements CertAttrSet<java.lang.String>

Represents Netscape Certificate Type Extension. The details are defined here .

This extension, if present, defines both the purpose (e.g., encipherment, signature, certificate signing) and the application (e.g., SSL, S/Mime or Object Signing of the key contained in the certificate. This extension has been superseded by IETF PKIX extensions but is provided here for compatibility reasons.
