Class CertificateIssuerExtension

java.lang.Object

com.tencent.kona.sun.security.x509.Extension

All Implemented Interfaces:

com.tencent.kona.sun.security.util.DerEncoder, java.security.cert.Extension

public class CertificateIssuerExtension
extends Extension

Represents the CRL Certificate Issuer Extension (OID = 2.5.29.29).

The CRL certificate issuer extension identifies the certificate issuer associated with an entry in an indirect CRL, i.e. a CRL that has the indirectCRL indicator set in its issuing distribution point extension. If this extension is not present on the first entry in an indirect CRL, the certificate issuer defaults to the CRL issuer. On subsequent entries in an indirect CRL, if this extension is not present, the certificate issuer for the entry is the same as that for the preceding entry.

If used by conforming CRL issuers, this extension is always critical. If an implementation ignored this extension it could not correctly attribute CRL entries to certificates. PKIX (RFC 5280) RECOMMENDS that implementations recognize this extension.

The ASN.1 definition for this is:

 id-ce-certificateIssuer   OBJECT IDENTIFIER ::= { id-ce 29 }

 certificateIssuer ::=     GeneralNames
