Class SubjectAlternativeNameExtension

java.lang.Object

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

com.tencent.kona.sun.security.x509.SubjectAlternativeNameExtension

All Implemented Interfaces:

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

public class SubjectAlternativeNameExtension
extends Extension

This represents the Subject Alternative Name Extension. This extension, if present, allows the subject to specify multiple alternative names.

Extensions are represented as a sequence of the extension identifier (Object Identifier), a boolean flag stating whether the extension is to be treated as being critical and the extension value itself (this is again a DER encoding of the extension value).

The ASN.1 syntax for this is:

 SubjectAltName ::= GeneralNames
 GeneralNames ::= SEQUENCE SIZE (1..MAX) OF GeneralName
