Class netscape.security.x509.SubjectAlternativeNameExtension

   +----netscape.security.x509.SubjectAlternativeNameExtension

public class SubjectAlternativeNameExtension
extends Extension
implements CertAttrSet
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
