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
