Class IssuerAlternativeNameExtension

  • All Implemented Interfaces:
    java.io.Serializable, CertAttrSet

    public class IssuerAlternativeNameExtension
    extends Extension
    implements CertAttrSet
    This represents the Issuer Alternative Name Extension. This extension, if present, allows the issuer 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).
