Class Overview

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).
