public final class AuthorityKeyIdentifierExtension
extends X509CertificateExtension

This class provides an implementation of the authority key identifier X.509 certificate extension as described in RFC 5280 section 4.2.1.1. The OID for this extension is 2.5.29.35 and the value has the following encoding:

   AuthorityKeyIdentifier ::= SEQUENCE {
      keyIdentifier             [0] KeyIdentifier           OPTIONAL,
      authorityCertIssuer       [1] GeneralNames            OPTIONAL,
      authorityCertSerialNumber [2] CertificateSerialNumber OPTIONAL  }
 

The actual format of the key identifier is not specified, although RFC 5280 does specify a couple of possibilities.
