Class Target

java.lang.Object

org.gudy.bouncycastle.asn1.ASN1Encodable

org.gudy.bouncycastle.asn1.x509.Target

All Implemented Interfaces:

ASN1Choice, DEREncodable

public class Target
extends ASN1Encodable
implements ASN1Choice

Target structure used in target information extension for attribute certificates from RFC 3281.

    Target  ::= CHOICE {
      targetName          [0] GeneralName,
      targetGroup         [1] GeneralName,
      targetCert          [2] TargetCert
    }

The targetCert field is currently not supported and must not be used according to RFC 3281.
