org.bouncycastle.asn1.x509

## Class Holder

- java.lang.Object
- - org.bouncycastle.asn1.ASN1Object
  - - org.bouncycastle.asn1.x509.Holder

- All Implemented Interfaces:
    ASN1Encodable, Encodable

      public class Holder
      extends ASN1Object

  The Holder object.

  For an v2 attribute certificate this is:

                  Holder ::= SEQUENCE {
                        baseCertificateID   [0] IssuerSerial OPTIONAL,
                                 -- the issuer and serial number of
                                 -- the holder's Public Key Certificate
                        entityName          [1] GeneralNames OPTIONAL,
                                 -- the name of the claimant or role
                        objectDigestInfo    [2] ObjectDigestInfo OPTIONAL
                                 -- used to directly authenticate the holder,
                                 -- for example, an executable
                  }

  For an v1 attribute certificate this is:

               subject CHOICE {
                baseCertificateID [0] EXPLICIT IssuerSerial,
                -- associated with a Public Key Certificate
                subjectName [1] EXPLICIT GeneralNames },
                -- associated with a name
