old.org.bouncycastle.cert.AttributeCertificateHolder

All Implemented Interfaces:

Cloneable, Selector

public class AttributeCertificateHolder
extends Object
implements Selector

The Holder object.

          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
          }
 

Note: If objectDigestInfo comparisons are to be carried out the static method setDigestCalculatorProvider must be called once to configure the class to do the necessary calculations.

AttributeCertificateHolder

public AttributeCertificateHolder(int digestedObjectType,
                                  String digestAlgorithm,
                                  String otherObjectTypeID,
                                  byte[] objectDigest)

Constructs a holder for v2 attribute certificates with a hash value for some type of object.

digestedObjectType can be one of the following:

• 0 - publicKey - A hash of the public key of the holder must be passed.
• 1 - publicKeyCert - A hash of the public key certificate of the holder must be passed.
• 2 - otherObjectDigest - A hash of some other object type must be passed. otherObjectTypeID must not be empty.

This cannot be used if a v1 attribute certificate is used.

Parameters:

digestedObjectType - The digest object type.

digestAlgorithm - The algorithm identifier for the hash.

otherObjectTypeID - The object type ID if digestedObjectType is otherObjectDigest.

objectDigest - The hash value.

Method Detail

getDigestedObjectType

public int getDigestedObjectType()

Returns the digest object type if an object digest info is used.

• 0 - publicKey - A hash of the public key of the holder must be passed.
• 1 - publicKeyCert - A hash of the public key certificate of the holder must be passed.
• 2 - otherObjectDigest - A hash of some other object type must be passed. otherObjectTypeID must not be empty.

Returns:

The digest object type or -1 if no object digest info is set.

getDigestAlgorithm

public AlgorithmIdentifier getDigestAlgorithm()

Returns algorithm identifier for the digest used if ObjectDigestInfo is present.

Returns:

digest AlgorithmIdentifier or null if ObjectDigestInfo is absent.

getObjectDigest

public byte[] getObjectDigest()

Returns the hash if an object digest info is used.

Returns:

The hash or null if ObjectDigestInfo is absent.

getOtherObjectTypeID

public ASN1ObjectIdentifier getOtherObjectTypeID()

Returns the digest algorithm ID if an object digest info is used.

Returns:

The digest algorithm ID or null if no object digest info is set.

getEntityNames

public X500Name[] getEntityNames()

Return any principal objects inside the attribute certificate holder entity names field.

Returns:

an array of Principal objects (usually X500Principal), null if no entity names field is set.

getIssuer

public X500Name[] getIssuer()

Return the principals associated with the issuer attached to this holder

Returns:

an array of principals, null if no BaseCertificateID is set.

getSerialNumber

public BigInteger getSerialNumber()

Return the serial number associated with the issuer attached to this holder.

Returns:

the certificate serial number, null if no BaseCertificateID is set.
