Constructor Detail

ObjectDigestInfo

protected ObjectDigestInfo()

ObjectDigestInfo

public ObjectDigestInfo(int digestedObjectType,
                        java.lang.String otherObjectTypeID,
                        java.lang.String digestAlgorithm,
                        BIT_STRING objectDigest)

This constructor is used to construct an ObjectDigestInfo object out of the specified components.

Parameters:

digestedObjectType - can be one of the values: PUBLIC_KEY, PUBLIC_KEY_CERT or OTHER_OBJECT_TYPES

otherObjectTypeID - must contain the value of the ObjectID if the digestedObjectType is OTHER_OBJECT_TYPES

digestAlgorithm - must be the dotted form of the OID of the algorithm

objectDigest - is the bit string of the object digest value

ObjectDigestInfo

public ObjectDigestInfo(ObjectDigestInfo odi)

This constructor copies a given ObjectDigestInfo.

Parameters:

odi - - the ObjectDigestInfo to copy

Method Detail

getObjectType

public int getObjectType()

Returns Digested Object Type. See PUBLIC_KEY, PUBLIC_KEY_CERT and OTHER_OBJECT_TYPES.

setObjectType

public void setObjectType(int objectType)

Sets Digested Object Type. See PUBLIC_KEY, PUBLIC_KEY_CERT and OTHER_OBJECT_TYPES.

You have to set the type of the object, unless you did so by passing a correct value to the constructor.

getOtherObjectType

public java.lang.String getOtherObjectType()

Returns the OID of the digested object Type, if it is not a public key or PKC; in the latter case it is null.

setOtherObjectType

public void setOtherObjectType(java.lang.String oid)

Sets the OID of the digested object Type, if it is not a public key or PKC. Can be null.

getDigestAlgorithmID

public java.lang.String getDigestAlgorithmID()

Returns the OID of the digest algorithm in the dotted form.

setDigestAlgorithmID

public void setDigestAlgorithmID(java.lang.String oid)

Sets the OID of the digest algorithm in the dotted form.

getObjectDigest

public BIT_STRING getObjectDigest()

Returns the Bit String of the digest of the object.

setObjectDigest

public void setObjectDigest(BIT_STRING objectDigest)

Returns the Bit String of the digest of the object.

toASN1Object

public ASN1Object toASN1Object()
                        throws CodingException

This method returns the ASN1Object of this ObjectDigestInfo.

Returns:

SEQUENCE of object type, the digest algorithm identifier and the actual object digest; if object type is OTHER_OBJECT_TYPES, then the ObjectID of that object type is also added before the digest algorithm identifier

Throws:

CodingException

decode

public void decode(ASN1Object ao)
            throws CodingException

This method decodes a given ASN1Object and sets the contents from it. It must be a SEQUENCE of object type, digest algorithm identifier and the actual digest of the object; for OTHER_OBJECT_TYPES there must be the ObjectID of the object type before the digest algorithm identifier.

Parameters:

ao - - the ASN1Object to decode

Throws:

CodingException

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

toString

public java.lang.String toString(java.lang.String indent)

clone

public java.lang.Object clone()

Overrides:

clone in class java.lang.Object
