Constructor Detail

DSAPrivateKey

public DSAPrivateKey()

Default Constructor.

DSAPrivateKey

protected DSAPrivateKey(Session session,
                        long objectHandle)
                 throws TokenException

Called by getInstance to create an instance of a PKCS#11 DSA private key.

Parameters:

session - The session to use for reading attributes. This session must have the appropriate rights; i.e. it must be a user-session, if it is a private object.

objectHandle - The object handle as given from the PKCS#111 module.

Throws:

TokenException - If getting the attributes failed.

Preconditions:

(session != null)

Method Detail

getInstance

public static Object getInstance(Session session,
                                 long objectHandle)
                          throws TokenException

The getInstance method of the PrivateKey class uses this method to create an instance of a PKCS#11 DSA private key.

Parameters:

session - The session to use for reading attributes. This session must have the appropriate rights; i.e. it must be a user-session, if it is a private object.

objectHandle - The object handle as given from the PKCS#111 module.

Returns:

The object representing the PKCS#11 object. The returned object can be casted to the according sub-class.

Throws:

TokenException - If getting the attributes failed.

Postconditions:

(result != null)

Preconditions:

(session != null)

putAttributesInTable

protected static void putAttributesInTable(DSAPrivateKey object)

Put all attributes of the given object into the attributes table of this object. This method is only static to be able to access invoke the implementation of this method for each class separately (see use in clone()).

Parameters:

object - The object to handle.

Preconditions:

(object != null)

allocateAttributes

protected void allocateAttributes()

Allocates the attribute objects for this class and adds them to the attribute table.

Overrides:

allocateAttributes in class PrivateKey

clone

public java.lang.Object clone()

Create a (deep) clone of this object.

Overrides:

clone in class PrivateKey

Returns:

A clone of this object.

Postconditions:

(result != null) and (result instanceof DSAPrivateKey) and (result.equals(this))

equals

public boolean equals(java.lang.Object otherObject)

Compares all member variables of this object with the other object. Returns only true, if all are equal in both objects.

Overrides:

equals in class PrivateKey

Parameters:

otherObject - The other object to compare to.

Returns:

True, if other is an instance of this class and all member variables of both objects are equal. False, otherwise.

getPrime

public ByteArrayAttribute getPrime()

Gets the prime attribute of this DSA key.

Returns:

The prime attribute.

Postconditions:

(result != null)

getSubprime

public ByteArrayAttribute getSubprime()

Gets the subprime attribute of this DSA key.

Returns:

The subprime attribute.

Postconditions:

(result != null)

getBase

public ByteArrayAttribute getBase()

Gets the base attribute of this DSA key.

Returns:

The base attribute.

Postconditions:

(result != null)

getValue

public ByteArrayAttribute getValue()

Gets the value attribute of this DSA key.

Returns:

The value attribute.

Postconditions:

(result != null)

toString

public java.lang.String toString()

This method returns a string representation of the current object. The output is only for debugging purposes and should not be used for other purposes.

Overrides:

toString in class PrivateKey

Returns:

A string presentation of this object for debugging output.

Postconditions:

(result != null)
