Constructor Detail

DSAParams

public DSAParams()

Default Constructor.

DSAParams

protected DSAParams(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.

Method Detail

getInstance

public static PKCS11Object getInstance(Session session,
                                       long objectHandle)
                                throws TokenException

The getInstance method of the PrivateKey class uses this method to create an instance of PKCS#11 DSA domain parameters.

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.

putAttributesInTable

protected static void putAttributesInTable(DSAParams 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.

Parameters:

object - The object to handle.

allocateAttributes

protected void allocateAttributes()

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

Overrides:

allocateAttributes in class DomainParameters

equals

public boolean equals(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 DomainParameters

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.

getSubprime

public ByteArrayAttribute getSubprime()

Gets the subprime attribute of this DSA key.

Returns:

The subprime attribute.

getBase

public ByteArrayAttribute getBase()

Gets the base attribute of this DSA key.

Returns:

The base attribute.

getPrimeBits

public LongAttribute getPrimeBits()

Gets the bit length of the prime value.

Returns:

The bit length of the prime value.

readAttributes

public void readAttributes(Session session)
                    throws TokenException

Read the values of the attributes of this object from the token.

Overrides:

readAttributes in class DomainParameters

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.

Throws:

TokenException - If getting the attributes failed.

toString

public String toString()

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 DomainParameters

Returns:

A string presentation of this object for debugging output.
