Field Detail

subprime_

protected ByteArrayAttribute subprime_
The subprime (q) of this DH key.

subprimeBits_

protected LongAttribute subprimeBits_
The length of the subprime value in bits.
Constructor Detail

X942DHParams

public X942DHParams()
Default Constructor.

X942DHParams

protected X942DHParams(Session session,
                       long objectHandle)
                throws TokenException
Called by getInstance to create an instance of a PKCS#11 DH 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 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 DH 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.

putAttributesInTable

protected static void putAttributesInTable(X942DHParams 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.

allocateAttributes

protected void allocateAttributes()
Allocates the attribute objects for this class and adds them to the attribute table.
Overrides:
allocateAttributes in class DHParams

clone

public java.lang.Object clone()
Create a (deep) clone of this object.
Overrides:
clone in class DHParams
Returns:
A clone of this object.

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 DHParams
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 DH key.
Overrides:
getPrime in class DHParams
Returns:
The prime attribute.

getBase

public ByteArrayAttribute getBase()
Gets the base attribute of this DH key.
Overrides:
getBase in class DHParams
Returns:
The base attribute.

getSubprime

public ByteArrayAttribute getSubprime()
Gets the subprime attribute of this DH key.
Returns:
The subprime attribute.

getPrimeBits

public LongAttribute getPrimeBits()
Gets the value length of the prime (in bits).
Overrides:
getPrimeBits in class DHParams
Returns:
The prime bits attribute.

getSubprimeBits

public LongAttribute getSubprimeBits()
Gets the value length of the subprime (in bits).
Returns:
The subprime bits attribute.

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 DHParams
Returns:
A string presentation of this object for debugging output.
