Field Detail

value

protected ByteArrayAttribute value

The value attribute of this secret key.

valueLen

protected LongAttribute valueLen

The length of this secret key in bytes.

Constructor Detail

ValuedSecretKey

public ValuedSecretKey(long keyType)

Default Constructor.

Parameters:

keyType - The type of the key.

ValuedSecretKey

protected ValuedSecretKey(Session session,
                          long objectHandle,
                          long keyType)
                   throws TokenException

Called by getInstance to create an instance of a PKCS#11 secret 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.

keyType - The type of the key.

Throws:

TokenException - If getting the attributes failed.

Method Detail

getInstance

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

The getInstance method of the SecretKey class uses this method to create an instance of a PKCS#11 AES secret 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.

keyType - The type of the key.

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(ValuedSecretKey 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 SecretKey

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 SecretKey

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.

getValue

public ByteArrayAttribute getValue()

Gets the value attribute of this AES key.

Returns:

The value attribute.

getValueLen

public LongAttribute getValueLen()

Gets the value length attribute of this AES key (in bytes).

Returns:

The value attribute.

readAttributes

public void readAttributes(Session session)
                    throws TokenException

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

Overrides:

readAttributes in class SecretKey

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 SecretKey

Returns:

A string presentation of this object for debugging output.
