      • createObject

        public long createObject​(AttributeVector template)
                  throws TokenException
        Create a new object on the token (or in the session). The application must provide a template that holds enough information to create a certain object. For instance, if the application wants to create a new DES key object it creates a new instance of the AttributesTemplate class to serve as a template. The application must set all attributes of this new object which are required for the creation of such an object on the token. Then it passes this DESSecretKey object to this method to create the object on the token. Example: AttributesTemplate desKeyTemplate = AttributesTemplate.newSecretKey(CKK_DES3); // the key type is set by the DESSecretKey's constructor, so you need not do it desKeyTemplate.value(myDesKeyValueAs8BytesLongByteArray) .token(true) .private(true); .encrypt(true); .decrypt(true); ... long theCreatedDESKeyObjectHandle = userSession.createObject(desKeyTemplate); Refer to the PKCS#11 standard to find out what attributes must be set for certain types of objects to create them on the token.
        Parameters:
        template - The template object that holds all values that the new object on the token should contain.
        Returns:
        A new PKCS#11 Object that serves holds all the (readable) attributes of the object on the token. In contrast to the templateObject, this object might have certain attributes set to token-dependent default-values.
        Throws:
        TokenException - If the creation of the new object fails. If it fails, the no new object was created on the token.

      • createECPrivateKeyObject

        public long createECPrivateKeyObject​(AttributeVector template,
                                     byte[] ecPoint)
                              throws TokenException
        Create EC private key object in the PKCS#11 device.
        Parameters:
        template - Template of the EC private key.
        ecPoint - The encoded EC-Point. May be null.
        Returns:
        object handle of the new EC private key.

                       AttributeVector template)
                throws TokenException
        Copy an existing object. The source object and a template object are given. Any value set in the template object will override the corresponding value from the source object, when the new object is created. See the PKCS#11 standard for details.
        Parameters:
        sourceObjectHandle - The source object of the copy operation.
        template - A template object whose attribute values are used for the new object; i.e. they have higher priority than the attribute values from the source object. May be null; in that case the new object is just a one-to-one copy of the sourceObject.
        Returns:
        The new object that is created by copying the source object and setting attributes to the values given by the template.
        Throws:
        TokenException - If copying the object fails for some reason.

      • setAttributeValues

        public void setAttributeValues​(long objectToUpdateHandle,
                               AttributeVector template)
                        throws TokenException
        Gets all present attributes of the given template object an writes them to the object to update on the token (or in the session). Both parameters may refer to the same Java object. This is possible, because this method only needs the object handle of the objectToUpdate, and gets the attributes to set from the template. This means, an application can get the object using createObject of findObject, then modify attributes of this Java object and then call this method passing this object as both parameters. This will update the object on the token to the values as modified in the Java object.
        Parameters:
        objectToUpdateHandle - The attributes of this object get updated.
        template - This methods gets all present attributes of this template object and set this attributes at the objectToUpdate.
        Throws:
        TokenException - If updating the attributes fails. All or no attributes are updated.

        Parameters:
        objectHandle - The object handle that should be destroyed.
        Throws:
        TokenException - If the object could not be destroyed.
