  +--net.rim.device.api.crypto.InitializationVectorFactory

public class InitializationVectorFactory
extends Object

Contains the functionality for a high level approach to creating InitializationVectors.

For more information on the cryptographic algorithms supported by this factory, see Crypto Algorithms.

Category:
Signed: This element is only accessible by signed clients. If you intend to use this element, please contact RIM to establish the necessary agreements that will allow you to have your COD files signed. Signing is only required for use on the device, development under the JDE can occur without signing the CODs.

Since:
JDE 3.6.0

getInstance

public static InitializationVector getInstance(String algorithm,
                                               byte[] data,
                                               int offset,
                                               int maxLength)
                                        throws NoSuchAlgorithmException
Constructs and returns a new InitializationVector object.

The default length is used if algorithm does not specify a block length.

Parameters:
algorithm - The name of the InitializationVector to construct, eg "DES", "TripleDES".
data - The iv data.
offset - The start, or initial position, of the iv data within the array.
maxLength - The maximum length, in bytes, of the data available to the iv. Not all of the data may be required depending on the algorithm.
Returns:
An InitializationVector object.
Throws:
NoSuchAlgorithmException - Thrown if the InitializationVector cannot be constructed or the specified algorithm is invalid.
Since:
JDE 4.0.2

                                        throws NoSuchAlgorithmException
Constructs and returns a new InitializationVector object.

A InitializationVector object is selected based on algorithm.

Parameters:
algorithm - The name of the InitializationVector to construct, eg "DES", "TripleDES".
data - The iv data.
offset - The start, or initial position, of the iv data within the array.
Returns:
A InitializationVector object.
Throws:
NoSuchAlgorithmException - Thrown if the InitializationVector cannot be constructed or the specified algorithm is invalid.
