Class NullSignatureSigner

java.lang.Object
  |
  +--net.rim.device.api.crypto.NullSignatureSigner

All Implemented Interfaces:

SignatureSigner

public final class NullSignatureSigner

extends Object

implements SignatureSigner

The NullSignatureSigner class implements a trivial (ie no) signing algorithm. The methods in this class do not perform any operations on the data.

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

NullSignatureVerifier

Constructor Summary

NullSignatureSigner() Constructs a NullSignatureSigner object.

Method Summary

	String	getAlgorithm() Returns the name of the signing algorithm used, ie "Null".
	String	getDigestAlgorithm() Returns the name of the digest algorithm used, ie "Null".
	void	reset()
	void	update(byte[] data)
	void	update(byte[] data, int offset, int length)
	void	update(int data)
