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

All Implemented Interfaces:

SignatureVerifier

public final class NullSignatureVerifier

extends Object

implements SignatureVerifier

The NullSignatureVerifier class implements a trivial (ie no) verification 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.

NullSignatureSigner

Constructor Summary

	NullSignatureVerifier() Creates a NullSignatureVerifier object.
	NullSignatureVerifier(boolean verify) Creates a NullSignatureVerifier object.

Method Summary

	String	getAlgorithm() Returns the name of the signing algorithm used, ie "Null".
	void	update(byte[] data) Adds additional message data to the signature.
	void	update(byte[] data, int offset, int length) Adds additional message data to the signature.
	void	update(int data) Adds additional message data to the signature.
	boolean	verify() Returns true or false depending on which constructor was invoked.

NullSignatureVerifier

public NullSignatureVerifier(boolean verify)

Creates a NullSignatureVerifier object.

This constructor allows the application to set the return value that they would like to see from the verify() method. The value passed into this constructor will be returned in the verify() method.

Parameters:

verify - the boolean that will be returned in the verify() method.
