java.lang.Cloneable

public class ChallengeResponse
extends AbstractResponse

Object used to represent a challenge sent to a user asking for proof of their identity. The challenge includes a nonce (a random unpredictable set of bytes) as well as a digest of the request that is being challenged (so that the user can verify that they are only authorizing a specific operation).

Constructor Detail

ChallengeResponse

public ChallengeResponse(int opCode,
                         byte[] nonce)

Construct a challenge to the specified request. This constructor is used on the client side, when decoding messages.

ChallengeResponse

public ChallengeResponse(AbstractRequest req)
                  throws HandleException

Construct a challenge to the specified request. This constructor is used on the server side.

Throws:

HandleException

ChallengeResponse

public ChallengeResponse(AbstractRequest req,
                         boolean compatibility)
                  throws HandleException

Construct a challenge to the specified request. The compatibility parameter should be set to true when this challenge response is being created artificially to check a secret key.

Throws:

HandleException

Method Detail

initializeRandom

public static final void initializeRandom()

initializeRandom

public static final void initializeRandom(byte[] seed)

generateNonce

public static byte[] generateNonce()

Generate a nonce.
