org.restlet.ext.crypto.internal.HttpDigestVerifier

All Implemented Interfaces:

Verifier

public class HttpDigestVerifier
extends DigestVerifier<LocalVerifier>

Verifier for the HTTP DIGEST authentication scheme. Note that the "A1" hash specified in RFC 2617 is available via the DigestVerifier.getWrappedSecretDigest(String) method.

Method Summary

Modifier and Type	Method and Description
protected char[]	digest(String identifier, char[] secret, String algorithm) If the algorithm is Digest.ALGORITHM_HTTP_DIGEST, then is retrieves the realm for getDigestAuthenticator() to compute the digest, otherwise, it keeps the default behavior.
DigestAuthenticator	getDigestAuthenticator() Returns the associated digest authenticator.
void	setDigestAuthenticator(DigestAuthenticator digestAuthenticator) Sets the associated digest authenticator.
int	verify(Request request, Response response) Verifies that the proposed secret is correct for the specified request.

Constructor Detail

HttpDigestVerifier

public HttpDigestVerifier(DigestAuthenticator digestAuthenticator,
                          LocalVerifier wrappedVerifier,
                          String wrappedAlgorithm)

Constructor.

Parameters:

digestAuthenticator - The associated digest authenticator.

wrappedAlgorithm - The digest algorithm of secrets provided by the wrapped verifier.

wrappedVerifier - The wrapped secret verifier.

Method Detail

digest

protected char[] digest(String identifier,
                        char[] secret,
                        String algorithm)

If the algorithm is Digest.ALGORITHM_HTTP_DIGEST, then is retrieves the realm for getDigestAuthenticator() to compute the digest, otherwise, it keeps the default behavior.

Overrides:

digest in class DigestVerifier<LocalVerifier>

Parameters:

identifier - The user identifier.

secret - The regular secret to digest.

algorithm - The digest algorithm to use.

Returns:

The digested secret.

Digest

getDigestAuthenticator

public DigestAuthenticator getDigestAuthenticator()

Returns the associated digest authenticator.

Returns:

The associated digest authenticator.

setDigestAuthenticator

public void setDigestAuthenticator(DigestAuthenticator digestAuthenticator)

Sets the associated digest authenticator.

Parameters:

digestAuthenticator - The associated digest authenticator.

verify

public int verify(Request request,
                  Response response)

Description copied from class: SecretVerifier

Verifies that the proposed secret is correct for the specified request. By default, it compares the inputSecret of the request's authentication response with the one obtain by the ChallengeResponse.getSecret() method and sets the User instance of the request's ClientInfo if successful.

Specified by:

verify in interface Verifier

Overrides:

verify in class SecretVerifier

Parameters:

request - The request to inspect.

response - The response to inspect.

Returns:

Result of the verification based on the RESULT_* constants.
