	)

protectedpure virtualinherited

Check the Data against policy and return the next validation step if necessary.

If there is no next validation step, that validation MUST have been done. i.e., either onValidated or onValidationFailed callback is invoked.

Parameters

data	The Data to check.
nSteps	The number of validation steps that have been done.
onValidated	If the Data is validated, this calls onValidated(data)
onValidationFailed	If validation fails, this calls onValidationFailed(data)
nextSteps	On return, contains the next validation step

Implemented in ndn::security::CommandInterestValidator, and ndn::security::ValidatorConfig.

	)

protectedpure virtualinherited

Check the Interest against validation policy and return the next validation step if necessary.

If there is no next validation step, that validation MUST have been done. i.e., either onValidated or onValidationFailed callback is invoked.

Parameters

interest	The Interest to check.
nSteps	The number of validation steps that have been done.
onValidated	If the Interest is validated, this calls onValidated(data)
onValidationFailed	If validation fails, this calls onValidationFailed(data)
nextSteps	On return, contains the next validation step

Implemented in ndn::security::CommandInterestValidator, and ndn::security::ValidatorConfig.

void ndn::security::Validator::onData	(	const Interest &	interest,

		const lp::Nack &	nack,
		int	nRemainingRetries,
		const OnFailure &	onFailure,
		const shared_ptr< ValidationRequest > &	validationRequest
	)

protectedvirtualinherited

trigger when interest retrieves a Nack.

Validator can decide how to handle a Nack, either call onFailure, or retry.

Parameters

interest	The interest that retrieves a Nack.
nack	The Nack that is retrieved.
nRemainingRetries	The number of retries left.
onFailure	Failure callback when there is no more retries remaining.
validationRequest	The validationRequest containing the context of the interest.

void ndn::security::Validator::onTimeout	(	const Interest &	interest,
		int	nRemainingRetries,
		const OnFailure &	onFailure,
		const shared_ptr< ValidationRequest > &	validationRequest
	)

protectedvirtualinherited

trigger when interest for certificate times out.

Validator can decide how to handle the timeout, either call onFailure, or retry.

Parameters

interest	The interest that times out.
nRemainingRetries	The number of retries left.
onFailure	Failure callback when there is no more retries remaining.
validationRequest	The validationRequest containing the context of the interest.

virtual shared_ptr<const Data> ndn::security::Validator::preCertificateValidation ( const Data & data )

inlineprotectedvirtualinherited

Hooks.

trigger before validating requested certificate.

The Data:

matches the interest in the validation-request.
may be certificate or a data encapsulating certificate.

This method returns a data (actually certificate) that is will be passed as Data into: Validator::validate(const Data& data, const OnDataValidated& onValidated, const OnDataValidationFailed& onValidationFailed, int nSteps);

Definition at line 296 of file validator.hpp.

void ndn::security::Validator::setDirectCertFetchEnabled ( bool isEnabled )

inherited

Enable or disable the direct certificate fetch feature.

When enabled, the validator will attempt to fetch the certificate that signs an Interest from the sender of that Interest, as identified by IncomingFaceId field, in addition to fetching from the infrastructure.

Prior to enabling this feature, the application must enable NextHopFaceId privilege on the face used by this validator.

Note: Current implementation can only fetch the Interest signer certificate from the Interest sender; the issuer certificate of that certificate is only fetched from the infrastructure.; Currently, this feature can only be used with ValidatorConfig.

Parameters

isEnabled Set true to enable the feature or false to disable.

void ndn::security::Validator::validate	(	const Data &	data,
		const OnDataValidated &	onValidated,
		const OnDataValidationFailed &	onValidationFailed
	)

inlineinherited

Validate Data and call either onValidated or onValidationFailed.

Parameters

data	The Data with the signature to check.
onValidated	If the Data is validated, this calls onValidated(data).
onValidationFailed	If validation fails, this calls onValidationFailed(data).

Definition at line 78 of file validator.hpp.
