Detailed Description

A SelfVerifyPolicyManager implements a PolicyManager to use the public key DER in the data packet's KeyLocator (if available) or look in the IdentityStorage for the public key with the name in the KeyLocator (if available) and use it to verify the data packet, without searching a certificate chain.

If the public key can't be found, the verification fails.

Constructor & Destructor Documentation

ndn::SelfVerifyPolicyManager::SelfVerifyPolicyManager ( IdentityStorage * identityStorage = 0 )

inline

Create a new SelfVerifyPolicyManager which will look up the public key in the given identityStorage.

Parameters

identityStorage (optional) The IdentityStorage for looking up the public key. This points to an object which must remain valid during the life of this SelfVerifyPolicyManager. If omitted, then don't look for a public key with the name in the KeyLocator and rely on the KeyLocator having the full public key DER.

Member Function Documentation

bool ndn::SelfVerifyPolicyManager::checkSigningPolicy	(	const Name &	dataName,
		const Name &	certificateName
	)

virtual

Override to always indicate that the signing certificate name and data name satisfy the signing policy.

Parameters

dataName	The name of data to be signed.
certificateName	The name of signing certificate.

Returns: true to indicate that the signing certificate can be used to sign the data.

Implements ndn::PolicyManager.

ptr_lib::shared_ptr< ValidationRequest > ndn::SelfVerifyPolicyManager::checkVerificationPolicy	(	const ptr_lib::shared_ptr< Data > &	data,
		int	stepCount,
		const OnVerified &	onVerified,
		const OnVerifyFailed &	onVerifyFailed
	)

virtual

Use the public key DER in the data packet's KeyLocator (if available) or look in the IdentityStorage for the public key with the name in the KeyLocator (if available) and use it to verify the data packet.

If the public key can't be found, call onVerifyFailed.

Parameters

data	The Data object with the signature to check.
stepCount	The number of verification steps that have been done, used to track the verification progress. (stepCount is ignored.)
onVerified	If the signature is verified, this calls onVerified(data).
onVerifyFailed	If the signature check fails or can't find the public key, this calls onVerifyFailed(data).

Returns: null for no further step for looking up a certificate chain.

Implements ndn::PolicyManager.

ptr_lib::shared_ptr< ValidationRequest > ndn::SelfVerifyPolicyManager::checkVerificationPolicy	(	const ptr_lib::shared_ptr< Interest > &	interest,
		int	stepCount,
		const OnVerifiedInterest &	onVerified,
		const OnVerifyInterestFailed &	onVerifyFailed,
		WireFormat &	wireFormat
	)

virtual

Use wireFormat.decodeSignatureInfoAndValue to decode the last two name components of the signed interest.

Use the public key DER in the signed interest SignatureInfo's KeyLocator (if available) or look in the IdentityStorage for the public key with the name in the KeyLocator (if available) and use it to verify the interest. If the public key can't be found, call onVerifyFailed.

Parameters

interest	The interest with the signature to check.
stepCount	The number of verification steps that have been done, used to track the verification progress. (stepCount is ignored.)
onVerified	If the signature is verified, this calls onVerified(interest).
onVerifyFailed	If the signature check fails or can't find the public key, this calls onVerifyFailed(interest).
