void ndn::security::v2::CertificateStorage::loadAnchor	(	const std::string &	groupId,
		Certificate &&	cert
	)

protected

load static trust anchor.

Static trust anchors are permanently associated with the validator and never expire.

Parameters

groupId	Certificate group id.
cert	Certificate to load as a trust anchor.

		const std::string &	certfilePath,
		time::nanoseconds	refreshPeriod,
		bool	isDir = `false`
	)

protected

load dynamic trust anchors.

Dynamic trust anchors are associated with the validator for as long as the underlying trust anchor file (set of files) exist(s).

Parameters

groupId	Certificate group id, must not be empty.
certfilePath	Specifies the path to load the trust anchors.
refreshPeriod	Refresh period for the trust anchors, must be positive.
isDir	Tells whether the path is a directory or a single file.

void ndn::security::v2::CertificateStorage::resetAnchors ( )
