Member Function Documentation

makeCommandInterest()

Interest ndn::security::InterestSigner::makeCommandInterest	(	Name	name,
		const SigningInfo &	params = SigningInfo()
	)

Creates and signs a command Interest.

Deprecated:

Use the new signed Interest format instead of command Interests.

These can be created with makeSignedInterest.

This generates a nonce and timestamp for the command Interest.

Definition at line 63 of file interest-signer.cpp.

makeSignedInterest()

void ndn::security::InterestSigner::makeSignedInterest	(	Interest &	interest,
		SigningInfo	params = SigningInfo(),
		uint32_t	signingFlags = WantNonce | WantTime
	)

Signs an Interest (following Packet Specification v0.3 or newer)

Parameters

interest	Interest to sign
params	SigningInfo that provides parameters on how to sign the Interest.
signingFlags	Indicates which elements to include in the signature. At least one element must be specified for inclusion.

Exceptions

std::invalid_argument

No signature elements were specified for inclusion.
