◆ getKeyLocatorName()

Name ndn::security::getKeyLocatorName	(	const SignatureInfo &	sigInfo,

	)

Extract the KeyLocator name from a SignatureInfo element.

sigInfo must contain a KeyLocator of Name type. Otherwise, ValidationState::fail() is invoked on state with a ValidationError::INVALID_KEY_LOCATOR error code.

Legacy signed Interests must contain a (Data)SignatureInfo name component. In both cases, if any TLV parsing errors are encountered, ValidationState::fail() is invoked on state with a ValidationError::MALFORMED_SIGNATURE error code.

Precondition: state must contain a SignedInterestFormatTag to indicate whether the Interest is signed according to Packet Specification v0.3+ or a previous specification.
