Member Enumeration Documentation

◆ SignerType

enum ndn::security::SigningInfo::SignerType

Enumerator
SIGNER_TYPE_NULL	No signer is specified, use default setting or follow the trust schema.
SIGNER_TYPE_ID	Signer is an identity, use its default key and default certificate.
SIGNER_TYPE_KEY	Signer is a key, use its default certificate.
SIGNER_TYPE_CERT	Signer is a certificate, use it directly.
SIGNER_TYPE_SHA256	Use a SHA-256 digest only, no signer needs to be specified.
SIGNER_TYPE_HMAC	Signer is a HMAC key.

◆ SigningInfo() [1/4]

ndn::security::SigningInfo::SigningInfo	(	SignerType	signerType = `SIGNER_TYPE_NULL`,
		const Name &	signerName = `Name()`,
		const SignatureInfo &	signatureInfo = `SignatureInfo()`
	)

explicit

Constructor.

Parameters

signerType	The type of signer
signerName	The name of the signer; interpretation differs with the type of signer
signatureInfo	A semi-prepared SignatureInfo that contains all necessary information except SignatureType and KeyLocator. If SignatureType and/or KeyLocator is set, they will be overwritten by KeyChain::sign().

◆ SigningInfo() [4/4]

ndn::security::SigningInfo::SigningInfo ( const std::string & signingStr )

explicit

Construct SigningInfo from its string representation.

Parameters

signingStr The representative signing string for SigningInfo signing method

Syntax of the representative string is as follows:

default signing: "" (empty string)
sign with the default certificate of the default key of an identity: id:/<my-identity>
sign with the default certificate of a specific key: key:/<my-identity>/ksk-1
sign with a specific certificate: cert:/<my-identity>/KEY/ksk-1/ID-CERT/FD%01
sign with HMAC-SHA-256: hmac-sha256:<base64-encoded-key>
sign with SHA-256 (digest only): id:/localhost/identity/digest-sha256
