Detailed Description

A Signature is an abstract base class providing methods to work with the signature information in a Data packet.

You must create an object of a subclass, for example Sha256WithRsaSignature.

Member Function Documentation

virtual ptr_lib::shared_ptr<Signature> ndn::Signature::clone ( ) const

pure virtual

Return a pointer to a new Signature which is a copy of this signature.

This is pure virtual, the subclass must implement it.

Implemented in ndn::Sha256WithEcdsaSignature, ndn::Sha256WithRsaSignature, and ndn::DigestSha256Signature.

virtual void ndn::Signature::get ( struct ndn_Signature & signatureStruct ) const

pure virtual

Set the signatureStruct to point to the values in this signature object, without copying any memory.

WARNING: The resulting pointers in signatureStruct are invalid after a further use of this object which could reallocate memory. This is pure virtual, the subclass must implement it.

Parameters

signatureStruct a C ndn_Signature struct where the name components array is already allocated.

Implemented in ndn::Sha256WithEcdsaSignature, ndn::DigestSha256Signature, and ndn::Sha256WithRsaSignature.

virtual uint64_t ndn::Signature::getChangeCount ( ) const

pure virtual

Get the change count, which is incremented each time this object (or a child object) is changed.
