[Ndn-interest] How to verify an interest packet

[Junxiao Shi]

Hi Matteo

What's the error reason passed to onInterestValidationFailed function?

Is the certificate properly published? In other words, can you retrieve the certificate by expressing an Interest using ndnpeel?

Yours, Junxiao

Dear community,
I am having some problem in verifying an interest packet.
Specifically, the error is: Packet cannot pass any checkers.

A root authority signs the certificate of the sender of the interest

My file config is:
rule
{
   id "p rule"
   checker
   {
     type hierarchical
     sig-type rsa-sha256
   }
}
trust-anchor
{
   type file
   file-name /tmp/p/root.ndncert
}

So it is very simple.
The sender of the interest, signs the interest in this way:
Name producerId("/root/site2"); ///test/site2/user2
m_keyChain.signByIdentity(interest, producerId);

While the content producer verifies it so:
void onInterest(const InterestFilter& filter, const Interest& interest)
{
m_validator->validate(interest, bind(&Producer::sendData, this, _1),
                           bind(&Producer::onInterestValidationFailed,  
this, _1, _2));
   }

The interest sent has the key included in the name, I noticed:
/root/site1/%00%00%01W%9F8%C4%11/%5Dl%F4%D2%8F%C5%D1%D6/%165%1B%01%01%1C0%07.%08%04root%08%03KEY%08%05site2%08%11ksk-1475844947720%08%07ID-CERT/%17%FD%01%0  
[...]

Do you notice any error?
Yours,
Matteo
