[Nfd-dev] Try NDNCERT (based on Interest-Data exchange) and get an NDN certificate today

[Junxiao Shi]

Hi Zhiyi

It seems that the deployed CA is not implementing /CA/_PROBE/INFO protocol
correctly.

NDNCERT protocol 0.2
<https://github.com/named-data/ndncert/wiki/NDNCERT-Protocol-0.2/6a0aab2e7ffe8fd6f68f04dccd27e84ed65b3e32>
section
2.3.1 says:

JSON format:


   - "name": assigned sub-namespace (appears when PROBE Interest carries
      Parameters).
      - "ca-config": ca configuration content (appears when PROBE Interest
      ends with CA/PROBE/INFO).

and gives an example:

Interest:
Name: /ndn/CA/_PROBE/INFO

Data:
Name: /ndn/CA/_PROBE/INFO
Content:
{
  "ca-config": {
    "ca-prefix": "/zhiyi-home/controller"
    "probe": "email"
    "certificate": "Bv0CJAcsCANuZG4IBXNpd..."
  }
}
Signature



According to the protocol, the /CA/_PROBE/INFO response should be a JSON
object that contains a key "ca-config".

However, the packet retrieved from the deployed CA is missing the
"ca-config" key, but incorrectly placed the config object at top level:

$ ndnpeek -p /ndn/edu/ucla/yufeng/CA/_PROBE/INFO
{
    "ca-prefix": "\/ndn\/edu\/ucla\/yufeng",
    "ca-info": "UCLA CA",
    "probe": "email",
    "certificate":
