Hi Bassem,

Did you call Face’s setCommandSigningInfo method before registerPrefix? NFD requires signed Interests to register new prefixes and setCommandSignInfo configures the library to use an identity. Otherwise, JNDN assumes you want to talk to NDNx.

I have a (python) setCommandSigningInfo example here: https://github.com/dibenede/ndn-tutorial-gec21/blob/master/solutions/hello_producer.py <https://github.com/dibenede/ndn-tutorial-gec21/blob/master/solutions/hello_producer.py> . The KeyChain is initialized in __init__().
