hi,

I am currently working with security in IBRDTN. I am using CORE (common open research emulator) platform, on which there two connected with a wired interface, nodes which run ibrdtn version 1.0.1 with the command dtnd -d 80 -c <path to ibrdtn.conf>. Both the nodes run same configuration file which is attached herewith.

1. Both the nodes are able to dtnping each other.
   
2. I use dtnsend --encrypt command with the specified file to the other node.
3. On wireshark capture of the whole setup there are no encrypted packets being exchanged, plain texts are observed in exchange between the nodes.
   
4. deamon debug logs have been listed here.
5. Additionally i also generated keys for both the nodes in etc/ibrdtn/bpsec folder the public/private key for both the nodes along with the default-bab-key.mac and; local.crt and local.key in /etc/ibrdtn/tls/
   

Deamon log on the transmitting node dtn://n1/
