I'm sniffing a connection that uses ICEP (ZeroC ICE Protocol), and its packet bodies compressed using BZ2 (GNU BZip 2) algorithm.
I want to find out whether packets encrypted, or not. ICEP can use OpenSSL to encrypt the traffic.
It's a local network, and I use WireShark to analyze the traffic. The client is a .Net application on windows, and Server is a Python application on a Gnu/Linux machine. If they use any encryption, it is possibly the ADH (Anonymous Diffie-Hellman cipher) cipher.
I also tried to use the command
# openssl s_client, but it says:
3894:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:s23_clnt.c:583:
