Use OpenSSL to decrypt TLS session from PCAP files

[Oren Shpigel <orens@xxxxxxxxxxxxxxxxxx>]

Hi, 

I generated a PCAP file with TLS session, and I have the matching private key used by my HTTPS server.
The TLS session is not using DH for key exchange, so it should be possible to decrypt.
I know OpenSSL can be used to connect to a socket to "actively" handle the TLS session, but is there a way to "passively" decode and decrypt a session?
How can I "feed" the packets (both directions) into the OpenSSL library?

Thanks!
