Hi, I'm trying to decrypt an ssl conversation using the ssl key.

This is working in the wireshark gui.
When I try to decrypt in tshark, this is also working, but I wan to decrypt it and save the result as a pcap file. This doesn't work.
When I use : tshark -o "ssl.desegment_ssl_records: TRUE" -o "ssl.desegment_ssl_application_data: TRUE" -o "ssl.keys_list: 10.135.56.22,443,http,/trace/test/test.pem" -t ad -r 443_test.pcap -w decrypted.pcap
the result is the same as the input-file.

Is there a way I can decrypt via cli to a pcap file?
I want to use the resulting pcap-file as input for tcpick, so I can save complete TCP sessions.

The short answer: Wireshark/tshark aren't capable of saving decrypted packets to a pcap file.

See message thread starting at http://www.wireshark.org/lists/wireshark-users/201105/msg00000.html for some (possibly) relevant information.

See especially: http://www.wireshark.org/lists/wireshark-users/201105/msg00002.html

A Google search may find further info.

Is there an other way to create seperate files for each communication session? I'm now using tcpick to seperate the tcp streams from each other (and save each stream in a file) but this doesn't support ssl. I rather use wireshark, but is this even possible?
