#### Description Wireshark project allows embedding session encryption keys into PCAP files. So it allows parsing encrypted packets as it was unencrypted. [More info](https://blog.didierstevens.com/2021/01/11/decrypting-tls-streams-with-wiresh...) I prepared a change that allows export session encryption keys. Please review PR. If ok, then I add commits with DocBook info.
Kyys may be emeberd using command ``` editcap --inject-secrets tls,/var/lib/kamailio/session_keylog encrypted.pcap with_keys.pcapng ```
