Hi, I have installed 3.2.4 version of wireshark but in Edit-> Preference->Protocol I can't see the SSL protocol so I selected TLS. Now I can't see nstrace.sskeys in (pre) Master-Secret log filename. I am following the tutorial at: Decrypting SSL and TLS Somebody please guide me is this file necessary for "decrypting SSL and TLS Traffic using wireshark" Zulfi.
