I'm on Windows 7 and have tried many permutations to no success.Some background: Wireshark supports decryption of SSL sessions when the master secret can be calculated (which can be derived from a pre-master secret). Tshark: Can't load private key from sysssl.log: can't import pem data: The requested data were not available. Tshark.exe -n -o 'tls.desegment_ssl_records: TRUE' -o 'tls.desegment_ssl_application_data: TRUE' -o 'tls.keys_list:,443,http,sysssl.log' -o 'tls.debug_file:SSL-Decrypt.log' -w 'RAW.capture' -b duration:10 -a duration:10 -q -Q -f 'tcp port 443' -T fields -e data.data I used TSHARK to try and decrypt the data with the following command: I configured Wireshark,TLS(not SSL) to use that file as the '(Pre)-Master-Secret log filename'

I closed the browser and stopped the trace. I've configured the environment SSLKEYLOGFILE variable which logs to disk just fine.Ĭlosed all applications, cleared the file, oped the desired IIS website using SSL and can see the enctyped application data. I have Wireshark 3.4.0 and am using TSHARK also.īasically, I am trying to get JSON text log data from the server-to-client response stream and write each packet to disk as text.

Wireshark decrypt tls with private key
