Hello everyone,
I first want to analyze the frames in order to find the request on a site. When I analyze the frames I see that the protocol used is TLSv1.3. I created an environment variable to store the keys then put the file containing the keys in the wireshark preferences. But I still can't decode the frames. My goal is to find the arguments of the request in decrypted form
And the SSLKEYLOGFILE environment needs to be set for the TLS client (browser) or TLS server (web-service).
When I delete the contents of this file, launch my browser and make a request to a website, the key file does not fill up. If I open discord there the file fills up. But i want a key for website
My final goal would be to first retrieve the contents of a Get method with wireshark
When I delete the contents of this file, launch my browser and make a request to a website, the key file does not fill up.
So the SSLKEYLOGFILE is not picked up by your browser. As the procedure describes; "1. Close the browser completely (check your task manager just to be sure).", thus including any background processes before restarting it with the variable set.
when I close Chrome and open the task manager I no longer see the Chrome application. and I don't see any chrome processes either. When I restart Chrome nothing is written in the key file it remains blank.
If I restart my PC, and I launch Chrome, I will definitely have the key to decrypt the request made on Chrome?
To launch Chrome do:
On Windows on a command prompt:
set SSLKEYLOGFILE=%CD%\keylogfile.txt
"%ProgramFiles%\Google\Chrome\Application\chrome.exe"On Linux:
SSLKEYLOGFILE=$PWD/keylogfile.txt chrome &On MacOS:
export SSLKEYLOGFILE=$PWD/keylogfile.txt
open -a chromeI have succeeded in fill the key file by temporarily uninstalling my antivirus.
Then I can see the HTTP frames in wireshark. But in none of these frames I can find the query request which is entered in the browser
The procedure is described here: https://wiki.wireshark.org/TLS#using-...
Make sure your capture contains the TLS handshake, otherwise the decryption will fail.
And the SSLKEYLOGFILE environment needs to be set for the TLS client (browser) or TLS server (web-service).
SSLKEYLOGFILE does not work on libraries that do not support it, like Windows Secure Channel (Schannel).
