This is an implementation of the SSLKEYLOGFILE facility, available in Firefox and
Chromium/Google Chrome, that is supported by Wireshark in order to decrypt SSL/TLS connections
even when you don't have the private key, or when using key exchange methods that will prevent
decryption even if you do (Such as Diffie-Hellman).
This is for the standard library ssl module, it won't work for other ssl modules.
- Note:
Python 3.8+ includes built-in support for generating an SSL key log file via
ssl.SSLContext.keylog_filename, and will also enable it when theSSLKEYLOGFILEenvironment variable is set when creating a context viassl.create_default_context.This package uses the same callback the built-in implementation is using, which will likely cause both implementations to trample each other, causing the other not to work, or other unintended consequences. As such, you should probably not enable both at the same time.
import os
import sslkeylog
sslkeylog.set_keylog(os.environ.get('SSLKEYLOGFILE')) # Or directly specify a path
# Do anything involving SSL (Using the built-in ssl module)Set the SSLKEYLOGFILE environment variable if you use it, and set "(Pre)-Master-Secret log
filename" in Wireshark's SSL protocol preferences to the resulting file.
