Just added a new feature to vibe-stream for anyone doing TLS debugging with wireshark.

There is a feature supported on cURL and most browsers known as SSLKEYLOGFILE

A quick tutorial on how to use it in cURL is here.

For the updated vibe-stream (1.3.0), you can enable the feature (that it uses the environment variable to set up a key log file) by enabling version VibeKeylogFromEnvironment.

You can also set up key logging by assigning your own function to the new field (on OpenSSLContext) called keylogCallback. This may not be in docs yet, I'm not sure how they update on vibed.org.

Note that this feature is only available with libssl version 1.1.1 or higher. It does not work on other libraries or prior versions (though 1.1.1 is quite old).

Enjoy!
