Description

Discussed in https://github.com/tlsfuzzer/tlslite-ng/discussions/522

Originally posted by octaviandumitran June 28, 2024 Can you add functionality to generate a key log file? This should be something similar to what Python3.8+ does when SSLKEYLOGFILE is defined.

Alternatively, could you explain how I can generate the file myself? Presumably, I would need to call keyingMaterialExporter, but I do not know exactly how to serialize that.

Contributor guide

Research direction
Study the existing keyingMaterialExporter method in tlslite ng and the NSS Key Log format. Implement a handler for the SSLKEYLOGFILE environment variable to write key log entries during TLS handshake.
