# TLS Key Logging

Explain how to use TLS Key Logging with Proxyman to record TLS Session Keys. Useful for debugging with Wireshark

## 1. What's it?

Proxyman can capture TLS Key Logging and export as a txt file, so you can use it to decrypt HTTPS from Wireshark or [TCPViewer](https://tcpviewer.proxyman.com/) app

How to use it

1. Open Proxyman macOS
2. Make sure you setup the certificate on your mac correctly by following the Certificate Menu -> Install certificate for Mac -> Follow the guide to install it
3. Go to Tool menu -> TLS Key Logging
4. Enable and select the directory that the log will be saved

5. Done. As soon as Proxyman capture your traffic, Proxyman will extract the TLS Key and save to the log file
