Install Charles Root Certificate in Windows 10

Charles can be used as HTTPS proxy so you can view https/SSL network traffic between your browser and web server. When SSL proxying is enabled in Charles, you will see a warning in your browser, or other application, indicating that the root authority is not trusted. This is because Charles generates its own certificates for sites, which it signs using a Charles Root Certificate. Charles receives the server’s certificate, while your browser receives Charles’s certificate. This certificate won’t be trusted by your browsers or applications. To fix this issue you have to put the Charles Root Certificate in your list of trusted root certificates on your computer.
