BURP SSL certificate

To use Burp Proxy most effectively with HTTPS websites, you will need to install Burp's CA certificate as a trusted root in your browser. If you have not already done so, configure your browser to use Burp as its proxy, and configure Burp to generate a CA-signed, per-host certificate (this is the default setting).
