What is a Root Certificate Authority (CA) certificate?
A certificate is required to authenticate HTTPS connections, which are established when the browser connects to the webserver. JMeter creates it for the purpose of intercepting SSL traffic and recording actions. This certificate must be installed on your mobile device in order to record actions via mobile. It is necessary to install the JMeter protected CA certificate in the browser before recording any secured web application with JMeter.
The HTTP(S) Test Script Recorder in JMeter can be used to record the protected online application. Certificates are used to authenticate the connection between the browser and the web server in secured (HTTPS) communications. The server presents the certificate to the browser when connecting through HTTPS. The browser verifies that the server certificate is signed by a Certificate Authority (CA) that is related to one of the browser's built-in root CAs. To intercept the HTTPS connection from the browser, JMeter must utilise its own certificate to enable encrypted connections. JMeter must effectively impersonate the target server.
