Video walkthrough of setting up ZAP tool for client applications:

  1. Installation
  1. Download ZAP from here.
  2. Install and open ZAP        

  1. Installing certificate

Since all requests and responses are proxied by ZAP, the certificate verification will fail for sites using SSL (HTTPS) and the connection will be terminated. To prevent this from happening, ZAP generates an SSL certificate for each host, signed by its own Certificate Authority (CA) certificate. This CA certificate is generated the first time ZAP is run, and is stored locally. To use the ZAP Proxy with these websites, you will need to install ZAP’s CA certificate as a trusted root for your device.

  1. Windows Applications
  • Goto Tools>Options>Dynamic SSL Certificate. Click Generate and then click Save.
  • Save the certificate in the desired location. Make sure the file has a .cer extension
  • Follow the below steps to upload the saved certificate:
  1. Open the start menu, type certmgr.msc into the search box (For windows 7 and above) and then press Enter.‌ If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
  2. Right click on “Trust Root Certification Authorities” > All tasks> Import

  1. Follow the wizard. When prompted for a file, select the file which was saved earlier. Choose the default options and complete the wizard. If there is security popup, click Yes to trust the certificate.
  2. If done properly, the ZAP certificate will be added to “Trusted Root Certification Authorities”
