Install and Setup Burp Suite Proxy & Certificate with Java Application

This article demonstrates how to configure the Burp Suite certificate for Java applications.

Introduction

Java applications sometimes bypass global proxy settings, which means that setting up a proxy and importing the Burp Suite certificate may not be sufficient to intercept HTTPS traffic.

This article will guide you through setting up your Burp Suite proxy and certificate with a Java application to intercept HTTPS traffic effectively.

Environment

1. A freshly installed Windows 7 with Internet Explorer;
2. A Java application;
3. Firefox and Burp Suite Pro installed;
4. Burp Suite certificate imported into Firefox and IE.

Preparation

Install Java Environment

Navigate to the Java official website to download and install Java.

Restart Computer

Ensure that all configurations take effect by restarting your computer.

Setup Burp Suite Proxy & Certificate with Java Application

Import Burp Suite Certificate

Open CMD and navigate to the Java bin folder. Note that the version number “jre1.8.0_261” may vary.

cd C:\Program Files\Java\jre1.8.0_261\bin

Execute the following command to import the Burp Suite certificate into the Java KeyStore using KeyTool, a command-line utility that manages keys and certificates.

keytool.exe -import -trustcacerts -file C:\Users\IEUser\Downloads\1.der -alias BURPSUITE -keystore burp.jks

When prompted, provide a password for the KeyStore. I used “123456”. Remember this password as it will be required later.

To verify the certificate has been imported successfully, execute the following:

keytool -keystore burp.jks -list

You have now successfully imported the Burp Suite certificate into Java.

Setup Burp Suite Proxy

When launching your Java application, include the following parameters to ensure the application uses the specified KeyStore:

-Djavax.net.ssl.trustStore=C:\Program Files\Java\jre1.8.0_261\bin\burp.jks
-Djavax.net.ssl.trustStorePassword=123456

With these settings, you should be able to intercept HTTPS traffic using Burp Suite.
