![]() Generate the certificate with the following command: Again, using openssl we'll generate the certificate, in this case I'm using a sha256 Hash and 3650 days (10 years) for its validity.Generate the key with the following command: We'll use openssl to generate the key, in this case I'm using a key size of 3072 bits.I'll explain how to generate your own self-signed* TLS CA Certificate and install it on you Android device: Generate a self-signed TLS CA Certificate In order to see the traffic in plaintext we'll need our proxy to seat in the middle of the communication between the server and the app and to serve a valid TLS Certificate to the app. Here is where the Man-in-the-Middle aka MitM approach comes handy. Now, you can turn on Intercept mode in Burp Suite and capture the app’s network traffic for analysis.One of the best trends these days is the shift to encrypted Internet traffic, aka Transport Layer Security or TLS, and mobile apps are not the exception, often when testing a mobile app we need/want to see the data being sent from and received on our mobile devices but since most of the apps are using TLS on their network requests we cannot just proxy the traffic and understand the communication between the app and its server. Now, restart the Android emulator to apply the changes.Ĭongratulations! You have successfully installed the Burp Suite certificate in the Android emulator. 0 Final: Restart the Android Emulator (Optional) Next, change the permission of the certificate: $ chmod 644 /system/etc/security/cacerts/. To ensure the certificate is in the correct location, remount the emulator as root using the following commands: $ adb root $ adb remount $ adb shell # mv /sdcard/.0 /system/etc/security/cacerts/ The command to push the certificate is: $ adb push. If you’re on a Mac, you can watch a video on how to install ADB on Mac. Use ADB tools to copy the certificate file to the Android emulator. Step 6: Copy the Certificate to the Emulator ![]() Make sure your Wi-Fi is connected and configure the proxy settings as follows: 0 Step 5: Set up Proxy on EmulatorĪfter launching the Android emulator, change the proxy settings by opening the “Settings” and navigating to the “Proxy” section. Now, rename the “burp.pem” file accordingly: mv burp.pem. Output the hash with “subject_hash_old” to rename the PEM file: openssl x509 -inform PEM -subject_hash_old -in burp.pem | head -1 Use OpenSSL to convert the “r” certificate to PEM format using the following command: openssl x509 -inform DER -in r -out burp.pem Save the certificate as “r” on your machine. Still in the “Proxy listeners” section, click on “Import / Export CA certificate” and export the certificate in DER format. Here, add a new listener with the following configurations: Port 8080, Ip 192.168.1.2 Step 3: Export Burp Suite Certificate Open “Options” and go to the “Proxy listeners” section. Launch Burp Suite and navigate to the “Proxy” tab. Step 2: Configure Burp Suite Proxy Listener Once installed, run the Android emulator of your choice. If you’re working with an Android emulator and want to capture and analyze its network traffic using Burp Suite, follow these steps to install the Burp Suite certificate in the emulator: Step 1: Install Android Emulatorĭownload and install any Anroid emulator. Burp Suite is a powerful tool for web application security testing and analysis.
