# Configuration with a self-signed certificate

The following steps describe the configuration with an SSL self-signed certificate. If you already have a certificate, or a keystore that contains a certificate, you can skip this section and go directly to the next section on how to configure Qlik Talend Cloud Migration Toolkit with an existing keystore.

## About this task

The two main steps are:

* Creating a Java keystore containing a self-signed certificate.
* Setting Qlik Talend Cloud Migration Toolkit server with the SSL configuration.

Those steps can be automated using the following example scripts.

## Procedure

1. Open, in your browser, the README.html from the QTCMT installation folder.
2. Go to the section Configure QTCMT with a self-signed certificate.
3. Expand the section setup-qtcmt-https.bat (Click to reveal) on Windows or setup-qtcmt-https.sh (Click to reveal) on Linux or Mac and copy the content.
4. Create the script file (setup-qtcmt-https.bat or setup-qtcmt-https.sh) in the QTCMT installation folder.
5. Open the file with a text editor like Notepad++.
6. Paste the content from the step 3 and save the file.

## Results

The script creates a keystore based on some default parameters and generates a new start script to execute Qlik Talend Cloud Migration Toolkit configured with HTTPS.
