Let's Encrypt Windows Tomcat - Shell-Bash

If you are a Windows Tomcat developer, you may want to secure your website with SSL certification. Let's Encrypt provides a free and automated way to obtain SSL certificates for your website. In this tutorial, we will show you how to use Let's Encrypt on Windows Tomcat using the Shell/Bash command.

Prerequisites

• A Windows operating system
• Tomcat installed on your system
• The Shell/Bash command installed on your system
• Your website domain name

Step 1: Downloading Win-ACME

Win-ACME is a command-line tool used to automate the process of obtaining and installing SSL certificates from Let's Encrypt.

1. Download the Win-ACME zip file from the official website https://www.win-acme.com/
2. Extract the zip file to a directory on your system

Step 2: Start the Tomcat Server

Start the Tomcat server by running the following command in the Shell/Bash console:

cd [tomcat_directory]\bin
startup.bat

Step 3: Generate the SSL Certificate

1. Open the Shell/Bash console

2. Navigate to the Win-ACME directory by running the following command:

   cd [win-acme_directory]
   

3. Run the following command to generate the SSL certificate:

   .\wacs.exe --target manual --host [your_domain_name] --validation filesystem --webroot [tomcat_directory]/webapps/ROOT/.well-known/acme-challenge --store pemfiles --pemfilespath [tomcat_directory]\conf\.keystore --certificatestore My
   

4. Follow the instructions provided by the tool to complete the SSL certificate generation process

Step 4: Configure Tomcat for SSL

1. Navigate to the conf directory in your Tomcat installation folder

2. Open the server.xml file

3. Uncomment the following lines:

   <Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true"
                  maxThreads="150" scheme="https" secure="true"
                  clientAuth="false" sslProtocol="TLS"
                  keystoreFile="[tomcat_directory]\conf\.keystore"
                  keystorePass="[your_keystore_password]" />
   

   Make sure to replace [tomcat_directory] and [your_keystore_password] with your actual Tomcat directory and keystore password.

4. Save and close the file

Step 5: Restart Tomcat Server

Restart the Tomcat server by running the following command in the Shell/Bash console:

cd [tomcat_directory]\bin
shutdown.bat

cd [tomcat_directory]\bin
startup.bat

Congratulations! You have now successfully set up Let's Encrypt on Windows Tomcat using Shel/Bash command.
