Implement HTTPS on Tomcat Server for Pega application

[saichinnu1852]

We have an Tomcat App server and we are running Pega application on top of it, we would like to implement HTTPS for our application. I have been provided with CA certificate to implement HTTPS.

Process: To achieve this I have created a key store and I have imported the CA certificate into it and changed some configurations in server.xml file. I have also given Key store path and key store password. After restarting the server, I was able to browse the URL with HTTPS, but it is throwing an error saying "this certificate is invalid". As per my understanding, it is taking the key store private key certificate instead of CA certificate which is incorrect. Can some please advise me how to solve this issue.

You might need to check your Apache settings for your CA Certificate.  And you might need to convert it as well.  Here is a good place to start with a lot of information on configuring HTTPS on Tomcat.

Also, a great resource that I use to combine and convert certifications can be found here.

Good Luck!

Implementing HTTPS on a Tomcat server for a Pega application requires a few key steps, especially when dealing with CA certificates and keystores. Here's a general outline of what you should check and configure to resolve the "this certificate is invalid" error. ### Steps to Implement HTTPS on Tomcat 1. **Generate a Keystore**: If you haven't already, generate a keystore. If you already have a keystore, make sure it contains your private key and the corresponding certificate chain. ```bash keytool -genkey -alias youralias -keyalg RSA -keystore yourkeystore.jks ``` 2. **Import the CA Certificate**: After generating a keystore and obtaining your CA certificate, you need to import it properly. ```bash keytool -import -alias cacert -file cacert.crt -keystore yourkeystore.jks ``` Make sure to import the entire certificate chain if you have intermediate certificates as well. 3. **Check the Keystore Content**: Verify the contents of your keystore to ensure that the private key and the certificates are correctly imported. ```bash keytool -list -v -keystore yourkeystore.jks ``` 4. **Update `server.xml`**: Ensure your `server.xml` file has the correct configuration for the `` for HTTPS. It should look something like this: ```xml ``` Ensure that the paths and passwords are correct. 5. **Verify Certificate Chain**: Ensure that the certificate chain is correct in your keystore. If you imported the CA certificate, it might need to be chained correctly with your server certificate. This means your server's public certificate should be imported along with any intermediate certificates. ```bash keytool -import -alias yourdomain -file yourdomain.crt -keystore yourkeystore.jks ``` Follow this with any intermediate certificates if necessary. 6. **Restart Tomcat**: After making these changes, restart Tomcat. 7. **Check Browser Errors**: If you still encounter "this certificate is invalid", check the following: - Ensure that the certificate matches the domain you are accessing. - Verify that the entire certificate chain is present in the keystore. - Use a tool like `openssl` or an online SSL checker to see if there are any issues with the certificate chain. ```bash openssl s_client -connect yourdomain:8443 -showcerts ``` ### Troubleshooting - **Certificate Trust**: If you’re testing in a non-production environment, make sure your browser trusts the CA certificate you imported. - **Hostname Verification**: Ensure that the CN (Common Name) in your certificate matches the hostname you are using to access the application. - **Logs**: Check Tomcat logs for any error messages that might provide more details about the SSL issue. ### Conclusion By following these steps, you should be able to implement HTTPS successfully on your Tomcat server for the Pega application. If you continue to have issues, consider re-checking each step or looking into specific error messages in the Tomcat logs.

It seems like the issue is with the certificate chain in your keystore. To fix it:

1. Ensure you’ve imported the CA certificate along with any intermediate certificates into the keystore.
2. Check that the alias used for the private key matches the alias in the keystore configuration.
3. Verify your server.xml configuration is correct and points to the proper keystore file.
4. Restart Tomcat after making changes.
