Still do not like that ChatGPT does not want to provide sources to the answers.
I provided a query to a _somewhat_ common question with Java apps and TLS:
Query:
> identify root cause of this Java exception: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
Answer:
> The exception you're encountering, PKIX path building failed, typically indicates an issue with SSL/TLS certificate validation. Specifically, the error unable to find valid certification path to requested target suggests that the Java application cannot find a trusted certificate for the server it is trying to connect to. Here are the common root causes and solutions:
Missing Certificate in Truststore:
The server's SSL certificate (or the certificate of its issuing authority) is not present in the Java truststore.
Solution: Import the server's certificate into the Java truststore using the keytool command. You can obtain the certificate by using a browser or tools like openssl.
Self-Signed Certificate:
If the server is using a self-signed certificate, it won't be trusted by default.
Solution: Again, import the self-signed certificate into the Java truststore.
Incorrect Truststore Configuration:
The application might be pointing to an incorrect truststore or not configured to use one at all.
Solution: Ensure the application is configured to use the correct truststore and that the path is correctly set.
Expired Certificate:
The certificate used by the server might be expired.
Solution: Check the server's certificate validity and renew it if necessary.
Intermediate Certificates Missing:
If the server's certificate chain is incomplete (i.e., missing intermediate certificates), it can lead to this error.
Solution: Ensure that the complete certificate chain is presented by the server or manually import any missing intermediate certificates.
Network Issues:
There may be issues with the network or firewalls blocking access to the certificate validation services.
Solution: Check network configurations and ensure proper access.
To troubleshoot further, you can enable Java SSL debugging by adding the following JVM argument:
bash
Copy code
-Djavax.net.debug=ssl
This will provide more detailed output regarding the SSL handshake and help identify the specific issue.
It’s not a bad suggestion, these are my usual go-tos when diagnosing cause.
But then a query into what the sources are for this information is:
> The information is based on common knowledge about Java security, SSL/TLS configurations, and best practices for handling certificates. It reflects general principles and troubleshooting steps recognized in Java development and security documentation. If you're looking for specific references, the Oracle documentation on Java security and the keytool command, as well as community forums and resources on SSL/TLS issues, often cover these topics.
