Custom JSSE Truststore to enable XKMS Certificate Validation

Recently I was involved in a project which uses a central XKMS Server for certificate and trust management. This was all working fine within the Talend runtime with a custom wss4j crypto provider. However the need raised to perform client certificate validations (mutal SSL) with Apache Fediz running inside an Apache Tomcat server.


Usually I would use a JKS truststore for Tomcat to add trusted certificates (CAs). However this was not possible for this project, because all certificates will be managed inside an LDAP accessible via a XKMS service. Searching for a solution to extend Tomcat to support XKMS based certificate validation I came across the JSSE Standard.

Reading throw the documentation was not so straightforward and clear. But searching through the internet finally helped me to achieve my goal. In this blog post, I'll show you what I had to do, to enabled XKMS based SSL certificate validation in Tomcat.
