Conclusion

This article wraps up my coverage of X.509 certificate support in Java. You should now have the tools and understanding necessary to build your own applications using X.509 technology. It should be clear from the section on certificate validation above that you have only explored the tip of the iceberg; you can proceed in any number of directions to deepen your understanding. For the novice, I recommend learning more about existing technologies that use X.509 -- such as SSL. That path will offer you the greatest practical understanding of the material.
