The chain is made of a server certificate, an intermediate CA certificate, and a root self-signed certificate.The validation outcome is ok if the input is: The validation failed, with unhandled extensions key usage and basic constraints, if the input is the whole certificate chain.I have tried going back to older version of Java but the popup still remains.

As I mentioned at the start of the chapter, the issue of knowing whether a particular certificate path is valid is more than just knowing that each certificate on the path has a signature you can validate.

Knowing whether a path is valid is also about whether the certificates you have are being used in the manner intended.

However i'm having a lot of problems getting into one customers Access Gateway VPX 10.0 We can get into it, when it then loads the Java parts it comes up with 'Failed to validate certificate' and it won't be executed.

I have turned all the security options off in Java and added the site to exceptions but will not work. When going into more information, I find out which certificate it is trying to use, and it seems to be an expired intermediate Thawte certificate.

For example, a certificate authorized to be used to encrypt secret keys might not be appropriate for validating the signature on a piece of executable code.

Certificate path validation algorithms are provided to make sure the certificate is valid in all these senses.

You can disable this check, because you have start the applet to access your FC Switch.

Verifying digital signatures: here we want to show how to verify the digital signature of a message.

Can someone point me out how can I correctly validate a chain using also system root certificates? It would be useful to check them in case there is something else going on.
