Re: [Trustedjava-support] Exception in pki-server

[Carolin L. <car...@un...>]

Got it working!!! :-)

I had to add iaik_jtss_tcs.jar to the classpath in pki_server.sh ( I do
not understand, why I have to add iaik_jtss_tsp.jar to the system's
classpath and iaik_jtss_tcs.jar to the temporary classpath.... but that
doesn't matter as long as there is a working solution).

But there are still some strange things:

If I ask my server for an EK certificate, the answer is:

Validating XKMS message signature using certificate:
  CN=IAIK OpenTC XKMS Test Responder,OU=IAIK trusted computing
labs,O=Graz University of Technology,C=AT
XKMS Result message signature is INVALID.

received EK certificate #20080118133421135
exported to file: tybble_ek.cert

That does not happen with your server. I generated my server
certificates using tccert ca.ini and build_certs.sh.

I think, the following server error is a consequence from the one above:

javax.crypto.BadPaddingException: Invalid PKCS#1 padding: no leading zero!
