Re: [Trustedjava-support] Byte order for UUIDs

Hi Christoph,

I am sorry for the late answer - and I still did not have the time to 
look into this. :-(

As a quick work-around try to instantiate your SRK key object this way.
srk_ = context_.createRsaKeyObject(TcTssConstants.TSS_KEY_TSP_SRK);

Also make sure that the SRK is actually stored in the persistent storage 
of the TrouSerS you use. This is typically performed upon taking ownership.
