Re: [Trustedjava-support] Legacy keys

Hi, Thanks for the clarification. I was also wondering it is actually so that a legacy key can ONLY be an external RSA key, or whether the TPM should also be able to internally generate a legacy key according to the specs, but the functionality is not offered by the JSR 321?

Subject: Re: [Trustedjava-support] Legacy keys Hi Federico, You're right, the TPM spec does allow binding and unbinding with legacy keys. Yet, the JSR321 API specification does not. Actually the functionality did not occur to the JSR321 expert group at the time of writing the spec.. :-/ Feel free to add the functionality to your Binder implementation.

I can see that the Signer object also has a method that accepts legacy keys, but what about encryption? Should I use an external library to do that? And if so, how do I decrypt the data with the private key, if only the TPM has access to it? I thought of the Binder and RemoteBinder objects, which are the only ones that have to do with encryption, but they do not accept Legacy keys. > Any tips? > > Thanks! > > Federico > > ---------------------------------------------------------------------- > -------- LogMeIn Central: Instant, anywhere, Remote PC access and > management. > Stay in control, update software, and manage PCs from one command > center Diagnose problems and improve visibility into emerging IT > issues Automate, monitor and manage.
