Hello, I have been trying to implement a solution using the tpm2-tss FAPI to talk to a Windows TPM, via the TCTI TBS. I have used the FAPI successfully on Linux and thought that by using the Visual Studio existing solution in tpm2-tss and porting the tpm2-tss FAPI on top I might be able to have something working. Whilst part of the solution seems to work, the Windows TPM has been uncooperative on a lot of instances, first during the startup sequence when trying to get capabilities, among other things. I'm also assuming the provisioning process based on the fapi profiles process will not work for TBS. My question is simple, has there ever been a successful ESYS implementation on Windows ? One with examples I might be able to base myself on to try and make it work ? I might be a bit green when it comes to working with TPMs so I apologize if my request seems ignorant. Thanks in advance for your help Regards, Alexis Garnier
