Hi fellow TPM developers,
I currently work on a project implementing some functionality of the TPM on
a windows 7 plattform. Unfortunatly I did not come that far, and was stoped
by a fatal considering further progress.
What I have:
Windows 7
Trousers for Windows (provided by TORSEC)
TPM 1.2 with taken ownership
What I try to do:
Loading the basic handles as discribed in a variety of documentations and
papers.
[...]
TSS_UUID SRK_UUID = TSS_UUID_SRK;
[...]
// Get the SRK handle
result = Tspi_Context_LoadKeyByUUID(hContext,
TSS_PS_TYPE_SYSTEM,
SRK_UUID,
&hSRK);
DBG("Got the SRK handle", result);
[...]
The problem:
As discribed in the title I encounter the following error:
Error 0x2020 "Key not found in persistent storage"
Because this is the SRK handle, I unfortunatly fail to build anything
related to it ... which is pretty much everything :D
Can somebody help me plz :)
A subquestion of mine would be the following:
What exactly does SRK_UUID = TSS_UUID_SRK do? As I did not claim the
ownership with the provided TSS, but instead with the Windows 7 API I
assume the problem could be related to that.
Additionally I did not found what is the diference between
TSS_PS_TYPE_SYSTEM and TSS_PS_TYPE_USER.
I thank you for all help provided,
Sincerely
Marius
