Hello. I am a little confused about using the tpm. I need to do a project to
encrypt a file, but I am having some trouble. I am working with the TSS stack.
Can someone point me into a direction? So the tpm holds the keys, but we can
not export them like using openssl. They are kept secure into the tpm. But if I
want to use them to encrypt something, how can I get to them.
I tryed a couple of things, but no succes. Right now I tried creating a key
with
Tspi_Context_CreateObject(hContext,TSS_OBJECT_TYPE_RSAKEY,initFlags,&hKey);
Tspi_Key_CreateKey(hKey,hSRK,0); and now i am stuck.
Should I use this key to do a Tspi_Data_Bind? if yes i have a question. The
result of this function will be an encrypted blob?
Theoretical I should encrypt a text file using an symmetric key, but can't
really put my fingers on it. Is it possible to use the rsa public key blob that
is found in the EK to encrypt a text?
