Hey John,
I'm not sure about the return code.
But some other comments here:
1) I've used Tspi_ContextCreateObject(...) to create AIK objects with
success. I guess CreateKey() should work too, seems logical. I'm not sure
how I ended up using CreateObject(), I'm guessing I followed someone else's
example:
UINT32 initFlags = TSS_KEY_TYPE_IDENTITY | TSS_KEY_SIZE_2048 |
TSS_KEY_AUTHORIZATION |
TSS_KEY_VOLATILE | TSS_KEY_NOT_MIGRATABLE;
result = Tspi_Context_CreateObject(hContext,
TSS_OBJECT_TYPE_RSAKEY,
initFlags, &hIdentKey);
2) Even if CreateKey() should work, it looks like you are passing in your
PCA server public key as the first argument (hPCA)? This should be the
handle to your new key, I think, so if this is a TSS KEY object that you
created from DER that the user passed in (deduced from Andrew's comments
below), I don't think that would work anyway. The PCA key material is not
used until the CollateIdentityRequest() step.
