I recently upgraded IPT with PKI from v126.96.36.199 to v188.8.131.52, then I could not use CryptImportKey any more.
Because it returned 0x000000b7(maybe ERROR_ALREADY_EXISTS) after PIN setting PTD displayed.
Only container created.
I set dwFlags as CRYPT_USER_PROTECTED to use PKI with PTD.
I did not change any source codes, but only changed provider from Intel IPT Enhanced Cryptographic Provider to Intel IPT CSP - Non-Exportable Keys.
and tested on every machine what I have, but the result was not changed.
According to the Release Notes,
Intel IPT Enhanced Cryptographic Provider The name of this CSP has been changed to: “Intel IPT CSP – Non-Exportable Keys”.
The functionality of the CSP has not changed.
I think that certificate import should be allowed. if not, it is bug.
What is wrong with it? or any misuse?
Is there any solution to it?
Thank you in advance.
