Bug ID: 54821
           Summary: CryptAcquireCertificatePrivateKey implementation
                    ignores CRYPT_ACQUIRE_ONLY_NCRYPT_KEY_FLAG
           Product: Wine
           Version: 8.4
          Hardware: x86-64
                OS: Mac OS X
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: crypt32
          Assignee: wine-bugs@winehq.org
          Reporter: mterrisse@free.fr
Hello,
I have recently moved all my code from Crypto API to CNG and it doesn't work
with Wine because CryptAcquireCertificatePrivateKey ignores the flag
CRYPT_ACQUIRE_ONLY_NCRYPT_KEY_FLAG.
CryptAcquireCertificatePrivateKey with dwFlags =
CRYPT_ACQUIRE_ONLY_NCRYPT_KEY_FLAG returns True, but pdwKeySpec isn't equal to
CERT_NCRYPT_KEY_SPEC and phCryptProvOrNCryptKey is a handle to a CAPI container
handle instead of a ncrypt key.
I have looked at the source code (dlls/crypt32/cert.c) and indeed there is no
reference to CRYPT_ACQUIRE_ONLY_NCRYPT_KEY_FLAG.
I will try to handle this with NCryptTranslateHandle but I think this should be
done in crypt32.dll.
Regards,
Michel Terrisse
