RegGetKeySecurity and RegSetKeySecurity - result missmatch?

[Marco]

Hello,

I've created a virtual registry key and would like to set a security descriptor for this new key by calling RegSetKeySecurity(). This function returns with 0.
But when calling RegGetKeySecurity() the returned security descriptor doesn't match against the parameter in RegSetKeySecurity().

my pseudo code:

Code: Select all

    HKEY keyRes;
    DWORD disposition = 0;

    LONG ret = BoxedAppSDK_CreateVirtualRegKeyA(    HKEY_CURRENT_USER,
                                                    "Software\\MyTestKey123",
                                                    0,
                                                    NULL,
                                                    REG_OPTION_NON_VOLATILE,
                                                    KEY_ALL_ACCESS,
                                                    NULL,
                                                    &keyRes,
                                                    &disposition );

ret = RegSetKeySecurity( keyRes, GROUP_SECURITY_INFORMATION, desc );

PSECURITY_DESCRIPTOR tmpDesc = new unsigned char [ 200 ];
DWORD tmpSize = 200;

ret = RegGetKeySecurity( keyRes,
   GROUP_SECURITY_INFORMATION,
     tmpDesc,
     &tmpSize
   );


Thanking you in anticipation.

Hello,

Thank you for your question.

Actually, setting a security descriptor for a virtual key doesn't affect, because boxedapp doesn't support security information for virtual keys.

Do you really need it?

Thank you!
