Bye the looks of it they dont have it working either

their version:
BOOL WINAPI DecryptFileW(LPCWSTR lpFileName, DWORD dwReserved)
{
    DPRINT1("%s(%S) not implemented!\n", __FUNCTION__, lpFileName);
    SetLastError(ERROR_CALL_NOT_IMPLEMENTED);
    return FALSE;
}
our version:
BOOL WINAPI DecryptFileW(LPCWSTR lpFileName, DWORD dwReserved)
{
    FIXME("(%s, %08x): stub\n", debugstr_w(lpFileName), dwReserved);
    return TRUE;
}

Only real difference is ours returns true while theres returns false. From what
I read here: http://technet.microsoft.com/en-ca/aa363903%28v=vs.80%29.aspx it
is suppose to return 0 or false when it fails. So I changed the wine version to
return false which resulted in the program closing once it hit the fixme
instead of waiting for me to kill it.

Does anyone know how one would go about implementing windows encryption
functions? Is it even possible?
