似乎没有用于此任务的文档化 API,不管是托管的还是其他的。
托管尝试
我使用System.Management 程序集尝试了托管路由:
ConnectionOptions options = new ConnectionOptions();
ManagementScope scope = new ManagementScope(@"\\.\root\RSOP\Computer", options);
ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, new ObjectQuery("SELECT * FROM RSOP_SecuritySettingBoolean"));
foreach(ManagementObject o in searcher.Get())
{
Console.WriteLine("Key Name: {0}", o["KeyName"]);
Console.WriteLine("Precedence: {0}", o["Precedence"]);
Console.WriteLine("Setting: {0}", o["Setting"]);
}
但这不会返回结果。这似乎不是权限问题,因为向 ConnectionOptions 提供用户名/密码对会导致异常告诉您在本地连接时无法指定用户名。
非托管尝试
我看了NetUserModalsGet。虽然这会返回一些关于密码设置的信息:
typedef struct _USER_MODALS_INFO_0 {
DWORD usrmod0_min_passwd_len;
DWORD usrmod0_max_passwd_age;
DWORD usrmod0_min_passwd_age;
DWORD usrmod0_force_logoff;
DWORD usrmod0_password_hist_len;
} USER_MODALS_INFO_0, *PUSER_MODALS_INFO_0, *LPUSER_MODALS_INFO_0;
..它不会告诉Password Complexity 策略是否启用。
工具输出抓取“成功”
所以我求助于解析secedit.exe 输出。
public static bool PasswordComplexityPolicy()
{
var tempFile = Path.GetTempFileName();
Process p = new Process();
p.StartInfo.FileName = Environment.ExpandEnvironmentVariables(@"%SystemRoot%\system32\secedit.exe");
p.StartInfo.Arguments = String.Format(@"/export /cfg ""{0}"" /quiet", tempFile);
p.StartInfo.CreateNoWindow = true;
p.StartInfo.UseShellExecute = false;
p.Start();
p.WaitForExit();
var file = IniFile.Load(tempFile);
IniSection systemAccess = null;
var passwordComplexityString = "";
var passwordComplexity = 0;
return file.Sections.TryGetValue("System Access", out systemAccess)
&& systemAccess.TryGetValue("PasswordComplexity", out passwordComplexityString)
&& Int32.TryParse(passwordComplexityString, out passwordComplexity)
&& passwordComplexity == 1;
}
