篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了VBS脚本获取安全标识符SID(Security Identifiers)的方法相关的知识,希望对你有一定的参考价值。
一、SID简介
SID也就是安全标识符(Security Identifiers),是标识用户、组和计算机帐户的唯一的号码。在第一次创建该帐户时,将给网络上的每一个帐户发布一个唯一的 SID。Windows 2000 中的内部进程将引用帐户的 SID 而不是帐户的用户或组名。如果创建帐户,再删除帐户,然后使用相同的用户名创建另一个帐户,则新帐户将不具有授权给前一个帐户的权力或权限,原因是该帐户 具有不同的 SID 号。安全标识符也被称为安全 ID 或 SID。
一个完整的SID包括:
? 用户和组的安全描述
? 48-bit的ID authority
? 修订版本
? 可变的验证值Variable sub-authority values
例:S-1-5-21-343818398-299502267-839522115-500

二、VBS脚本获取SID
方法一:
strComputer = objNetwork.ComputerName‘获取当前的机器名
strUserName=objNetwork.UserName‘获取当前的用户名
Set objLocalSam =GetObject("WinNT://" & strComputer & "/" & strUserName)‘这里做了修改,scottlocke中默认strUserName为"Administrator"是不保险的
Wscript.echo SIDArray(objLocalSam.objectSID)
Function SIDArray(bar)
‘ Converts Binary Array into Human readable eg: S-1-5-21-XXXXX-XXXXX-XXXXX-XXX
dim seperator,sid,length
seperator = ""
sid = ""
for length = 1 to lenb(bar)
sid = sid & seperator & right("0" & hex(ascb(midb(bar,length,1))),2)
seperator = ","
Next
SIDArray = sid
SID = Split(SIDArray,",")
‘ Convert into standard viewable format - little endian format for 4 byte groups
SID1 = (HexToDec(Mid(SID(15), 1, 1))*268435456) + (HexToDec(Mid(SID(15), 2, 2))*16777216) + (HexToDec(Mid(SID(14), 1, 1))*1048576) + (HexToDec(Mid(SID(14), 2, 2))*65536) + (HexToDec(Mid(SID(13), 1, 1))*4096) + (HexToDec(Mid(SID(13), 2, 2))*256) + (HexToDec(Mid(SID(12), 1, 1))*16) + HexToDec(Mid(SID(12), 2, 2))
SID2 = (HexToDec(Mid(SID(19), 1, 1))*268435456) + (HexToDec(Mid(SID(19), 2, 2))*16777216) + (HexToDec(Mid(SID(18), 1, 1))*1048576) + (HexToDec(Mid(SID(18), 2, 2))*65536) + (HexToDec(Mid(SID(17), 1, 1))*4096) + (HexToDec(Mid(SID(17), 2, 2))*256) + (HexToDec(Mid(SID(16), 1, 1))*16) + HexToDec(Mid(SID(16), 2, 2))
SID3 = (HexToDec(Mid(SID(23), 1, 1))*268435456) + (HexToDec(Mid(SID(23), 2, 2))*16777216) + (HexToDec(Mid(SID(22), 1, 1))*1048576) + (HexToDec(Mid(SID(22), 2, 2))*65536) + (HexToDec(Mid(SID(21), 1, 1))*4096) + (HexToDec(Mid(SID(21), 2, 2))*256) + (HexToDec(Mid(SID(20), 1, 1))*16) + HexToDec(Mid(SID(20), 2, 2))
RID = (HexToDec(Mid(SID(27), 1, 1))*268435456) + (HexToDec(Mid(SID(27), 2, 2))*16777216) + (HexToDec(Mid(SID(26), 1, 1))*1048576) + (HexToDec(Mid(SID(26), 2, 2))*65536) + (HexToDec(Mid(SID(25), 1, 1))*4096) + (HexToDec(Mid(SID(25), 2, 2))*256) + (HexToDec(Mid(SID(24), 1, 1))*16) + HexToDec(Mid(SID(24), 2, 2))
‘ Cheating here by just prepending the S-1-5-21-
SIDArray = "S-1-5-21-" & SID1 & "-" & SID2 & "-" & SID3 & "-" & RID
End Function
Function HexToDec(ByVal sHex)
HexToDec = "" & CLng("&H" & sHex)
End Function

方法二:
On Error Resume Next
Dim oWMI, oAs, oA, sSid
Set oWMI = GetObject("winmgmts:\\.\root\cimv2")
If strUser <> "" Then
Set oAs = oWMI.ExecQuery("Select SID From Win32_Account" & _
" WHERE SIDType=1 AND Name=‘" & strUser & "‘")
For Each oA In oAs
sSid= Mid(oA.SID, InStrRev(oA.SID, "-") + 1)
WScript.Echo "Short SID: " & sSid & " (" & HEX(sSid) & "H)"
Next
Else
Set oAs = oWMI.ExecQuery("Select Name, SID From Win32_Account WHERE SIDType=1")
For Each oA In oAs
WScript.Echo "User: " & oA.Name & _
vbCrLf & vbTab & "SID: " & oA.SID
Next
End If
Set oA = Nothing
Set oAs = Nothing
Set oWMI = Nothing
If Err.Number <> 0 Then
WScript.Echo "Error ocurred: " & Err.Description
Err.Clear
End If
End Function
