求问： AesEncrypt(string input, string password, string salt)这个C#函数如何转化AU3所用？
三个参数已有：
input=AAAAAA|123456（私人账号|密码）
SecretKey Password = "Z_h$W@123";
SecretKey Salt = "123@Z_h$W";
自己摸索结果：
Cryptography.AesEncrypt结果：IA6PCpe/zZEtICN7E/EFXw==
但是我采用acn论坛、英文论坛、其他在线解密网站（http://tool.chacuo.net/cryptaes），
结算结果均为错误的或其他：WznD9w7icLss4DLVThTFUQ==
其中使用英文论坛：#include <ComboConstants.au3>
#include <Crypt.au3>
#include <EditConstants.au3>
#include <GUIConstantsEx.au3>
#include <MsgBoxConstants.au3>
#include <StringConstants.au3>

以下为该函数的C#DLL，因无接口本想通过regasm注册再用au3调用，但注册失败：#PRE_UseX64=n
#RequireAdmin
Global $dll = 'Inhua.Silverlight.Common.dll'
Global $RegAsm = @ScriptDir & '\regasm.exe'
Local $obj = regdll()
Func regdll()
Local $obj = ObjCreate("Inhua.Silverlight.Common.Cryptography")
If Not IsObj($obj) Then
;~ RunWait($RegAsm & " /codebase " & $dll, @ScriptDir, @SW_HIDE) ; register the .net DLL
$obj = ObjCreate("Inhua.Silverlight.Common.Cryptography")
If Not IsObj($obj) Then
MsgBox(0, @error, '注册失败')
Exit
EndIf
EndIf
Return $obj
EndFunc ;==>regdll
如果能成功Obj调用就是最简单的解决方法了，故附上dll，望熟悉加密算法的坛友指点迷津，感激不尽！
亦可参考本文：https://blog.csdn.net/kangrydotnet/article/details/43987835（c#爬取Silverlight网页）此文解决思路基本符合。
