先贴一段代码,是一个简单的运算.然后用混淆器进行业务逻辑的混淆...
下面开始慢慢混淆了,看看...
算了,不继续了,没时间去写很复杂的...反正大家兴一反三吧.
基本上没有起到作用,代码如下.
Dim a, b, c, d As String
d = 50
c = d
b = c
a = b
b = 20
d = 30
Dim s As Decimal
s = a + b + c * d
MsgBox(s)
--------------------------------
对比混淆后
--------------------------------
private void a(object A_0, EventArgs A_1)
{ string text1;
string text2;
string text3;
string text4;
decimal num1;
text4 = StringType.FromInteger(50);
text3 = text4;
text2 = text3;
text1 = text2;
text2 = StringType.FromInteger(20);
text4 = StringType.FromInteger(30);
num1 = new decimal((DoubleType.FromString(string.Concat(text1, text2)) + (DoubleType.FromString(text3) * DoubleType.FromString(text4))));
Interaction.MsgBox(num1, 0, null);
}
--------------------------
源代码为:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim a, b, c, d As Integer
d = 50
c = d
b = c
a = b
b = 20
d = 30
Dim s As Decimal
Swap(d, c)
s = add(a, add(b, c)) * c
MsgBox(s)
End Sub
Function add(ByVal a As Integer, ByVal b As Integer) As Integer
Return a + b
End Function
Function Swap(ByRef a As Integer, ByRef b As Integer)
Dim aa As Integer
aa = a
a = b
b = aa
End Function
--------------------------------------------
之后为
--------------------------------------------
private void a(object A_0, EventArgs A_1)
{ int num1;
int num2;
int num3;
int num4;
decimal num5;
num4 = 50;
num3 = num4;
num2 = num3;
num1 = num2;
num2 = 20;
num4 = 30;
this.a(&(num4), &(num3));
num5 = new decimal((this.a(num1, this.a(num2, num3)) * num3));
Interaction.MsgBox(num5, 0, null);
}
public object a(ref int A_0, ref int A_1)
{ int num1;
object obj1;
num1 = A_0;
A_0 = A_1;
A_1 = num1;
return obj1;
}
public int a(int A_0, int A_1)
{ int num1;
return (A_0 + A_1);
}
-----------------------------
读一读?是不是有些困难了些,当然,我是把代码都直接粘出来了,你读起来还方便点,但是...如果从几十个或是上面个....
比方说,有意的制作一个大的Class,再把Class中混淆...哇.头痛的事来了.
决窍就是调用...功能写在函数,写成类,使用对象.类与类之间可能有关系...当然,还是结构逻辑第一...不要为了故意混淆搞到自己都看不懂...或看起来麻烦.
有些事情可以在项目完成的那段时间再做
有不正确之处,请指出...我对这个研究也很肤浅,如果有什么想法也可以提出...说不定咱们自己还可以搞个什么比这个更好的东东...
