一般的模块<Module>是个空类，但是遇到一个处理过的。处理方法不清楚。

这个类构有非空造函数和方法,调用了VirtualProtect，方法名是空字符串。

internal class <Module>
{
	static <Module>()
	{
		<Module>.*‪‪‬​‫‬*‪‎‎****‫‫‎*‬‬‏‏*‪‎‏‎*();
	}

	[System.Runtime.InteropServices.DllImport("kernel32.dll", EntryPoint = "VirtualProtect")]
	internal static extern bool ‏*‏*‪***‬‪‏​​*‏‫‬*​‎*‪‏‬‏*(System.IntPtr, uint, uint, ref uint);

	internal unsafe static void *‪‪‬​‫‬*‪‎‎****‫‫‎*‬‬‏‏*‪‎‏‎*()
	{
		System.Reflection.Module module = typeof(<Module>).Module;
		string fullyQualifiedName = module.FullyQualifiedName;
		bool flag = fullyQualifiedName.Length > 0 && fullyQualifiedName[0] == '<';
		byte* ptr = (byte*)((void*)System.Runtime.InteropServices.Marshal.GetHINSTANCE(module));
		byte* ptr2 = ptr + *(uint*)(ptr + 60);
		ushort num = *(ushort*)(ptr2 + 6);
		ushort num2 = *(ushort*)(ptr2 + 20);
		uint* ptr3 = null;
		uint num3 = 0u;
		uint* ptr4 = (uint*)(ptr2 + 24 + num2);
		uint num4 = 1944716907u;
		uint num5 = 3396842843u;
		uint num6 = 144243033u;
		uint num7 = 1918455554u;
		for (int i = 0; i < (int)num; i++)
		{
			uint num8 = *(ptr4++) * *(ptr4++);
			if (num8 == 3512859536u)
			{
				ptr3 = (uint*)(ptr + (flag ? ptr4[3] : ptr4[1]) / 4u);
				num3 = (flag ? ptr4[2] : (*ptr4)) >> 2;
			}
			else if (num8 != 0u)
			{
				uint* ptr5 = (uint*)(ptr + (flag ? ptr4[3] : ptr4[1]) / 4u);
				uint num9 = ptr4[2] >> 2;
				for (uint num10 = 0u; num10 < num9; num10 += 1u)
				{
					uint num11 = (num4 ^ *(ptr5++)) + num5 + num6 * num7;
					num4 = num5;
					num5 = num7;
					num7 = num11;
				}
			}
			ptr4 += 8;
		}
		uint[] array = new uint[16];
		uint[] array2 = new uint[16];
		for (int j = 0; j < 16; j++)
		{
			array[j] = num7;
			array2[j] = num5;
			num4 = (num5 >> 5 | num5 << 27);
			num5 = (num6 >> 3 | num6 << 29);
			num6 = (num7 >> 7 | num7 << 25);
			num7 = (num4 >> 11 | num4 << 21);
		}
		array[0] = (array[0] ^ array2[0]);
		array[1] = array[1] * array2[1];
		array[2] = array[2] + array2[2];
		array[3] = (array[3] ^ array2[3]);
		array[4] = array[4] * array2[4];
		array[5] = array[5] + array2[5];
		array[6] = (array[6] ^ array2[6]);
		array[7] = array[7] * array2[7];
		array[8] = array[8] + array2[8];
		array[9] = (array[9] ^ array2[9]);
		array[10] = array[10] * array2[10];
		array[11] = array[11] + array2[11];
		array[12] = (array[12] ^ array2[12]);
		array[13] = array[13] * array2[13];
		array[14] = array[14] + array2[14];
		array[15] = (array[15] ^ array2[15]);
		uint num12 = 64u;
		<Module>.‏*‏*‪***‬‪‏​​*‏‫‬*​‎*‪‏‬‏*((System.IntPtr)((void*)ptr3), num3 << 2, num12, ref num12);
		uint num13 = 0u;
		for (uint num14 = 0u; num14 < num3; num14 += 1u)
		{
			*ptr3 ^= array[(int)((System.UIntPtr)(num13 & 15u))];
			array[(int)((System.UIntPtr)(num13 & 15u))] = (array[(int)((System.UIntPtr)(num13 & 15u))] ^ *(ptr3++)) + 1035675673u;
			num13 += 1u;
		}
	}
}

还有第二个模块名为ConfusedByAttribute,继承System.Attribute
仅有一个构造函数

.method public hidebysig specialname rtspecialname 
        instance void  .ctor(string A_1) cil managed
{
  // 代码大小       0 (0x0)
} // end of method ConfusedByAttribute::.ctor

问题就是用Mono.Cecil读取一些类和方法都会报异常。
第一种是这样的：
---> System.InvalidOperationException: 对象的当前状态使该操作无效。
   在 Mono.Cecil.Cil.CodeReader.ReadMethodBody()
   在 Mono.Cecil.Cil.CodeReader.ReadMethodBody(MethodDefinition method)
   在 Mono.Cecil.MethodDefinition.<get_Body>b__2(MethodDefinition method, MetadataReader reader)
   在 Mono.Cecil.ModuleDefinition.Read[TItem,TRet](TRet& variable, TItem item, Func`3 read)
   在 Mono.Cecil.MethodDefinition.get_Body()

第二种是这样的：
---> System.IndexOutOfRangeException: 索引超出了数组界限。
   在 Mono.Cecil.Cil.CodeReader.ReadOpCode()
   在 Mono.Cecil.Cil.CodeReader.ReadCode()
   在 Mono.Cecil.Cil.CodeReader.ReadMethodBody()
   在 Mono.Cecil.Cil.CodeReader.ReadMethodBody(MethodDefinition method)
   在 Mono.Cecil.MethodDefinition.<get_Body>b__2(MethodDefinition method, MetadataReader reader)
   在 Mono.Cecil.ModuleDefinition.Read[TItem,TRet](TRet& variable, TItem item, Func`3 read)
   在 Mono.Cecil.MethodDefinition.get_Body()

ILDasm也试过，也是不能正确读取，提示类型多样
.method private hidebysig instance void  CallHome() cil managed
{
  // 代码大小       61 (0x3d)
  .maxstack  8
  IL_0000:  stind.i1
  IL_0001:  conv.u
  IL_0002:  br.s       IL_fffffff4
  IL_0004:  conv.ovf.i2
  IL_0005:  conv.ovf.i
  IL_0006:  conv.r8
  IL_0007:  ldc.i4.1
  IL_0008:  unused
  IL_0009:  bgt.un.s   IL_0018
  IL_000b:  stloc.s    V_159
  IL_000d:  ldc.i8     0x352bd1adfed9a6aa
  IL_0016:  unused
  IL_0017:  unused
  IL_0018:  conv.i2
  IL_0019:  brtrue.s   IL_009a
  IL_001b:  nop
  IL_001c:  unused
  IL_001d:  unused
  IL_001e:  unused
  IL_001f:  ldc.r4     -2.3178437e-008
  IL_0024:  unused
  IL_0025:  conv.u8
// ***指令解码错误: F8 (在位置 0x26 (38)处)
} // end of method CallHomeService::CallHome

也有这样的
.method private hidebysig static class [System]System.Uri
        GetHostUri() cil managed
{
  // 代码大小       9 (0x9)
  .maxstack  8
  IL_0000:  unused
  IL_0001:  conv.ovf.i
  IL_0002:  conv.i4
  IL_0003:  shl
  IL_0004:  unused
  IL_0005:  bge.un.s   IL_001f
  IL_0007:  unused
  IL_0008:  ldflda      [ERROR: INVALID TOKEN 0xA7E38F44]
} // end of method CallHomeService::GetHostUri

有没有遇到过这种情况的，求加密原理和反编译方法！
