完整注入流程示例
结语1. 设计哲学：零外部依赖
许多保护工具要求用户分发运行时 DLL（如 VMProtectSDK32.dll）。我们的设计：所有运行时类型在保护时完整克隆到目标程序集。2. InjectHelper：dnlib 深度克隆引擎
public static class InjectHelper
{// === 入口 1：克隆整个类型到目标模块 ===public static TypeDef Inject(TypeDef typeDef, ModuleDef target){var ctx = new InjectContext(typeDef.Module, target);return (TypeDef)ctx.Import(typeDef);}// === 入口 2：克隆单个方法 ===public static MethodDef Inject(MethodDef methodDef, ModuleDef target){var ctx = new InjectContext(methodDef.Module, target);return (MethodDef)ctx.Import(methodDef);}// === 入口 3：批量克隆（共享上下文，处理交叉引用） ===public static ListTypeDef InjectMany(IEnumerableTypeDef typeDefs, ModuleDef target){var ctx = new InjectContext(typeDefs.First().Module, target);return typeDefs.Select(t = (TypeDef)ctx.Import(t)).ToList();}
}克隆管道：浅拷贝 → 深拷贝 → 签名修复
class InjectContext : ImportMapper
{// 映射表：origin → cloneDictionaryIMemberRef, IMemberRef _map = new();IMemberRef Import(IMemberRef member){// 1. 已克隆？→ 直接返回映射if (_map.TryGetValue(member, out var mapped))return mapped;// 2. 根据类型深度克隆return member switch{TypeDef td = Clone(td),MethodDef md = Clone(md),FieldDef fd = Clone(fd),TypeRef tr = TargetModule.Import(tr),MemberRef mr = TargetModule.Import(mr),_ = member};}TypeDef Clone(TypeDef origin){var clone = new TypeDefUser(origin.Namespace, origin.Name){Attributes = origin.Attributes,BaseType = Import(origin.BaseType)};// 记录映射_map[origin] = clone;// 克隆接口foreach (var iface in origin.Interfaces)clone.Interfaces.Add(new InterfaceImplUser(Import(iface.Interface)));// 克隆属性foreach (var prop in origin.Properties)clone.Properties.Add(Clone(prop));// 克隆字段foreach (var field in origin.Fields)clone.Fields.Add(Clone(field));// 克隆方法（含方法体 IL）foreach (var method in origin.Methods)clone.Methods.Add(Clone(method));return clone;}MethodDef Clone(MethodDef origin){var clone = new MethodDefUser(origin.Name,Import(origin.MethodSig),origin.ImplAttributes,origin.Attributes);_map[origin] = clone;// 克隆方法体（IL 指令、局部变量、异常处理器）if (origin.HasBody){clone.Body = new CilBody();clone.Body.InitLocals = origin.Body.InitLocals;clone.Body.MaxStack = origin.Body.MaxStack;// 复制局部变量foreach (var local in origin.Body.Variables)clone.Body.Variables.Add(new Local(Import(local.Type)));// 复制 IL 指令（映射操作数）foreach (var instr in origin.Body.Instructions){var cloneInstr = new Instruction(instr.OpCode,MapOperand(instr.Operand));clone.Body.Instructions.Add(cloneInstr);}// 复制异常处理器foreach (var eh in origin.Body.ExceptionHandlers){clone.Body.ExceptionHandlers.Add(new ExceptionHandler(eh.HandlerType){CatchType = Import(eh.CatchType),TryStart = Map(eh.TryStart),TryEnd = Map(eh.TryEnd),HandlerStart = Map(eh.HandlerStart),HandlerEnd = Map(eh.HandlerEnd),});}}return clone;}
}3. InjectContext：ImportMapper 与框架重定向
.NET Core 的 UI 外观程序集（System.Runtime.dll 等）需要重定向到核心库：
public override IMemberRef Map(IMemberRef member)
{var asm = member.DeclaringType?.DefinitionAssembly;if (asm == null) return base.Map(member);// 0a. .NET Framework 目标遇到 System.Private.CoreLib → 重定向到 mscorlibif (!TargetIsNetCore IsCoreLib(asm))return RedirectTo(asm, TargetModule.CorLibTypes.AssemblyRef);// 0. 外观程序集 → 重定向到 System.Private.CoreLib 或 mscorlibif (IsFacadeAssembly(asm)){var corlib = TargetModule.CorLibTypes.AssemblyRef;return RedirectTo(asm, corlib);}// 1. 目标模块已有同名引用？→ 使用已有的var existingRef = TargetModule.GetAssemblyRef(asm.Name);if (existingRef != null existingRef.Version == asm.Version)return existingRef;return base.Map(member);
}static readonly HashSetstring _facadeAsmNames = new()
{"System.Runtime", "System.IO", "System.Linq", "System.Collections","System.Threading", "System.Reflection", "System.Diagnostics","netstandard", "System.Net.Http", "System.ComponentModel",// ... 40+ 个框架外观程序集
};4. MutationHelper：占位符替换引擎
public static class MutationHelper
{// 映射：Mutation 字段名 → key 索引static readonly Dictionarystring, int field2index = new(){{ "KeyI0", 0 }, { "KeyI1", 1 }, { "KeyI2", 2 }, { "KeyI3", 3 },{ "KeyI4", 4 }, { "KeyI5", 5 }, { "KeyI6", 6 }, { "KeyI7", 7 },{ "KeyI8", 8 }, { "KeyI9", 9 }, { "KeyI10", 10 }, { "KeyI11", 11 },{ "KeyI12", 12 }, { "KeyI13", 13 }, { "KeyI14", 14 }, { "KeyI15", 15 },};// 替换 Key 占位符public static void InjectKey(MethodDef method, int keyId, int value){foreach (var instr in method.Body.Instructions){if (instr.OpCode != OpCodes.Ldsfld) continue;var field = (IField)instr.Operand;// TWSoft.Runtime.Mutation.KeyI0 → ldc.i4 valueif (field.DeclaringType.Name == "Mutation" field2index.TryGetValue(field.Name, out int id) id == keyId){instr.OpCode = OpCodes.Ldc_I4;instr.Operand = value;}}}// 替换 Placeholder 调用public static void ReplacePlaceholder(MethodDef method,FuncInstruction[], Instruction[] repl){foreach (var instr in method.Body.Instructions.ToList()){if (instr.OpCode != OpCodes.Call) continue;var called = (IMethod)instr.Operand;// Mutation.PlaceholderT(T val) → 替换为真实指令序列if (called.Name == "Placeholder"){// 追踪参数来源Instruction[] argInstructions = TraceArguments(instr);// 移除原 call 指令int index = method.Body.Instructions.IndexOf(instr);method.Body.Instructions.RemoveAt(index);// 插入替换指令var replacement = repl(argInstructions);foreach (var replInstr in replacement.Reverse())method.Body.Instructions.Insert(index, replInstr);}}}
}5. RuntimeService：从保护工具自身加载运行时
public sealed class RuntimeService
{ModuleDef? _rtModule;public TypeDef GetRuntimeType(string fullName){_rtModule ??= LoadSelfModule(); // 首次调用懒加载return _rtModule.Find(fullName, true)?? throw new InvalidOperationException($"Runtime type '{fullName}' not found");}static ModuleDef LoadSelfModule(){var asm = typeof(RuntimeService).Assembly;return ModuleDefMD.Load(asm.Location,new ModuleCreationOptions { TryToLoadPdbFromDisk = false });}
}使用示例：
var runtime = context.Runtime; // 从 ProtectionContext 获取
var constantType = runtime.GetRuntimeType("TWSoft.Runtime.Constant");
var clonedConstant = InjectHelper.Inject(constantType, context.Module); // 克隆6. 完整注入流程示例
以字符串加密为例，完整注入流程：
// Step 1: 获取运行时类型模板
var constantType = context.Runtime.GetRuntimeType("TWSoft.Runtime.Constant");// Step 2: 深度克隆到目标模块
var clonedType = InjectHelper.Inject(constantType, context.Module);// Step 3: 替换占位符为真实值
var initMethod = clonedType.FindMethod("Initialize");
MutationHelper.InjectKey(initMethod, 0, bufferLength); // KeyI0 → 真实长度
MutationHelper.InjectKey(initMethod, 1, seed); // KeyI1 → 真实种子
MutationHelper.ReplacePlaceholder(initMethod, args = // Placeholder → 数组初始化 ILCreateArrayInitInstructions(args));// Step 4: 重命名注入成员为不可见 Unicode
foreach (var method in clonedType.Methods)method.Name = GenerateInvisibleName(random);// Step 5: 标记不可被混淆
MarkAsNotRenameable(clonedType);// Step 6: 插入 Module.cctor 初始化调用
InsertCctorCall(context.Module, clonedType, "Initialize");7. 结语
InjectHelper + MutationHelper + RuntimeService 构成了整个保护引擎的基础设施。所有运行时类型（Constant、MethodGuard、VirtualMachine、AntiTamper、AntiDebug、AntiDump、ResourceEncryptor）都通过这条管道交付给目标程序集——零外部依赖、完全自包含。
