您好，我拜读了您的大作，有一些疑问想跟您沟通一下。
我看到文中提到ProtoHeader的定义如下

typedef struct {
    uint32 linedefined;
    uint32 lastlinedefined;
    uchar numparams;
    uchar is_vararg;
    uchar maxstacksize;
} ProtoHeader;

但是我看到lua5.1.5的代码中这部分代码是这样的

static void DumpFunction(const Proto* f, const TString* p, DumpState* D)
{
 DumpString((f->source==p || D->strip) ? NULL : f->source,D);
 DumpInt(f->linedefined,D);
 DumpInt(f->lastlinedefined,D);
 **DumpChar(f->nups,D);**
 DumpChar(f->numparams,D);
 DumpChar(f->is_vararg,D);
 DumpChar(f->maxstacksize,D);
 DumpCode(f,D);
 DumpConstants(f,D);
 DumpDebug(f,D);
}

我的疑问是nups是否在ProtoHeader中被遗漏了？

老哥，有没有luac解密的工具，我有KEY和SIGN了
