说明：以VC++6的花指令为例说明

//VC++6外衣 1

OEPCODEFIVE: THEAD =

($55, $8B, $EC, $6A, $FF, $68, $00, $00, $00, $00, $68, $00, $00, $00, $00, $64,

$A1, $00, $00, $00, $00, $50, $64, $89, $25, $00, $00, $00, $00, $83, $EC, $68,

$53, $56, $57, $58, $58, $58, $83, $C4, $68, $58, $67, $64, $A3, $00, $00, $58,

$58, $58, $58, $8B, $E8, $E9, $07, $B9, $FE, $FF, $00, $00, $00, $00, $00, $00);

//VC++6外衣 2

OEPCODEFIVE: THEAD =

($55, $8B, $EC, $6A, $FF, $68, $00, $00, $00, $00, $68, $00, $00, $00, $00, $64,

$A1, $00, $00, $00, $00, $50, $64, $89, $25, $00, $00, $00, $00, $83, $EC, $68,

$53, $56, $57, $58, $58, $58, $83, $C4, $68, $58, $67, $64, $A3, $00, $00, $58,

$58, $58, $58, $8B, $E8, $B8, $00, $10, $40, $00, $FF, $E0, $90, $00, $00, $00);

1.直接将入口地址赋给寄存器eax,然后jmp eax

0046902A B8 304A4500 mov eax,Project1.00454A30

0046902F FFE0 jmp eax

00469031 90 nop

2. 直接跳转到入口地址

00469124 - E9 07B9FEFF jmp Project1.00454A30

两种效果实际上是一样的,但我们为了方便修改花指令跳转到原来的入口地址，通常取得原

pe header的AddressOfEntryPoint,然后给寄存器eax保存改值，所以第二种方法就不太方便，

所以一般采用第一种方法，JMPOFF为花指令代码到跳转指令的偏移，如对Visual C++的花指令

JMPOFF=54,其后免跟的是原入口地址，可以随便填写，程序加花指令是会自动修改，一般可以

默认设为00104000(即00401000).

通过汇编修改花指令跳转原入口地址的语句:

asm //这里说明一下，这是嵌入的汇编代码,寄存器—CPU暂时储存数据的东西，比内存更快，以提高效率

PUSHAD

LEA eax, OEPCODE //将OEPCODE的地址交给寄存器

ADD eax, JMPOFF //添加JMPOFF值给寄存器

MOV edx, AddressOfEntryPoint //转移指令，相当于付值语句，左边给右边

MOV DWORD ptr [eax], edx //同上

POPAD

{Tstream中定义的虚方法有四个：

1、Read:此方法实现将数据从流中读出。函数原形为：

Function Read(var Buffer;Count:Longint):Longint;virtual;abstract;

参数Buffer为数据读出时放置的缓冲区，Count为需要读出的数据的字节数，该方法返回值为实际读出的字节数，它可以小于或等于Count中指定的值。

2、Write:此方法实现将数据写入流中。函数原形为：

Function Write(var Buffer;Count:Longint):Longint;virtual;abstract;

参数Buffer为将要写入流中的数据的缓冲区，Count为数据的长度字节数，该方法返回值为实际写入流中的字节数。

3、Seek:此方法实现流中读取指针的移动。函数原形为：

Function Seek(Offset:Longint;Origint:Word):Longint;virtual;abstract;

参数Offset为偏移字节数,参数Origint指出Offset的实际意义，其可能的取值如下：

soFromBeginning:Offset为移动后指针距离数据开始的位置。此时Offset必须大于或者等于零。

soFromCurrent:Offset为移动后指针与当前指针的相对位置。

soFromEnd:Offset为移动后指针距离数据结束的位置。此时Offset必须小于或者等于零。该方法返回值为移动后指针的位置。

4、Setsize:此方法实现改变数据的大小。函数原形为：

Function Setsize(NewSize:Longint);virtual; }

//将指针偏移量放到文件头部

fs.Seek(0, soFromBeginning);

//读取DOS头信息

fs.Read(DOSHEADER, sizeof(DOSHEADER));

//DOS MZ header 又命名为 IMAGE_DOS_HEADER.。其中只有两个域比较重要:

//e_magic 包含字符串"MZ"，e_lfanew 包含PE header在文件中的偏移量。

//将指针移到PE header在文件中的偏移量

fs.Seek(DOSHEADER._lfanew, soFromBeginning);

//读取PE header头信息

fs.Read(PEHEADER, sizeOf(PEHEADER));

//PEHEADER.FileHeader.NumberOfSections:文件的节数目。如果我们要在文件中增加或删除一个节，就需要修改这个值。

//将指针移到节表在当前位置的相对偏移量

fs.Seek(sizeOf(SectionHeader) *

(PEHEADER.FileHeader.NumberOfSections - 1), soFromCurrent);

//读取节表的信息

fs.Read(SectionHeader, sizeof(IMAGE_SECTION_HEADER));

//则本域值为0x400，表示本节是0x400字节长）。

//FileAlignment 文件中节对齐的粒度。例如，如果该值是(200h),，那么每节的起始地址必须是512的倍数。

//若第一节从文件偏移量200h开始且大小是10个字节，则下一节必定位于偏移量400h:

//即使偏移量512和1024之间还有很多空间没被使用/定义。

{PE装载器的工作:

1.读取 IMAGE_FILE_HEADER 的 NumberOfSections域，知道文件的节数目。

2.SizeOfHeaders 域值作为节表的文件偏移量，并以此定位节表。

3.遍历整个结构数组检查各成员值。

4.对于每个结构，我们读取PointerToRawData域值并定位到该文件偏移量。然后再读取SizeOfRawData域值来决定

映射内存的字节数。将VirtualAddress域值加上ImageBase域值等于节起始的虚拟地址。然后就准备把节映射进内存，

并根据Characteristics域值设置属性。

5.遍历整个数组，直至所有节都已处理完毕。

注意我们并没有使用节名: 这其实并不重要。}
