PE文件格式分析心得

PE文件格式分析心得2008-01-05PE文件格式最近好像炒得沸沸扬扬，由于我正在做一个这样的程序，索性将自己的心得写出来与大家同享。

PE文件头分两大部分：

1：DOS ‘MZ’ HEADER

2：IMAGE_NT_HEADERS

其中IMAGE_NT_HEADERS中包含

PE signature

IMAGE_FILE_HEADER

IMAGE_OPTIONAL_HEADER（其中包含Data Direcotry）

文件头后紧跟着为

Section Table （array of IMAGE_SECTION_HEADERs）

在DELPHI的windows.pad中已经有定义的有：

TImageDosHeader;

TImageNtHeaders;

TImageSectionHeader; { size of TIm..der is $28 }

定义变量后按住Ctrl可以察看具体的项目，这里我就不多说了，这方面的东西也很多。

而其他的如TImageResourceDirectory等，在DELPHI中却没有定义，察看其他资料，我在这里给出他们的结构和简单说明：

以下是我写的PEDump.exe的类型说明：

type
  PIMAGE_RESOURCE_DIRECTORY = ^TImageResourceDirectory;
  _IMAGE_RESOURCE_DIRECTORY = packed record
   Characteristics:DWORD;
   TimeDateStamp:DWORD;
   MajorVersion:WORD;
   MinorVersion:WORD;
   NumberOfNamedEntries:WORD;
   NumberOfIdEntries:WORD;
  end;
  TImageResourceDirectory = _IMAGE_RESOURCE_DIRECTORY;
  { 资源目录的格式说明 }
  PIMAGE_RESOURCE_DIRECTORY_ENTRY = ^TImageResourceDirectoryEntry;
  _IMAGE_RESOURCE_DIRECTORY_ENTRY = packed record
   Name:DWORD;     { NameOffset:31,NameIsString:1 }
//  Id:WORD;
   OffsetToData:DWORD; { OffsetToDirectory:31,DataIsDirectory:1 }
  end;
  TImageResourceDirectoryEntry = _IMAGE_RESOURCE_DIRECTORY_ENTRY;
  { 资源目录进入点的格式说明 }
  PIMAGE_RESOURCE_DIRECTORY_STRING = ^TImageResourceDirectoryString;
  _IMAGE_RESOURCE_DIRECTORY_STRING = packed record
   Length:WORD;
   NameString:CHAR;
  end;
  TImageResourceDirectoryString = _IMAGE_RESOURCE_DIRECTORY_STRING;
  { 资源目录名的格式说明 }
  PIMAGE_RESOURCE_DIR_STRING_U = ^TImageResourceDirStringU;
  _IMAGE_RESOURCE_DIR_STRING_U = packed record
   Length:WORD;
   NameString:WCHAR;
  end;
  TImageResourceDirStringU = _IMAGE_RESOURCE_DIR_STRING_U;
  { unicode形式的资源目录名的格式说明 }
  PIMAGE_RESOURCE_DATA_ENTRY = ^TImageResourceDataEntry;
  _IMAGE_RESOURCE_DATA_ENTRY = packed record
   OffsetToData:DWORD;
   Size:DWORD;
   CodePage:DWORD;
   Reserved:DWORD;
  end;
  TImageResourceDataEntry = _IMAGE_RESOURCE_DATA_ENTRY;
  { 资源目录数据进入点的格式说明 }
const
  IMAGE_RESOURCE_NAME_IS_STRING = $80000000;
  { 检测TImageResourceDirectoryEntry.Name的最高为是否设立，
   是则说明剩下的31位指向IMAGE_RESOURCE_DIR_STRING_U的偏移，
   否则说明剩下的31位为一个整数ID。 }
  IMAGE_RESOURCE_DATA_IS_DIRECTORY = $80000000;
  { 检测TImageResourceDirectoryEntry.OffsetToData的最高为是否设立，
   是则说明剩下的31位指向另一个IMAGE_RESOURCE_DIRECTORY的偏移，
   否则说明剩下的31位指向IMAGE_RESOURCE_DATA_ENTRY的偏移。 }
