各类文件的文件头尾总结
0x00 背景
近来处理webshell的时候，发现文件类型被篡改了，如何从HEX编码从判断是否为正常的文件，例如jpg是否为普通jpg还是合成了恶意代码的jpg，故需要分析文件头文件尾，进行一个简单的判断
0x01安装工具
相对来说，简单快捷的是安装notepad++,然后安装Hex-Editor插件。当前使用其他的，例如UltraEdit、winhex、IDA pro也是不错的选择。
notepad++下载地址：https://notepad-plus-plus.org/ 注意：请选择 Notepad++ Installer 32-bit x86，因为64位的软件无法直接安装Hex-Editor插件。
notepad++安装成功，选择【插件】- 【插件管理】，如下图
安装成功，重启notepad++即可。
