本文主要记录了如何通过一些列操作，将生成的keytab导入wireshark，实现可以在wireshark中直
接对Kerberos协议加密部分进行解密的一个过程，避免大家踩坑。
keytab是可以理解为一个密钥表，是key table的缩写，用途类似于用户的密码，keytab中包含一个
或多个条目，每个条目包含一个条目创建时的时间戳，主体名，密钥版本号，加密类型以及密钥本身。
具体关于keytab的信息可以上MIT的Kerberos实现网站上具体查看，这里只大概介绍。

我这10年的“搞站”路
我叫老牛，是高中室友给起的，原因很简单，我在8人寝室年龄排第六，四川话“老6”和“老牛”读音相仿。
后来我就把我的qq昵称改成了“L.N.”，我接受了这个称呼，因为自我审视，性格的确有执拗的一面，内
向且不善言谈。我以“老牛”的称呼警醒自己，大学就去参加了很多社团和当了2年团支书，得到了不错的
改善。扯远了，说回来，“L.N.”是我踏上“搞站”路的第一个代号，中途换过几个，发现还是L.N.
更“像”我，就这样一直用到现在。
第一次知道破解别人QQ空间密码是可以学习的，也是在高中。于是迫不及待的学习了一些如今看来都是
违法乱纪的技术手段，最后qq空间密码没破解开，倒是认识了很多技术上的好朋友，大家一起开开心心

智能合约安全开发

4. 常见漏洞
5. 常用工具
智能合约
智能合约（Smart Contract）是以太坊中最为重要的一个概念，即以计
算机程序的方式来缔结和运行各种合约。最早在上世纪 90 年代，Nick
Szabo 等人就提出过类似的概念，但一直依赖因为缺乏可靠执行智能合约的
环境，而被作为一种理论设计。区块链技术的出现，恰好补充了这一缺陷。
以太坊支持通过图灵完备的高级语言（包括 Solidity、Serpent、Viper）
等来开发智能合约。智能合约作为运行在以太坊虚拟机（Ethe... | pdf |

PE格式详解
概述
PE文件的全称为Portable Executable，是windows操作系统下可执行文件的一种文件格式，符合
COFF标准(Common Object File Format:https://en.wikipedia.org/wiki/COFF)，除了我们常见的exe文
件，像windows下的动态链接库文件(.dll)，内核驱动(.srv)，控制面板文件(.cpl)等都属于PE文件。
PE文件是一种数据结构，里面包含了OS加载程序能够把它加载到内存中并运行的所需的信息。
