Description: 文件夹加密工具(开源代码)
软件作者：dyforc
发现文件夹加密的软件较少，而且都不大适合我用，所以写了一个。主要是对指定文件夹和其子目录下所有文件加密。
用到的加密算发是RC4。
本程序特色：
1. 可以指定加密长度（即只对文件的一部分进行加密），（对大文件加密很有用）
2. 可以随机生成动态密钥
（即使加密目录下某个文件的加密密钥被破解了，不影响目录下其他加密过的文件，因为每个文件加密密钥不同，都由输入的密钥随机计算产生）
3. 可以随机化文件名，对文件生成MD5，以此来保障解密成功。
4. 加解密过程中程序允许执行指定脚本。-Folder encryption tool (open source code)
Software Author: dyforc
Found the software folder encryption less, but I do not fit, so to write one. Is the designated folder and all its subdirectories file encryption.
Calculation made use of encryption is RC4.
This procedure features:
1. Can specify the encryption length (that is, only part of the document encryption), (large file encryption useful)
2. Can be randomly generated dynamic key
(Even if encrypted a file directory of the encryption key being cracked, the directory does not affect other encrypted files, because a different encryption key for each document, by the calculation of input generate a random key)
3. Of file name can be random, the document to generate MD5, in order to protect the successful decryption.
4. The process of encryption and decryption process to allow the implementation of the specified script.

Description: 用NS- 2 仿真各种路由协议性能时用到的传统运动场景发生器存在两个缺陷: 运动状态不能迅速过渡到稳态, 节点速度的
均匀分布区间起始值只能为0。为了弥补上述缺陷, Tracy Camp 研制了稳态运动场景发生器。通过仿真验证了采用该发生器可大
大缩短仿真时间, 在此基础上仿真AODV 和DSDV 两种路由协议, 首次从吞吐量、协议包开销、平均延迟三个方面对稳态运动场景
下的两种路由协议性能进行分析, 得出结论表明采用稳态运动场景进行路由协议仿真是非常必要的。
关键词: 稳态运动场景 setdest 更新过程 Random Waypoint-Abstr act: As a module of NS2, the traditional movement scenario generator, when simulating routing protocol, has two limitations.
One is that the transition time of stable status is long, and the other is that the uniform- distributing low bound of node speed is
only zero.To remedy these faults, Tracy Camp has developed a stable movement scenario generator.The simulation proves that
simulation time can be reduced largely by using this generator.Based on this result, a simulation for AODV and DSDV routing
protocol is implemented.Then the performance of two protocols is analyzed on three aspects: throughput, routing overhead packets,
average delay.At last the conclusion is drawn, which shows it is essential to adopt stable movement for simulation of routing
protocols.
Key words: stable movement scenario setdest renewal process Random Waypoint

Description: 写了一个文件加解密工具（VC9+OPENSSL）
CA程序：
生成2个RSA密钥对，分别保存为PEM格式，密码保护私钥，文件名为“RSAPrivateKey.pem”和“RSAPublicKey.pem”。
加密：
将指定明文文件加密，密文件格式自已定义，要求文件内容用对称算法（3des）加密，对称密钥（KEY）为随机生成，随机密钥用“RSAPrivateKey.pem”的公钥加密后，存放在密文文件头内（KEY1）；对明文文件做摘要计算（HASH），将计算结果用“RSAPublicKey.pem”的私钥加密后（SIGN），放到密文文件头内；文件头内有明文的原始长度信息。
解密:
将密文文件解密成明文文件，流程与加密相反，先用“RSAPrivateKey.pem”私钥解密（KEY1）数据，得出随机密钥（KEY）；用随机密钥对密文解密，得到明文文件；对明文文件进行摘要计算，得出HASH1；用“RSAPublicKey.pem”公钥解密SIGN，得出HASH2；HASH1与HASH2做对比，相同表示解密成功，不同表示解密失败。
密文文件头内可以保存原始加密人的信息以及解密人的信息，这样可以快速判断解密者是否有权限解密该密文文件，如果有权限则进行解密过程，否则直接提示没有权限解密。
