Description: 维吉尼亚（Vigenere）密码为了提高密码的破译的难度，人们有发明一种多表置换的密码，即一个明文字母可以表示为多个密文字母，多表密码加密算法结果将使得对单表置换用的简单频率分析方法失效，其中维吉尼亚密码就是一种典型的加密方法。维吉尼亚密码是使用一个词组（语句）作为密钥，词组中每一个字母都作为移位替换密码密钥确定一个替换表，维吉尼亚密码循环的使用每一个替换表完成明文字母到密文字母的变换，最后所得到的密文字母序列即为加密得到的密文，具体过程如下： 设密钥 ，明文 ， 加密变换 其中 例如，M＝data security，k＝best。可以先将M分解为长为4的序列data secu rity 每一节利用密钥k＝best加密得密文c=Ek(M)=EELT TIUN SMLR。 当密钥k取的词组很长时，截获者就很难将密文破解。（我们还在计算机上就维吉尼亚密码设计的方法，编写了一个小的程序，可以运用其进行加密和相应的解密。见附录） 由于我们知识和条件所限，本学期对以上6种古典加密方法进行了学习和研究，从中我们收获颇多，我们了解古典密码学的基本原理和方法，并能够对信息进行简单的加密和解密，大大提高我们的学习文化知识的兴趣和热情，如果有条件我们在今后将进一步研究密码学。-Virginia (Vigenere) password to the password to raise the difficulty deciphering, people have invented a multi-table replacement passwords, or express a letter can be expressed as a number of secret alphabet, multi-table password encryption algorithm results will enable replacement of single table with a simple frequency analysis method failure, which Vij Caledonia is a typical password encryption methods. Virginia is the use of a password phrase (statement) as a key, every phrase has a letter as a replacement shift key password table to determine a replacement, Virginia passwords for each cycle of replacement of a complete table of explicit letters of the alphabet secret transform, get in the end secret alphabet sequence namely the encrypted ciphertext, the specific process is as follows

Description: 这是我想到的一个非常有用的小程序，顾名思义，这个程序就是把不同的信号（如不同的文件：文本，图片，语音，乃至视频...）储存入电脑的图片文件.BMP文件中，以达到节省空间，安全加密，数据保护，多媒体同时运行，提高空间与时间的并行性。
-I think this is a very useful small program, as the name suggests, the procedure is different signals (such as different files : text, images, voice and even video ...) storage computer image files.

Description: des算法简单实现。它以64位的明文和56位的密钥作为输入，通过DES加密运算产生64位密文输出。其解密过程利用同以密钥和算法将密文还原成明文。因为java语言的安全性＆网络处理能力强，所以就利用了java语言编写-des simple algorithm to achieve. It's expressly 64 and 56 as the key input, through DES encryption algorithms have 64 ciphertext output. Its use decryption process with a key and cipher algorithm reduced explicitly.

Description: 说明：
1、里面有什么：
1.1、org.bouncycastle.*下的所有软件是bouncycastle组织开发的软件包
1.2、org.infosecurity.*下的软件包括：
DES_CBC算法的实现
RSA算法的实现（包括：密钥生成、公钥加密和私钥解密、数字签名及签名验证）
数字信封的实现
利用数字信封实现大文件的加密、解密。
2、有什么用：
2.1 研究、学习信息安全中的密码学设计与实现技术。
2.2 当然如果大家觉得在其它地方用的上，我会觉得很高兴的。
3、还有什么改进：
3.1 对文件加密、解密的时候要频繁的IO，如果加一个缓冲区，比如10K、50K等，
只有缓冲区满了才写入DISK这样将提高效率。
3.2 RSA私钥积存的时候可以按PKCS8形式，再经BASE64编码保存比较好。-Note : 1, mean there : 1.1, org.bouncycastle .* of all software development organizations is bouncycastle package 1.2, org.infosecurity .* The software includes : DES_CBC algorithm to achieve the realization of the RSA algorithm (including : key generation, public key and private key encryption decryption, digital signatures and signature verification), the realization of digital envelope using digital envelope realize document encryption, decryption. Two, what is the use of : 2.1, learning the information security cryptography design and technology. 2.2 Of course, if you think in the other parts, I feel very happy. Three, what is there for improvement : 3.1 pairs of file encryption, decryption, and the time to frequent the IO, plus a buffer, such as 10K, 50K, the only buffer is needed for

Description: ASP.NET开发技术详解源代码
将解决方案目录“\简历管理系统\hrmanage”拷贝到本机中，并设置目录hrmanage目录的虚拟目录名称为hrmanage。双击根目录hrmanage.sln解决方案文件，系统会自动调用Visual Studio .NET打开本解决方案，通过“解决方案资源管理器”可查看到各层类文件的实现代码。
如果设置Webs目录的虚拟目录名称不是hrmanage，则需要修改Webs目录下的Webs.csproj.webinfo文件，用记事本或其他文本编辑器打开，可以看到如下的设置：
<VisualStudioUNCWeb>
<Web URLPath = "http://localhost/hotop100/Webs.csproj" />
</VisualStudioUNCWeb>
修改路径为设置的虚拟路径即可。
此外，还需要修改数据库连接字符串，用记事本或其他文本编辑工具打开hrmanage目录下的Web.config文件，找到<appSetting>节点，如下所示：
<appSettings>
<!--此处设置数据库连接字符串-->
<add key="ConnectString" value="data source=localhost initial catalog=msrcn persist security info=False user id=sa pwd=hello workstation id=msrcn packet size=4096"/>
</appSettings>
