Description: 除了上面提到的压缩方法，你也可以调用VB的工具MakeCab.exe（在VB5\\setupkit\\kitfil32或VB98\\Wizards\\PDWizard目录下）生成.cab文件。先构造一个Directive 文件(*.ddf)，然后使用Shell命令调用MakeCAB /f excel.ddf就可以生成*.cab文件。关于Directive 文件的格式，可以参考MSDN Library中的《MakeCAB: A Compression and Disk Layout Tool》一文。 -addition to the above-mentioned methods of compression, you can call VB Tools MakeCab.exe (VB5 \\ setupkit \\ kitfil32 or VB98 \\ Wizards \\ PDWizard directory) production. Cab document. First constructed a Directive document (*. DDF), then use the Shell order call MakeCAB / f excel.ddf can generate *. cab documents.

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。
-To write a file encryption and decryption tool (VC9+ OPENSSL)
CA procedures:
Generates two RSA key pairs, respectively, save for the PEM format, password-protected private key, the file named "RSAPrivateKey.pem" and "RSAPublicKey.pem".
Encryption:
The specified plaintext file encryption, secret self-definition file formats require the document to use symmetric algorithms (3des) encryption, symmetric key (KEY) is randomly generated, random key to use "RSAPrivateKey.pem" public key encryption, stored in the ciphertext header inside (KEY1) summary of the calculation of the plaintext file to do (HASH), the calculation results with the "RSAPublicKey.pem" private key encryption (SIGN), into ciphertext in the file header file header if there is express The original length of the message.
Decryption:
Decrypt the ciphertext into a plaintext file documents, processes and encrypt the contrary, the first to use "RSAPrivateKey.pem" decrypt the private key (KEY1) data, derived random k

Description: DES加密聊天工具，共包含3个文件：chat.cpp、des.h、makefile。
编译：命令行模式下，切换到代码所在目录，输入make后回车即可。
运行：命令行模式下输入 ./chat，然后选择程序执行角色（客户端或服务器）。如选择服务器，则程序自动打开端口开始监听；如选择客户端，则需要输入服务器地址。最后输入命令quit退出程序。-DES encrypted chat tool, contains a total of 3 files: chat.cpp, des.h, makefile. Compile: Command line mode, switch to the code directory, type make after the press Enter. Run: command line, type./Chat, and then select the program execution role (client or server). If you choose the server, the program automatically opens the port to start listening If you choose a client, you need to enter the server address. Finally, enter the command quit to exit the program.

Description: DES通用加密方法。首先，创建一个该工具类对象：如
DES des = new DES(key),其中key为位数大于8的密钥
其次，对原始信息data进行加密，直接调用encrypt方法，得到加密后的字符串，如
String encryptResult = des.encrypt(data) //得到加密后的数据字符串
最后，对加密后的字符串encryptResult解密，直接调用decrypt方法，可得到与原始数据data一致的字符串，如
String decryptResult = des.decrypt(encryptResult) //得到解密后的数据字符串
解密后的字符串decryptResult，与原始信息data一致。-General DES encryption method. First, create a class object of the tool: If DES des = new DES (key), where key is the key followed by more than 8 bits, the original information data is encrypted, encrypt method called directly to get the encrypted string such as String encryptResult = des.encrypt (data) // get the encrypted data string last, to decrypt the encrypted string encryptResult direct call decrypt method, available data consistent with the original data string, such as String decryptResult = des.decrypt (encryptResult) // get the decrypted data string decrypted string decryptResult, consistent with the original information data.
