压缩与解压缩类；压缩文件至.zip包内，增加文件至.zip包内，及解压缩相关操作。(zip and unzip。)

文件加密使用,可以实现对PC上文件进行加密解密功能(document encryption use, the PC can be achieved on the document encryption and decryption functions)

RSA公钥加密程序，可实现密钥对生成，加解密任意字符串功能。MFC界面。(RSA public key encryption program, enabling the key pair generation, encryption and decryption functions of arbitrary strings. MFC interface.)

输入： 输入包括多个测试集，每行为一个正奇数N(1 <= N < 10)， 0作为输入的结束且不需要处理。 输出： 对于输入的每一个N， 输出一个它所对应的N阶幻方，如果存在多个， 任意一个即可。 Sample Input 1 3 0 Sample Output 1 4 9 2 3 5 7 8 1 6 (Input: The input includes multiple test sets, each one being the odd behavior of N (1 < = N < 10), 0 as the end of the input and does not require treatment. Output: For each input N, N it corresponds to the output of a magic square, if there is more than one, any one can. Sample Input 1 3 0 Sample Output 1 4 9 2 3 5 7 8 1 6)

条件语句语法分析及语义分析程序设计,LR法输出逆波兰表达式(Conditional statements grammar analysis and semantic analysis of program design, LR law output Reverse Polish expression)

这是lzw算法源程序代码，纯c语言编程实现，希望对您有用。(lzw algorithm source code, pure c programming language, and I hope to you useful.)

DVB 加扰软件，对TS流文件进行加扰，符合DVB标准(it s a dvb scramble software . it can scrambling ts stream file ,which apply for dvb standards)

通过调用openssl库进行aes加密，本程序已编译好了openssl，无需在进行编译！生成时请引用lib文件(By calling the openssl library aes encryption, the program has compiled the openssl, without making compilation! Please cite lib files generated)

1、 所有密钥的装载与导出都采用密文方式； 2、 密钥管理系统采用3DES加密算法，采用根密钥生成系统、主密钥生成系统、初始化卡生成系统、密钥注入系统四级管理体制； 3、 在充分保证密钥安全的基础上，支持IC卡密钥的生成、注入、导出、备份、更新、服务等功能，实现密钥的安全管理； (1, the loading and export all keys are in cipher text 2, the key management system uses the 3DES encryption algorithm, using the root key generation system, the master key generation system, initialize the card generation system, key injection system four management systems 3, the key to ensure full security, based on the support of the IC card key generation, injection, export, backup, update, and service functions to achieve key security management )
