基于哈弗曼树的压缩软件，可压缩文字和位图。(Huffman tree based compression software, compressible text and bitmaps.)

说明：  idea算法VC++源码，包含系列文件 idea.h idea.cpp ideadlg.h ideadlg.cpp resource.h stdafx.h stdafx.c(idea algorithm VC++ source, including the series of documents idea.hidea.cppideadlg.hideadlg.cppresource.hstdafx.hstdafx.c)

do-while循环语句的LR分析，包括文法的建立，文法的LR分析表，词法分析，LR分析过程，输出三地址表示形式。(do-while loop statement LR analysis, including the establishment of grammar, grammar analysis of the LR tables, lexical analysis, LR analysis process, the output three-address representation.)

检测CRC编码 看CRC编码在传输后是否有错误 有变动 (Detection CRC codes to see whether the CRC coding errors in the transmission there is a change)

编译原理课程设计,包括词法分析，语法分析，目标代码优化的编译器,希望大家提出意见(compiler theory of curriculum design, including lexical analysis, grammar analysis, the objectives of optimizing code compiler, we hope that the views)

信息安全的RSA与DES加解密算法的实现，用的是Visual C++MFC(Information Security RSA encryption and decryption with the DES algorithm, using the Visual C++ MFC)

椭圆曲线的实现(ECC)，椭圆曲线算法是代数几何、数论等多个数学分支的一个交叉点，一直被人们认为是纯理论学科。而椭圆曲线密码体制，是基于椭圆曲线离散对数问题的一种公钥密码体制(Realization of elliptic curves (ECC), elliptic curve algorithm is algebraic geometry, a number of mathematical intersection of number theory and other branches, has been considered a purely theoretical discipline. The elliptic curve cryptosystem is based on elliptic curve discrete logarithm problem as a public-key cryptosystem)

AES加解密C语言源代码，可直接运行通过，方便大家借鉴学习(AES encryption and decryption of C language source code, can be directly run by, we facilitate learning from)

此源码是编译原理中对“递归下降法的语法分析器“的设计(This principle is to compile the source code for " recursive descent parser" design)

MD5加密算法，可以加密包含二进制数据的数据块，生成16字节MD5加密数据。(MD5 encryption algorithm to encrypt data blocks that contain binary data, generates a 16-byte MD5 encrypted data.)
