分析RSA算法的应用现状，论证文件加密应用RSA算法的可行性和意义。设计一套完整实用的RSA文件加密解决方案，具体编码实现。对RSA算法进行研究，从常规RSA算法出发，用C++实现RSA加密算法类库，并在32位windows平台封装成组件。在.Net平台引用此组件，实现可以对任意文件进行RSA加密 (Analysis of Application of RSA algorithm, file encryption application demonstration of the feasibility of RSA algorithm and significance. Design of a complete file encryption RSA practical solutions to achieve specific coding. Research on the RSA algorithm, starting from the conventional RSA algorithm using C++ class library to achieve RSA encryption algorithm, and in 32-bit windows platform components into a package. In. Net platform, referred to this component, the realization of arbitrary files on RSA encryption)

带密钥的md5算法库md5lib.h共有下列函数： char* MDString (char *) /*输入任意一个字符串，经过md5算法处理后，返回结果：一个定长（32个字符） 字符串 */ char* MDFile (char *) /*输入任意一个文件名，文件内容经过md5算法处理后，返回结果：一个定长 （32个字符）字符串 */ char* hmac_md5(char* text, char* key) /*输入任意一个字符串text,和一个用做密钥的字符串key,经过hmac_md5算法处 理，返回处理结果：一个定长字符串（32个字符）*/ 具体使用方法可参考例子sample.c,其运行结果在本文后面。-Md5 algorithm with a key repository md5lib.h total of the following functions: char* MDString (char*) /* enter any one string, after md5 algorithm processing, return the result: a fixed-length (32 characters) string*/char* MDFile (char*) /* enter any of the file name, file contents through the md5 algorithm processing, return the result: a fixed-length (32 characters) string*/char* hmac_md5 (char* text, char* key) /* input a string of arbitrary text, and a string key used as key, after hmac_md5 algorithm processing, return processing results: a fixed-length string (32 characters)*/specific examples of the use of methods can be found sample.c, the results

今天我们学习了des对称加密算法这是一个des算法的C++实现-This is a des !

这是反汇编驱动程序的源代码这是反汇编程序的源代码-This is the anti-driven compilation of a program"s source code that is anti-assembler source code

EXE二合一源代码!不用多说了!用tasm编译!-source code! Needless to say! With Tasm compiler!

数据隐藏程序，比机密更安全-Data Hiding procedures, more than security secrets

取代式密码的存在，已经超过2500年 以上，最早利 用的范例 是在西元600年 左右，内容是以颠倒的希伯來 文构成的。凯萨大帝（Julius Caesar）也曾经使用称为Caesar密码法。方法为将每个字母用其后的第三个字母來 取代。(Replace passwords existence, has more than 2,500 years or more, the first example is using a range of about the year 600 AD, the contents of the text is upside-down Heber future composition. Great Caesar (Julius Caesar) has also been known as the Caesar cipher using the method. Method is used then each letter is replaced by the third letter.)
