Encrypt-of-ConnectionString

加密和解密app.config或web.config的连接字符串(Encrypt and Decrypt of ConnectionString in app_config and-or web_config)

凯撒和维吉尼亚加密方法，两种算法都不是很复杂，基本原理也相似所以都写入一个文件中来表示。-Caesar and Virginia encryption method, two algorithms are not very complicated, so the basic principles are also similar to a document written to express.

笔者长期从事移动通信系统的无线链路调制与解调、物理层实现方面的工作。在移动通信GSM系统中，我们进行语音或者业务信道解调时，都会遇到CRC的求解。通常在硬件DSP实现时，特别是40位CRC求解时候，由于生成多项式有41项，DSP最大一次能处理40位，所以使用单个寄存器会遇到一些困难，那么以下这个程序将会解决这一困难（这是针对定点DSP、C55xx的编程实现方法）。-The author has long been engaged in mobile communication system modulation and demodulation of wireless links, the physical layer to achieve work. GSM in the mobile communications system, we have a voice or channel demodulation operations, it will encounter the solution of CRC. DSP hardware usually realize, especially when solving the 40 CRC, as the generation polynomial has 41, DSP can handle the largest 40, so using a single register may encounter some difficulties, then following this process will solve this One difficulty (which is for fixed-point DSP, C55xx realize programming methods).

A simple cpp program, that receives a file, does a bit-wise "not" for every character, and adds "not" to the extension. Repeated running does the same and removes the "not" from extension. This a "pseudo-encryption", but very useful to avoid automated filtering software. This way it is possible to send "exe" files (or anything else) without the emails being blocked... First - send the source code, have your (enlightened) recipient compile it, then send the "notted" file. The code is not very efficient though, I only had 30 minutes to invest... :)-A simple cpp program, that receives a file, does a bit-wise "not" for every character, and adds "not" to the extension.

修正了原CMd5类的CaculateStr函数的严重错误，并且转到新的C++类库。此类已经经过验证，文件和字符串均能得到正确结果，支持Unicode（Unicode时不需要转换）-amendment of the original CMd5 CaculateStr function of the type of serious errors and to the new C Class. Such has been validated, documents, and the string to get the correct result, Unicode support (Unicode does not need conversion)

（1）为班级学生花名册建立开桶或闭桶散列表。 （2）友好性：界面要友好，输入有提示，尽量展示人性化。 （3）可读性：源程序代码清晰、有层次。 （4）健壮性：对输入的数据有纠错处理。((1) class roster for the establishment of open or closed barrels barrels hash table. (2) friendly: the interface should be friendly, to bring in people with tips, try to show humanity. (3) readability: source code clear, there are levels. (4) robustness: the input data are error-correcting processing.)
