实现移位密码（扩展凯撒密码），用键盘接收明文和密钥，屏幕打印密文。-Achieve translocation password (Extension Caesar password), use the keyboard to receive explicit and key, screen printing ciphertext.

大整数运算的实现-large integer arithmetic Implementation

程序使用C++展示相当强的XOR加密。 当它unencrypting文件时，包括EOF验错和自动侦查。程序很好被提供并且做在串类建立的好用法。-Program Uses C++ to Demonstrate A Fairly Strong XOR Encryption. Includes EOF error checking and automatic detection of when it is unencrypting a file. Program Is Documented Well And Also Makes Good Use of the Built In String Class.

简单的密码例子，让密码储存在程序中 简单的密码例子，让密码储存在程序中-simple code example, passwords stored in the process simple code example, the password stored procedures

IDEA加密算法属于数据块加密算法(Block Cipher)类。IDEA使用长度为128bit的密钥，数据块大小为64bit。-IDEA encryption algorithm is data block encryption algorithm (Cipher Block) category. IDEA use of the length of the 128 bit key, the data block size for 64bit.

用VC做的一个画直线和曲线的程序。-VC do a painting line and curve procedure.

一个DES加密算法的实现-a DES encryption algorithm implementation

数据加密用C#做的加密程序,望各位多提问题-data encryption using C# do encryption, and hopes to raise the issue

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).
