DES( Data Encryption Standard)算法，于1977年得到美国政府的正式许可，是一种用56位密钥来加密64位数据的方法。DES算法以被应用于许多需要安全加密的场合。（如：UNIX的密码算法就是以DES算法为基础的）。-DES (Data Encryption Standard) algorithm, in 1977 the United States government"s official permission, is a key 56 to 64-bit data encryption methods. DES algorithm to be applied to many needs security encryption occasions. (Eg : UNIX password algorithm is to DES algorithm-based).

Vigenere 体制 本程序使用dev c++开发实现，希望对大家有用.-Vigenere institutional procedures for the use of the dev c achieve development, we hope that the right useful.

delphi版本的各种加密方式 DES AES MD5 BASE64 SHA，有各种例子

对于这个问题的实现、刚刚给过一个程序，突然想起另外一种简单一些的方法，一并给出[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）。]： -For the realization of this issue, just to have a program, suddenly reminded of another simpler way to be given [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). ]:

S-DES编程S-DES加密采用8和10明文作为密钥输入，有8个密文作为输出。使用同一密钥进行加密和解密。要求：CBC模式到解密版本增加。对话界面：在目录选项中选择加密或解密密钥输入明文或密文文档（对于二进制内容，。Txt文件，），建议加密或解密已完成2。输出：产生密文或明文文本3。提供：文档、源代码、可执行文件，通过加密实验得到运行结果。4分析雪崩效应文件：键下同一个显式改变文本在闭合处的差异，在同一个地方显式改变电位器在密文处的情况

一个用移位思想实现的简单数据加密程序，因为不论是大写还是小写字母,其ASC码值都是按顺序排列的.故可以用相对应的ASC码值进行判断以及算法实现.-a shift ideology with a simple data encryption procedures, because both uppercase or lowercase letters, the value of ASC codes are arranged in chronological order according to the. It can be used to be the relative value of ASC code of judgment and algorithm.
