Description: des加解密核心代码
对称密钥加密算法DES是由IBM公司在70年代发展起来的，并经政府的加密标准筛选后，于1976年11月被美国政府采用，DES随后被美国国家标准局和美国国家标准协会ANSI承认。
DES使用56位密钥对64位的数据块进行加密，并对64位的数据块进行16轮编码。与每轮编码时，一个48位的"每轮"密钥值由56位的完整密钥得出来。
-des encryption and decryption code core symmetric key encryption algorithms DES by IBM in the 1970s with the development of to, and after a government encryption standard screening, in November 1976 by the United States government to adopt, DES followed by the United States National Bureau of Standards and the American National Standards Institute ANSI recognition. DES use 56 to 64 key pieces of data encryption, as well as 64 pieces of data for 16 coding. Coding with each round, a 48 "round" key values from the full 56 key works.

Description: VC++实现DES加解密
Tips:
1.本程序可以加密1-4096个字符的任意长度字符串
2.如果密钥长度过短或者为空,程序将使用默认
密钥"YinXueYuan Build It!"进行加密.
3.加密结果将用16进制字符显示
4.本加密程序同时支持中/英文字符(包括密钥和明
文)
5.本加密程序支持特殊字符[例如换行符(回车键)]
Attention:
1.加密时,密文的最后一个字符请不要使用半角
美元符号 $
2.字符串加密最多支持加密4096个英文字符(解密
最多为8192个十六进制字符),
如果需要加密的内容过多,请使用文件加密
3.为了保证您的数据安全,建议不要使用默认密
钥,并保持您的密钥在八位以上
4.由于时间关系,文件加密功能尚未完成,请谅解.
5.DES已经被证明不安全,建议您修改本程序源
码,将其改为3DES

Description: DES的每个分组是64位，既明文和密钥都是64位（密钥实际用56位，每字节第8位为校验）。这个算法的核心是Feistel密码，由于其设计的巧妙，加密解密都用一个函数，具体原理请查阅其他资料。DES的流程基本是执行16轮下面的运算：-DES each packet is 64, both explicit and are 64-bit key (actual key 56, the first 8 bytes each for validation). The core of this algorithm are Feistel password, because of its ingenious design, encryption and decryption using a function, specifically the principle of access to other information requested. DES is the implementation of the basic flow of 16 the following operations:
