Description: DES算法要求加密密钥和解密密钥一致。密钥所需的字节数祖长度为8位。基于对需求的理解，密钥由客户设定，在加密和解密的时候，在服务器端输入一密钥达到文件的加密需求，在终端输入同一密钥达到加密文件的解密需求。
DES加密的时候，最后一位长度不足64的，它会自动填补到64，那么在我们进行字节数组到字串的转化过程中，可以把它填补的不可见字符改变了，所以时常引发系统抛出异常。为此，在处理过程中，我们需要把一些信息编码保存起来，使之保证数据完整性。故在des.Des类中运用到了convert4CharTo64bit方法。

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:

Description: DES工作的基本原理是，其入口参数有三个:key、data、mode。 key为加密解密使用的密钥，data为加密解密的数据，mode为其工作模式。当模式为加密模式时，明文按照64位进行分组，形成明文组，key用于对数据加密，当模式为解密模式时，key用于对数据解密。实际运用中，密钥只用到了64位中的56位，这样才具有高的安全性。
-The basic principle of DES is that its entrance there are three parameters: key, data, mode. key used for encryption and decryption keys, data encryption and decryption for the data, mode of its work. When the model for the encryption mode, expressly in accordance with the grouping 64 to form a specific group, key for data encryption, when the model mode for decryption, key for decryption of data. Practical application, the key has been used only 64 of 56, so that with high security.

Description: des加密算法的实现，DES算法为密码体制中的对称密码体制，又被成为美国数据加密标准，是1972年美国IBM公司研制的对称密码体制加密算法。其密钥长度为56位，明文按64位进行分组，将分组后的明文组和56位的密钥按位替代或交换的方法形成密文组的加密方法。DES加密算法特点：分组比较短、密钥太短、密码生命周期短、运算速度较慢。(The symmetric cryptosystem in the DES algorithm for the password system, has been became the data encryption standard, was developed by the United States in 1972 IBM symmetric cryptosystem encryption algorithm. Its key length is 56, expressly groups, according to a 64 - bit will clear after the grouping and 56 set of keys according to a replacement or exchange method to form cipher group encryption method)
