代码说明：

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。虽然56位密钥的DES算法已经风光不在,而且常有用Des加密的明文被破译的报道,但是了解一下昔日美国的标准加密算法总是有益的,而且目前DES算法得到了广泛的应用,在某些场合,她仍然发挥着余热.（如：UNIX的密码算法就是以DES算法为基础的）。将其修改为三重DES也能抵抗破解。下面是关于如何实现DES算法的语言性描述：(DES ( Data Encryption Standard ) algorithm, in 1977 the U.S. government s official permission , is a 56 -bit key to encrypt 64 data . 56 keys of the DES algorithm scenery is not , and often with Des encryption expressly decipher reported , but look at the old standard encryption algorithm is always useful , but the DES algorithm has been widely used in a some occasions , she still plays a waste heat . (such as : UNIX password algorithm is DES algorithm -based ) . To modify the Triple DES is also resistant to cracking . The following is a description language on how to achieve the DES algorithm : )

一个周期3的多表代替密码，第1个表由密钥字法产生（密钥字自拟），第2个表由洗牌法产生（注意，字母a~z与数字0~25一一对应），第三个表由公式法产生（数学公式自拟，注意它须是Z26上的一个一一变换）(a cycle of three multi-table instead of passwords, a table by key word method, (key word from the intended), Table No. 2 produced by shuffling method (note, a letter with a number of z ~ 0 ~ 25 he gathers), 3rd tables generated by the formula (from the proposed mathematical formula, it should pay attention to the Z26 is a transformation on January 1))

本程序可以在 PE 文件的结尾增加一个新节，从而在已被“加密”的程序开始运行时，要求输入密码。(This procedure can be the end of the document in the PE to add a new section, which has been in the encryption process to start running when asked to enter a password.)

DESEncryptionDecrypt
编写的DES 对称加解密技术，可随时进行明文密文之间的转换，有需要的朋友可以下载测试！本人目的打算对后台数据库的敏感信息字段用该方法加密，然后用软件权限控制读取，这样即使直接SQL后台取数，也得不到明文数据。(Write DES symmetrical encryption technology, may at any time for conversion between plaintext cipher, friends in need can be download test! I purpose going to the backstage database of sensitive information field with the method of encryption, and then use software to read access control, so even if the SQL backend access directly, also can not get clear data. )

修改本程序中的U盘的序列号后，程序可以变成你自己的独立的Ｕ盘启动密匙，　只能你的Ｕ盘才能打开程序　不需要往Ｕ盘中存入任何文件，就可实现用Ｕ盘加密程序.只能通过你的U盘启动你的程序程序中有详细的注释(Encrypt your program by a soul U-disk without saving anything in you disk Modify the program, U-disk serial number, the program can become your own independent U disk key, only you can open U disk U disk does not need to deposit any file, can be achieved U disk encryption program)
