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.

题目:某个公司采用公用电话传递数据,数据是四位的整数,在传递过程中是加密的,加密规则如下:
每位数字都加上5,然后用和除以10的余数代替该数字,再将第一位和第四位交换,第二位和第三位交换。
1.程序分析:
2.程序源代码:(Topic: a company USES the public telephone relay data, data is four integers, in the relay in the process is encrypted, encryption rules are as follows:
Each Numbers add 5, then use and divided by the number of 10 instead of a remnant, then the first and fourth exchange, the second and third exchange.
1. The program analysis:
2. The source code:)

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 :
