自定义的加密压缩和解压

零数据加密算法（数据加密算法，DEA）是对称加密算法，可能是最广泛使用的密钥系统，特别是在金融数据的安全性，最初开发的DEA是嵌入在硬件中。一般情况下，ATM（自动取款机，ATM）使用DEA。它出自IBM的研究工作，IBM有它的专利数年，但1983年以后已经过期，在公共范围，允许在特定条件和使用情况下免除专利使用费。 1997年正式通过了美国政府。DES原来的思路可以参考一下二战中德国的Enigma机，大约相同的基本思想。传统的密码加密都是由古代的观念，从循环移位，谜机器是基于扩散模糊。但原则的本质是相同的。现代DES在二进制级别做着同样的事：替代模糊，增加了分析的难度

我的项目主题是防止篡改问题纸使用视觉密码。 防篡改问题纸 （新） 提供了一个非常安全的方法来隐藏文件在不同股票的问题。在此应用中，试卷的题目分解成 n 件，单独地产量没有关于试卷的题目的信息。问题，这些纸片被称为股票或阴影，然后可能分布在一组 n 参与者/经销商。通过结合任何 k 问题纸可以恢复这些股票，但结合小于 k 的他们不会透露任何信息关于问题的论文。在此方法中， 重建的问题本文基于 XOR 运算。这将启用一个回获得完

希尔排序算法: 基本思想：将整个无序序列分割成若干小的子序列分别进行插入排序。 序列分割方法：将相隔某个增量h的元素构成一个子序列。在排序过程中，逐次减小这个增量，最后当h减到1时，进行一次插入排序，排序就完成。增量序列一般采用：ht=2t-1,1≤t≤[log2n]，其中n为待排序序列的长度。-Hill sorting algorithm: the basic idea: the whole sequence disorder is separated into a number of small sub-sequences respectively Insertion Sort. Sequence segmentation method: h will be separated by an incremental elements constitute a subset of sequences. In the sort process, the successive decrease of the increment, and finally reduced to one when h when an insertion sort, sort completed. Incremental sequence generally use: ht = 2t-1, 1 ≤ t ≤ [log2n], in which n is the length of sequence to be sorted.
