DES(Data Encrypton Standard) 算法的实现网上已经有很多，本人在此讲述的是在DES算法加密过程中如何查看16迭代过程中生成的Ki,Li,Ri,Fi,Si等，这样可以当做一个DES加密对照器，这样可以方便的发现你在加密过程中出现的错误! -DES (Data Encrypton Standard) algorithm has been achieved online many, I would like to speak on is the DES encryption algorithm to see how the process 16 iterative process of generating Ki, Li, Ri, Fi, Si, etc., can serve as a control device DES encryption, this can easily find you in the process of encryption the mistakes!

组播密钥的批次更新算法，基于LKH的单次密钥更新方案和Batch Rekeying方案的原理、结构和密钥更新过程等。并着重对 Batch Rekeying 方案的性能与单次密钥更新方案作了简单的比较。 通过比较和分析得到结论:定时更新的Batch Rekeying 方案在更新开销上比单次更新更有优势 -Multicast key batch update algorithm, Based on the LKH single Rekeying program and the program Batch Rekeying principle, Rekeying structure and processes. And Batch Rekeying focused on the performance of the program with a single Rekeying program with a simple comparison. By comparing and analyzing conclusions : regularly updated Batch Rekeying program in the updated overhead than a single update more advantages

这个小软件通过在可执行文件(.exe)的尾部添加一个新节(Section)，并且修改PE的入口地址，使可执行文件在运行时，跳出一个输入密码的对话框，从而实现了简单的加密。-small software in executable files (. Exe) to the tail adding a new section (Section), and amend the PE import addresses, so that the executable file is run, jump out of a password dialog box, thus achieving a simple encryption.

此代码提供关键时间表中的数据加密标准 (DES)，这是生成子密钥的算法的实现的。 • 输入： （长度 （64 位） 的任何字符串。 • 输出： 16 子键产生的 DES （每个 48 位长度）。 如何使用它： 1.>> K = DES_KeyScheduling %会创建一个类 "DES_KeyScheduling" 的对象。 2.>> K.KEY_STRING = "密码" %设置的加密密钥值。 3.>> K.printPC2() %打印输出的置换选择 2 （PC-2） （也称为 x 16 48 及其子键） 无压痕。用来调用函数 1 "K.printPC2(1)" 要输出带缩进值。
