Description: :ＤＥＳ体制是ＩＳＯ颁布的数据加密标准,通过对ＤＥＳ算法的分析,提出了用Ｃ语言实现数据加密标准ＤＥＳ算法,通过循环或迭代,将简单的基本运算(例如左移、右移、模2加法等)和变换(选择函数、置换函数)构造成数据流的非线性变换(加密变换或解密变换),从而实现对计算机数据进行密码保护。着重介绍了用Ｃ语言实现其加密的主要过程。关键词:数据加密 ＤＥＳ Ｃ语言-: DES system is ISO issued by the Data Encryption Standard, DES algorithm on the analysis of the C language standard DES data encryption algorithm, or through iterative cycle of simple basic operations (such as bits, death, die two Adder, etc.) and transform (choice function, function replacement) structural data streams into the nonlinear transformation (encryption or decryption transform Transform), thereby achieving data on the computer password protection. Highlights of the C language to achieve its key encryption process. Keywords : DES data encryption C language Platform: |

Description: What Does the code DO? Sometimes we may desire to hide our file contents from others.One of the possible way is encrypting these files.Here a simple encryption technique is used(In VB - The same technique can be implemented in "c" also.) Program flow Explained * Open the File to be encrypted for Binary Access Read(Say Source File) * Open a temparory file where encrypted data is stored for Binary Access Write(Say Destination File) * Loop through the Source File Byte by Byte * For each byte read from the file, Complement the data. (Using Not operator (in C we have to use "~" operator) * Write Complemented Data to Destination File * Delete the Source File * Rename Destination file as Source File(Now Encryption is over) -What Does the code DO?

Description: 现在制作外挂的大多都遇上一个问题，就是找不到龙族进程。其实很简单，因为大家使用的都是Findwindows函数，这个函数需要得到窗体的类名才能获得窗体句柄。而现在窗体类名已经被官方加密，等于说Findwindows函数已经彻底被屏蔽了，很多想写龙族外挂的都卡在了这一步上。
其实要破这个限制很容易的，官方现在不再隐藏进程里的dragonraja.bin，所以我们完全可以放弃Findwindows函数转向从进程上下手！
这里公布一段VB原代码，作用是怎样获取指定的进程！-Now most of the production of plug-ins are a problem encountered is that the process can not find nationality. Is actually very simple, because we all are used Findwindows function, this function needs to be a form of class name to get form handle. And now form the class name has been the official encryption, mean that Findwindows function has been completely shielded, many want to write plug-nationality of all cards in this step on. In fact, we would break the limit quite easy now no longer hide the process of the official s dragonraja.bin, so we can give up Findwindows function shifted from the process to gain the upper hand! Published here for some VB source code, is the process of how to obtain the specified! Platform: |
