rsa加密攻击源程序 C语言 This tool is supposed to help crackers who are cracking targets protected by RSA and who aren't attackable by the classic method of factoring i.e who'se modulus is > 400 bits. .How to use *********** It's very easy to use it once you know the when the attacks apply.So here are the explanations: 1.Common Modulus Attack: not really an attack but more of a tool, its purpose is to find the factors of the modulus given the public AND secret key, i.e E and D So entering N,D,E you find P,Q so that N = P * Q. I included it in this 'toolkitt' as i got asked many times by other crackers if you can find the factors of N given D and E is possible. The answer is yes. The algo which i used can be found here: http://math.usask.ca/~wurtz/crypt/attacks_rsa/node1.html 2. Weger Attack: this attack applies when the factors of N are close one another i.e the diference |P - Q| is small in comparison to P and Q. So if let's say P and Q have the same bitsize s than for the RSA key to be susceptible to this attack then |P-Q| bitsize must be smaller then (s/2) E.g. P bitsize=256 bits Q bitsize=256 bits |P-Q| bitsize is 100bits then they key generated with this primes is attackble. When testing a RSA key for this attack if you don't get any result after at most 5mins then the attack don't work. BTW: you can try this attack on Amenesia Basis#1 Crackme that presents an RSA key with exactly this weakness. 3. Wiener Attack: this attack applies when the private key is D < (1/3)*N^(1/4) and if P < Q < 2P (which is true most of the times.). So if you have an s bit modulus and if the bitsize of the private key is < (s/4) bits than you can succesfully recover. The attack can be improved, but i'm lazy so i only did the easier version :). 4. Low Exponent Attack: If E=3 and the message is short enough and not padded then there's a possibility that M^E < N so the modular reductions don't take place so computing M having the ciphertext is just a matter of computing the E'th root from the cipher text. As input you must provide N and the ciphertext BTW: you can try this attack on Amenesia Basis#2 Crackme that presents an RSA key with exactly this weakness. .Bugs ****** Send them to [email protected] or correct them yourself, i gave you the source right? :) .Future plans ************* - add threads for Weger attack - add Cycling attack - i need to find more info about how to efficiently implemented (i know it's not an efficient attack from the start but people asked for it) - add ? (here you put what you think is missing) .History ********* - v.0.1f - added the low public exponent 'attack' :) - added automatic base convertion, so it's easier to work with - added automatic md5 hasher (a request) - added Encrypt/Decrypt functions to play with the RSA keys - v.0.1b - first version released .Greets ******* RET, TKM!, KANAL23, LZ0 Members as they all put up with my stupid questions :P

一个供高级用户使用的强大的文件和夹重命名工具。它提供了多种重命名选项，包括删除数字或字符串，替换字符串，插入数字，转换字符，组织数值等等。支持正则表达式，并支持给音频、图像及其他文档更改扩展名。 它还能从包含的信息Tags中 (ID3, EXIF, IPTC, DOC, HTML)智能重命名文件，能创建一个看其名就知其义的文件名。 其他的功能包括文件名预览，创建空文件和文件夹，以及资源管理器右键扩展等。

【软件介绍】 小巧好用的鼠标点击器。可以定义次数，可以一直点击。 记得汉化者在玩某款游戏中不停的点击鼠标，然后找到了本软件。 其录制功能十分强大，可以录制点击的先后顺序，然后不停的执行。 【文件结构】 -- |- AutoClick_CHS.exe 主程序 |- 汉化说明.txt 【其他说明】 软件运行后会生成配置文件，不会写注册表。 如果想要不生成配置文件的版本，请单独密我。 软件在录制点击的时候的动态光标在汉化过程中丢失，故替换为其他光标。 另外感谢听雨醉帮忙校正了某些单词。谢谢！

假如你想一下子创建100个或者更多个文件夹,你会怎么办？一个个复制显然是不行的，那么下面的批处理语句可以帮助你轻松搞定： ::------------------------------------------------------------------------------------------ @echo off for /L %%x in (1,1,10) do md 文件夹%%x for /L %%x in (1,1,10) do @echo %%x>文件夹%%x\%%x.doc ::------------------------------------------------------------------------------------------ 将上面紫色文字复制进记事本另存为:批量.bat 双击运行可在当前文件夹创建10个文件夹，名字分别为：文件夹1、文件夹2、......文件夹10,并且每个文件夹中包含一个word文档. 解释： 1、@echo off 这句非必须，表示不显示运行过程 2、FOR /L %变量 IN (开始,步长,结尾) DO 命令 [命令参数] 该集表示以增量形式从开始到结束的一个数字序列。 因此，(1,1,5) 将产生序列 1 2 3 4 5， (1,2,9) 将产生序列 1 3 5 7 9，(5,-1,1) 将产生序列 (5 4 3 2 1)。 很是实用，特来分享！
