航海英语听力与会话加密光盘破解方法

加密光盘破解不完全功略第一部分，图片音乐光盘的破解一般加密光盘最常用的加密方法就是加密目录让你在windows 自带的资源管理器中无法看到这个隐藏的目录(当然不会只是加个隐藏属性那么简单了)。

然而dos(windows中自带的dos即可)往往可以看到和进入这些本来被隐藏的文件夹。

我们以我的卡通音乐mp3的cd为例子，正常情况下我们看到的文件和目录的情况是这样的:h:\\>dir驱动器h 中的卷是2000_64卷的序列号是d285-3a07h:\\ 的目录04/09/1997 22:26 27 autorun.inf07/29/2000 21:27 <dir> browse07/29/2000 19:44 <dir> image04/23/1997 11:45 450，048 setup.exe07/30/2000 19:38 214 说明.txt3 个文件450，289 字节2 个目录0 可用字节(其中h:\\盘就是我的光驱)，那么会不会是h盘的目录隐藏了呢？那么:h:\\>dir /a驱动器h 中的卷是2000_64卷的序列号是d285-3a07h:\\ 的目录04/09/1997 22:26 27 autorun.inf07/29/2000 21:27 <dir> browse07/29/2000 19:44 <dir> image04/23/1997 11:45 450，048 setup.exe07/30/2000 19:38 214 说明.txt3 个文件450，289 字节2 个目录0 可用字节看来除了browse和image并没有其他目录了，可是我的mp3文件存放在哪里了呢？让我找找看吧:h:\\>dir *.mp3 /a/s/p驱动器h 中的卷是2000_64卷的序列号是d285-3a07找不到文件没有？这说明什么----这是一个非一般隐藏属性的隐藏目录(如果假设这些mp3在一个目录中的话)，于是我通过autorun进入文件的目录中，随便打开一个mp3文件，查看它的属性(我用的是win自带的mediaplayer，方法是file(文件)-properties(属性)中的location(位置)为”h:\\d r2\\头文字d歌唱集\\track 02.mp3”，嗯？这是什么？--“h:\\d r2\\”看到了吗，这里有一个隐藏的目录，这就是我们要找的目录!好，现在我们试着进入它:(注意这里的步骤!)首先:h:\\>cd d r2h:\\d r2>dir驱动器h 中的卷是2000_64卷的序列号是d285-3a07h:\\d r2 的目录07/29/2000 19:43 <dir> .01/01/1601 01:00 <dir> ..02/23/1997 10:46 51 _system1.dat05/03/1997 00:04 461，312 filelist.exe07/30/2000 18:58 <dir> gs美神歌集07/30/2000 19:01 <dir> gto07/30/2000 19:01 <dir> winamp04/06/1997 03:03 0 ~_9a90bc.tmp07/30/2000 19:01 <dir> 不思议游戏歌集07/30/2000 19:01 <dir> 纲铁神兵主题歌集07/30/2000 19:01 <dir> 梦幻模擬战v歌集07/30/2000 19:01 <dir> 青之六号07/30/2000 19:01 <dir> 他和她的故事i07/30/2000 19:01 <dir> 他和她的故事ii07/30/2000 19:01 <dir> 他和她的故事iii07/30/2000 19:01 <dir> 头文字d歌唱集07/30/2000 19:01 <dir> 下级生07/30/2000 19:01 <dir> 校园放送部3 个文件461，363 字节15 个目录0 可用字节好，dos里没有问题，我们试试在资源管理器中打开:开始---运行---键入“h:\\d r2”系统会出现如下提示:该文件没有程序与之关联来执行该操作。

如何破解光盘的加密5招加密光盘是以特殊形式刻录的。

放入光驱后，会出现一个软件的安装画面要你输入序列号，如果序列号正确就会出现一个文件浏览窗口，错误则跳回桌面。

如果你是从资源浏览器中观看光盘文件就是一些图片之类的文件，你想找的文件却怎么也看不到。

如果你的光盘序列号丢了或者光盘上的序列号根本不对，那怎么办？第一式：用UltraEdit等16进制编辑器直接找到序列号运行UltraEdit，用它打开光盘根目录下的SETUP.EXE，然后点击菜单上的“搜索”＝》“查找”，在弹出的对话框“查找什么”栏中填入“请输入序列号”，注意要将多选框“查找ASCII字符”勾选上，回车，在找到的“请输入序列号”后面，接下去的数字就是序列号了。

第二式：用IsoBuster等光盘刻录软件直接去浏览光盘上的隐藏文件运行IsoBuster，选择加密盘所在的光驱，点击选择栏旁边的刷新按钮，此时它就会读取光驱中的文件，这时你就会发现在左边的文件浏览框中多出一个文件夹，那里面就是你真正想要的文件。

这时你就可以运行或复制这些文件了。

第三式：要用到虚拟光驱软件（如Vcdrom，虚拟光驱2000）和16进制编辑器（如UltraEdit，WinHex）1用虚拟光驱软件把加密光盘做成虚拟光碟文件，进度到1%的时候就可以按Ctrl+Alt+Del组合键强行终止虚拟光驱程序的运行2用16进制编辑器打开只做了1%的光碟文件（后缀名为vcd或fcd的文件），在编辑窗口中上下查找任意看得见的目录名或文件名（由于文件不大很容易找到的），在该位置的上下就可以看见隐含的目录名或文件名了（一般是目录名）3在MS-DOS窗口下用CD命令进入看到的那个目录，再dir一下就可以看到你想要的了第四式：在光驱所在盘符下执行：dir2filelist.exe即可运行浏览程序（filelist.exe为隐藏的浏览光盘的程序）第五式：利用File Monitor对付隐藏目录的加密光盘File Monitor这个软件是绿色软件，可监视系统中指定文件运行状况，如指定文件打开了哪个文件，关闭了哪个文件，对哪个文件进行了数据读取等。

新方法破解和复制加密光盘
光盘加密WINISO等都无法把光盘的内容复制或拷贝出来。

经过反复查证和实验终于找到了简单快捷的方法：
一般光盘加密的原理就是：在碟片的内圈上添加了一个加密圈，其实是人为的制造了一圈坏道，这样你会发现光盘可以显示容量，可以播放但打开目录。

却没有任何文件或极少无用的文件，这道坏圈使光驱从物理上不能正常的读取文件，这个用NERO的复制CD也是不行的，因为NERO也不能读过坏道。

破解它需要用UltraISO即可，可上网下载。

1、放入要复制的光盘，运行UltraISO——点击“工具→制作光盘映像文件”，选择保存的路径。

2、保存的ISO文件，用WinRAR查看你会发现几百兆的文件里面只有几十兆的文件，并且与原光盘的内容完全不同，但用UltraISO打开则看到与原光盘的内容完全同，不用急按下面操作即可破解。

3、用UltraISO打开刚才的ISO文件，选文件——保存，即可破解。

这时同一目录下会多个备份文件，删除即可，新的ISO文件会比原文件少几十兆，其实就是在碟片的内圈上添加了的加密圈的容量。

4、新保存的ISO文件，用WinRAR查看你会发现里面的文件与原光
盘的内容完全同，ISO文件用虚拟光驱加载即可。

人机对话口语考试系统软件加密技术破解研究深圳市高级中学丁辉人机对话口语考试系统，是英语听说考试与练习一大创新，对提高学生英语听说，有很大的帮助。

人机对话口语考试系统分为三大部分：服务端、制卷系统、评卷系统，这三个程序都是用SafeNet China 公司soft-dog 加密狗，没有狗，就不能运行，若狗出现问题，那这三个程序就没有过办法运行，为了便于备份，于是就研究它的程序用加密狗保护，效果怎样，看能不能把狗打死了。

所用到检测软件有：1、检测软件PEiD v0.94，看软件用什么程序加密及什么语言编写；2、反编译软件C32Asm-v0.4.12，对程序进行反编译，通过汇编语言，来研究程序如何跳过程序保护；3、注册机编写器keymake2.0 修改版，是一个很方便编写内存注册机、文件补丁及内存补丁程序。

我们以评卷系统为例来说明加密技术解密,都是在没有狗的条件测试：1、首先运行评卷系统ProCA,出现提示信息图1 如下：加密狗检测失败，我们就从这个信息入手。

图1 图22、检测软件PEiD v0.94，检测评卷系统ProCA，加密了没有用什么语言编写。

出现是没有加密用的是Delphi 6.0-7.0 语言编写,图2。

那说好办多了。

3、我们就用反编译软件C32Asm-v0.4.12，来打开评卷系统proca.exe，并在字条串调用下面输入"加密狗检测失败"，打回车，并把MOUSE 移动这里如图3 所示图 3就是这段代码::00905748:: 64:8920 MOV DWORD PTR FS:[EAX], ESP::0090574B:: A1 882F9100 ::00905750:: 8B10::00905755:: 84C0::00905757:: 75 43::00905759:: E8 0224B9FF ::0090575E:: 84C0::00905760:: 75 1BJNZ ::00905762:: A1 90029100 ::00905767:: 8B00 MOV ::00905769:: BA 84589000 ::0090576E:: E8 394ABDFF ::00905773:: E8 74F5AFFF ::00905778:: E9 F7000000 ::0090577D:: A1 882F9100 ::00905782:: E8 61EFFFFF ::00905787:: 84C0::00905789:: 75 11::0090578B:: A1 90029100 ::00905790:: 8B00 MOV ::00905792:: BA 9C589000 ::00905797:: E8 104ABDFF ::0090579C:: 33C0 XOR::0090579E:: 5A ::0090579F:: 59 ::009057A0:: 59 POPMOVMOVTESTJNZCALLTESTEAX, DWORD PTR [912F88]EDX, DWORD PTR [EAX]AL, ALSHORT 0090579C00497B60AL, AL\:JMPDOWNSHORT 0090577DMOV\:JMPUP\:JMPDOWNEAX, DWORD PTR [910290]EAX, DWORD PTR [EAX]MOVCALLCALLJMPEDX, 905884004DA1AC00404CEC00905874\->: 加密狗检测失败\:JMPUP\:JMPUP\:JMPDOWNMOV EAX, DWORD PTR [912F88] \:BYJMP JmpBy:00905760,CALLTESTJNZMOV009046E8AL, AL\:JMPUPSHORT 0090579CEAX, DWORD PTR [910290]\:JMPDOWNEAX, DWORD PTR [EAX]MOVCALLEDX, 90589C004DA1AC\->: 建立授权文件出错\:JMPUPEAX, EAXEDXPOPPOPMOVPUSH\:BYJMP JmpBy:00905757,00905789,ECXECX::009057A1:: 64:8910::009057A4:: 68 BB579000 DWORD PTR FS:[EAX], EDX 9057BB\->: h 癤?通过分析这段代码，发现，有两处JNZ SHORT 0090579C \:JMPDOWN，第二处肯定不是要找的地方，因为它在MOV EDX, 905884 \->: 加密狗检测失败的下面，那第一处就是要找的地方，JNZ(机器码是75) 当测试条件为Z=0，如不为零/不等于则转移。

破解专业四级听力的关键技巧专业四级听力考试是大多数专业类学生面临的一项重要考试。

在这个听力考试中，考生需要听懂并把握听力材料提供的关键信息，以便回答相关的问题。

然而，由于听力材料的长短和难度，许多考生感到困惑和挫败。

在本文中，将介绍一些破解专业四级听力的关键技巧，帮助考生在考试中取得更好的成绩。

首先，重视平时的听力训练是破解专业四级听力难题的关键之一。

学生可以利用大学期间的课余时间，多听一些与专业相关的英语资料，包括英语新闻、专业讲座和学术演讲等。

这种长期的积累可以提高学生对专业英语的理解能力，并提高他们对不同语言风格和语境的适应能力。

其次，刻意训练听力技巧也是成功破解专业四级听力的重点。

学生可以尝试使用一些听力技巧，如预测、识别关键词和上下文理解等。

预测是指在听力材料开始之前，根据题目的关键词设想可能会出现的答案。

识别关键词是指在听力中特别关注关键词，因为它们通常会直接指向正确的答案。

上下文理解是指综合整个对话或讲座的语境来推测正确的答案。

这些技巧需要在平时训练中不断提高，才能在考试中得心应手。

此外，良好的听力习惯对于破解专业四级听力同样至关重要。

学生需要学会细心聆听，集中注意力，避免分心以及忽略听力材料中的信息。

为了培养良好的听力习惯，考生可以尝试进行一些听力练习，如听写和听后复述等。

这些练习不仅可以提高对听力材料的理解和记忆力，还可以帮助培养耐心和集中注意力的能力。

另外，积极参与互动也是破解专业四级听力的关键技巧之一。

在听力考试中，考生有时需要根据听到的信息回答问题或进行相关的讨论。

在平时的学习生活中，学生可以尝试与同学进行合作讨论、参加小组活动以及积极参与听力实践，以提高自己在听力交流方面的技巧和信心。

最后，保持积极的心态也是破解专业四级听力难题的重要因素。

听力考试可能会遇到一些难以理解的词汇和句子结构，但要相信自己的能力，努力理解并寻找答案。

保持积极的心态有助于缓解紧张情绪，并提高在考试过程中的表现。

破解加密光盘的几种方法破解加密光盘的几种方法方法一隐藏目录最简单的加密方法，把视频DAT文件的属性设置为“隐藏”，VCD 一放入光驱，大部分播放软件即开始搜索此类文件，经过加密后播放软件就无法播放了，而且进入光盘目录也不会显示这些文件，所以从光驱直接把DAT文件复制到硬盘上也是不可行的!破解方法：进入光盘目录，点击上面菜单栏的“工具→文件夹选项→查看”，在“高级设置”里选择显示所有文件和文件夹，这样光盘目录下的DAT 文件就无处遁形了。

方法二自运行程序隐藏光盘这种新型的VCD为了在一定程度上防止盗版，特别制作了一个程序，若把这个VCD放入电脑光驱，此程序会自动运行对光碟进行屏蔽，不能被所有的主流播放器认识，故不能播放。

破解方法：可是这程序的作者毕竟还是犯了一个极大的错误，使这种加密方法一触即破。

就是在第一次放入此类光盘时，必须先按键盘上的Shift 键，禁止光盘自动运行，这个屏蔽程序就不能安装，就此废了这个功能。

记住，只有一次机会，若是第一次放入此类光盘时，让屏蔽程序无声息地安装了，就无法破解了，此程序在添加删除程序中是看不见的。

笔者建议可以关闭光驱属性中的自动插入通告，这样就不必每次按Shift手动操作了。

方法三人工光盘坏道目前最新的加密方法，原理是该VCD带防盗圈，这个圈的作用是在光头读盘到防盗圈处时是个坏道，从物理上让光驱读不过去，你会发现光盘可以显示容量，但打开目录却没有任何文件，市面上的无间道2、天地英雄、大块头有大智慧等最新VCD都是采用这种加密方法。

破解方法：步骤1：首先我们需要CloneCD这个软件，下载地址：天极网下载频道。

注意不能使用NERO等其他光驱软件，因为NERO读不过坏道，可能造成死机的情况。

首次运行在Language语言栏内选择SIMP.Chinese，界面显示为中文。

点击“文件→读成映像文件”，在弹出的对话框中选择物理光驱的盘符，注意不能选择虚拟盘符。

选择后CloneCD会对整个VCD 进行扫描，由于制作的是视频镜像，所以选择multimedia audio cd，然后选择镜像文件保存目录，右面已经显示出扫描后光盘的容量、片断、轨道数等一些信息。
