我被要求更新一些Excel 2003宏,但是VBA项目有密码保护,而且似乎缺乏文档…没人知道密码。
是否有一种方法可以删除或破解VBA项目的密码?

接受的答案在Windows 10上的Excel 2019中无法正常工作。找到了查看锁定宏所需的额外步骤。我正在总结步骤。
Add a .zip to the end of the excel filename and hit enter Once the file has been changed to a ZIP file, open it by double clicking on it Inside you would see a folder called xl like below Inside xl, you'll find a file called vbaProject.bin, copy/paste it on the desktop Go to the online Hexadecimal Editor HexEd.it Search for the following texts DPB=... and change them to DPx=... Save the file and close HexEd.it Copy/Paste the updated file from your desktop inside the ZIP file (you would need to overwrite it) Remove the .zip extension from the end of the filename and add the excel extention again. Open the file in excel - you may receive a couple of error notifications, just click through them.
====在接受的答案=====之外的额外步骤
Open the Visual Basic window (usually ALT+F11 if I remember correctly) and open the VBAProject properties (Tools menu). Click on the Protection tab and change (do not remove at this stage) the password to something short and easy to remember (we'll be removing in next step). Save the workbook and then close and reopen. Open again the Visual Basic window and enter the password you just put in. Redo the previous step but this time you can remove (delete) the password. Save the workbook and you have now removed the password.

Colin Pickard is mostly correct, but don't confuse the "password to open" protection for the entire file with the VBA password protection, which is completely different from the former and is the same for Office 2003 and 2007 (for Office 2007, rename the file to .zip and look for the vbaProject.bin inside the zip). And that technically the correct way to edit the file is to use a OLE compound document viewer like CFX to open up the correct stream. Of course, if you are just replacing bytes, the plain old binary editor may work.
顺便说一句,如果你想知道这些字段的确切格式,他们现在有文档:

ElcomSoft提供高级办公密码破断器和高级办公密码恢复产品,只要文档是在Office 2007或更早版本中创建的,就可以适用于这种情况。
对于.xlsm或.dotm文件类型,您需要以稍微不同的方式进行操作。
Change the extension of the .xlsm file to .zip. Open the .zip file (with WinZip or WinRar etc) and go to the xl folder. Extract the vbaProject.bin file and open it in a Hex Editor (I use HxD, its completely free and lightweight.) Search for DPB and replace with DPx and save the file. Replace the old vbaProject.bin file with this new on in the zipped file. Change the file extension back to .xlsm. Open workbook skip through the warning messages. Open up Visual Basic inside Excel. Go to Tools > VBAProject Properties > Protection Tab. Put in a new password and save the .xlsm file. Close and re open and your new password will work.
Tom -我最初犯了一个学生错误,因为我没有注意字节大小,而是从“CMG”设置复制粘贴到后续条目。这两个文件之间有两种不同的文本大小,但是,正如Stewbob警告的那样,我丢失了VBA项目。
使用HxD,有一个计数器跟踪您选择了多少文件。从CMG开始复制,直到计数器读取8F(十六进制为143),同样地,当粘贴到锁定文件时-我最终在粘贴的末尾使用了两倍的“…”,这看起来有点奇怪,感觉几乎不自然,但它起作用了。
我不知道这是否重要,但在excel中重新打开文件之前,我确保关闭了十六进制编辑器和excel。然后我必须通过菜单打开VB编辑器,进入VBProject属性,并输入'new'密码来解锁代码。
我希望这能有所帮助。
如果你使用Java,你可以尝试VBAMacroExtractor。在从.xlsm中提取VBA脚本后,我发现了明文密码。
