我忘记了打开 Word 文档的密码。我怎样才能找回密码？

Question

我有一个word文档，提示用户输入密码打开它，对话框如下。

"Enter Password to open file"

我在下面找到了一些使用暴力破解密码的代码（用 Excel 编写）。唯一的问题是当我使用 Documents.Open 如果密码错误的话会显示对话框 - 无论如何都可以绕过这个吗？

Answer 1

在尝试打开文件之前立即使用 SendKeys "{ESC}"。

Answer 2

文件需要是.docx格式，如果是.doc转换成.docx:

创建文件的备份副本。
将扩展名从 .docx 更改为 .zip。
打开新的 .zip 文件并提取所有文件。
在提取的文件夹中转到 word\settings.xml。
打开 settings.xml 并删除从 <w:documentProtection 到 /> 的代码并保存文件。
将新的 settings.xml 复制到原始 .zip 文件并覆盖旧文件。
将 .zip 重命名为 .docx 并打开现在不受保护的文件！

Answer 3

如"Matt"所述，只需将文件扩展名转换为 .zip，然后使用记事本或记事本++编辑 .xml 文件，删除 w:documentprotection 之后的整行/> 然后重新保存 .zip 文件夹中的新 .xml 文件将删除密码保护。在 Word 2016 中尝试和测试。只是不要忘记将现在编辑的 zip 文件夹重命名回 .docx，以便它在 Word 中可读。全部归功于马特。

Answer 4

我调整了你的原始代码，所以它不依赖于一定长度的密码。此外，它现在将从左向右移动，每次通过都会添加一个新字符，并防止在尝试打开文档时出现弹出窗口。这也可以用于工作簿。

警告** 蛮力法真的不值得。运行需要很长时间。如果是加密密码，那么这可能是不下载第三方密码破解器的最佳选择。
