Next
Kill sPath & "\" & sFile & ".tmp"
If iCRC = nCRC Then
MsgBox "密码为:" & sWord
Exit Sub
End If

(4)单击“运行”按钮运行代码,程序将开始破解密码。
三、忘记密码时的应急方案
如果您忘记了Word文档的密码,也可以尝试以下应急方案:
1. 利用备份文件
如果您做了此文件的备份,可以尝试打开备份文件。如果没有备份文件,请接着往下看。
2. 利用XML编辑器
将Word文档的后缀名改为“.zip”,用压缩软件解压缩后进入“word”目录,找到名为“settings.xml”的文件,使用文本编辑器打开并搜索“<w:documentProtection”等关键字,将“w:enforcement”属性的值改为“0”,保存后重新压缩文件并将后缀名改回原来的格式。重新打开该Word文档,密码保护已经被去除。
3. 利用第三方软件解密
您可以使用第三方软件,如Advanced Office Password Recovery或Office Password Recovery来解密Word文档,以便您可以打开和编辑该文档。这些工具很强大,可以破解大多数保护措施,但也需要付费。
总结
破解Word文档密码需要使用专业的工具和技巧,但是我们仅在自己拥有的文档上进行密码破解。对于他人拥有的文档,我们不应进行非法破解行为。
