《pdfpasswordrecovery使用指南》

pdfpasswordrecovery是一款用于恢复pdf文件密码的工具。

使用时，首先打开pdfpasswordrecovery软件。如果是要恢复打开密码，将加密的pdf文件导入到软件界面。软件会根据设定的密码恢复类型（如暴力破解、字典破解等）开始尝试破解密码。暴力破解会尝试所有可能的字符组合，但可能耗时较长；字典破解则是依据内置或自定义的字典文件中的词汇来寻找密码。

若是要去除权限密码（如禁止打印、编辑等权限密码），同样导入文件后，软件会快速解析并去除这些限制，使pdf文件能够自由地进行打印、编辑等操作。在使用过程中，需确保使用的合法性，仅用于合法获取自己有权限访问的pdf文件密码。
