pdf怎么解除密码？给加密PDF解密的方法情况一：如果知道密码
如果知道PDF文件的密码，操作相对比较简单，这里会使用到PDF编辑工具Foxit PDF。

1.打开安装好的PDF编辑器，点【快速打开】查看我们需要解除密码的PDF文件，然后在弹出的输入框内输入密码；
2.点击【保护】-【删除安全设置】，即可把之前的密码解除。

保存后下次查看就不需要再次输入密码了。

情况二：如果忘记密码
如果忘记了之前设定的密码，那就需要借助PDF365这个在线网站。

1.进入网站，点击导航栏的【所有工具】，在文档处理分类下找到【PDF去密码】功能；
2.在跳转的页面内上传文件后，接着在弹出的输入框内填上通用的默认密码“123”，然后点击【开始去除】，即可将密码解除了。

Word文档的安全问题逐渐进入了人们的视野。

找到一种高效的破解或恢复被加密Word文档的密码的方案具有重要的意义。

密码的暴力破解是最简单也是最常用的破解方法，但是传统的基于CPU的破解方法破解速度慢，大大限制了暴力破解的应用。

文中在分析Word文档加密漏洞的基础上，提出了基于GPU的CUDA并行计算模型，实现了对Word文档加密密码的快速暴力破解，实验证明文中的密码破解方案大大提高了破解速度。
