知道密码后，删除PDF密码保护 [英] Removing PDF password protection, knowing the password

问题描述

我有一堆pdf文件，我想从中删除密码.请注意，我知道密码，因此不需要强行使用.我正在Mac电脑上工作，因此我想开发一个应用来删除这些密码.

I have a bunch of pdf's I want to remove passwords from. Note that I know the password, so no need for brute forcing. I am working on a mac, so I would like to make an app to remove those passwords.

我看过诸如Wondershare的pdf密码删除器之类的应用程序，所以我知道这是可能的.

I have seen apps like wondershare's pdf password remover, so I know it is possible.

在obj-c环境中是否有解决方案/库可以从PDF的密码中删除密码?

Is there a solution/library in the obj-c environment to remove passwords from PDF's?
