A-PDF 密码安全是一个桌面实用程序，允许您更改现有 Acrobat PDF 文件的密码安全性。这意味着您可以使用 128 位加密保护 PDF 文件或删除密码保护。它可以处理单个或批处理文档。另一个方便的功能包括密码池和热目录。 使用 A-PDF 密码安全设置，如果需要密码才能打开和/或有访问限制，您可以设置 PDF 文件。例如，允许或不允许打印、复制内容或更改文件等。您可以同时修改元数据，包括作者、标题、主题和关键字。A-PDF 密码安全甚至支持禁用/启用过期功能。 A-PDF 密码安全适用于未加密或加密的 PDF 文件，不需要 Adobe Acrobat。 密码池：如果您需要用一个密码对一批 PDF 文件进行不安全，可以特别使用密码池。A-PDF 密码安全部门将一个尝试密码，而不是手动输入密码。 热目录：您可以设置一个受监视的目录，其中写入该目录的所有文件将在保存时进行加密。原始文件也可以移动到备份目录。所有操作都将记录在日志文件中。
