apache-flex - Adobe AIR (Flex) 中的文件保护

Question

是否可以在 AIR 应用程序中下载文件，将其存储在用户系统中，并禁止与下载该文件的应用程序不同的应用程序访问这些文件？

Answer 1

在 Windows 上肯定不容易做到。加密它的内容可能会更好。

编辑：创建其他程序无法访问的文件是非常类似病毒的行为。

Answer 2

加密确实可能是要走的路。AIR 确实有一个方便的加密本地存储，它应该为您简化这种方法：

Answer 3

Your best bet is to store the contents of the file in the EncryptedLocalStore or a local shard object. While you can store the downloaded file in a directory on the user's file system, you aren't going to be able to prevent it from being accessed by other applications (or the user) on the system. That's a security issue because that's how a lot of viruses work.
