文件加密与内容加密是否不同 [英] Is file encryption different from content encryption

问题描述

加密文件和加密文件内容之间是否有任何区别。如果是这样，怎么做都可以。

Is there any difference between encrypting a file and encrypting the content of the file. If so, how to do the both.

推荐答案

文件加密是从外部对整个文件进行加密（例如，通过右键-在Windows XP资源管理器中单击）。内容加密通常用作文件加密的同义词，但是两者有所不同。内容加密是指对文件的内容或文件的部分内容进行加密。

File encryption is encrypting a whole file, from the outside (e.g. by right-clicking in Windows XP Explorer). Content encryption is generally used as a synonym for file encryption, but the two things are different. Content encryption means encrypting the contents of a file, or part of the contents of a file.

考虑视频流。例如，我们可能想对高清视频进行加密，以便任何人都可以看到低分辨率版本，但只有付费订户才能获得高质量的视频流。我们无法通过加密整个视频文件来做到这一点。

Consider video streaming. For instance, we might want to encrypt an HD video so that anybody can see the low-res version but only paying subscribers get the top quality stream. We cannot do that by encrypting the whole video file.
