在Java中编写受密码保护的Zip文件 [英] Write a password protected Zip file in Java

问题描述

我需要压缩和密码保护文件。有没有一个很好的（免费）的图书馆？

这需要由第三方打开，所以密码保护需要使用标准工具。 >

解决方案

经过多次搜索，我发现了三种方法：

可用的一套源代码，适合单个文件zip。但是，没有许可证。用法是AesZipOutputStream.zipAndEcrypt（...）。

（ https://forums.oracle.com/论坛/ thread.jspa？threadID = 1526137 ）

更新：此代码现在是Apache授权并在 http://code.google.com/p/winzipaes/ 。它为我工作（在zip中有一个文件），并且很好地填充了Java的开源库中的一个洞。

商业产品（写作时为500美元）。我无法验证是否有效，因为他们的试用许可证方法很复杂。它也是一个移植的.NET应用程序：

商业产品（写作时为290美元）。仅适用于Wnidows，因为它使用dll：
http：//www.example -code.com/java/zip.asp

I need to zip and password-protect a file. Is there a good (free) library for this?

This needs to be opened by a third party, so the password protection needs to work with standard tools.

解决方案

After much searching, I've found three approaches:

A freely available set of source code, suitable for a single file zip. However, there is no license. Usage is AesZipOutputStream.zipAndEcrypt(...). http://merkert.de/de/info/zipaes/src.zip (https://forums.oracle.com/forums/thread.jspa?threadID=1526137)

UPDATE: This code is now Apache licensed and released at http://code.google.com/p/winzipaes/ . It worked for me (one file in the zip), and fills a hole in Java's opens source libraries nicely.

A commercial product ($500 at the time of writing). I can't verify if this works, as their trial license approach is complex. Its also a ported .NET app: http://www.nsoftware.com/ipworks/zip/default.aspx

A commercial product ($290 at the time of writing). Suitable only for Wnidows as it uses a dll: http://www.example-code.com/java/zip.asp
