关于用于压缩文件的免费库的建议 [英] Recommendations on a free library to be used for zipping files

问题描述

我需要对文件进行压缩和密码保护.有没有好的(免费)图书馆?

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

这需要第三方打开，所以密码保护需要使用标准工具.

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

推荐答案

UPDATE 2020:现在还有其他选择，特别是 Zip4J.

UPDATE 2020: There are other choices now, notably Zip4J.

经过大量搜索，我找到了三种方法:

After much searching, I've found three approaches:

一组免费提供的源代码，适用于单个文件 zip.但是，没有许可证.用法是 AesZipOutputStream.zipAndEcrypt(...).http://merkert.de/de/info/zipaes/src.zip(https://forums.oracle.com/forums/thread.jspa?threadID=1526137)

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)

更新:此代码现已获得 Apache 许可并在 https://github.com/mobsandgeeks/winzipaes(从 Google 代码 的原始主页导出).它对我有用(zip 中有一个文件)，并且很好地填补了 Java 开源库中的一个漏洞.

UPDATE: This code is now Apache licensed and released at https://github.com/mobsandgeeks/winzipaes (exported from original home at Google code) . It worked for me (one file in the zip), and fills a hole in Java's opens source libraries nicely.

商业产品(撰写本文时为 500 美元).我无法验证这是否有效，因为他们的试用许可方法很复杂.它也是一个移植的 .NET 应用程序:http://www.nsoftware.com/ipworks/zip/default.aspx

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

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