如何创建普通的受密码保护的ZIP存档? [英] How to create a normal password-protected ZIP archive?

问题描述

我的应用压缩了几个文件，将压缩文件保存到SD卡，然后通过电子邮件将压缩文件发送到一个地址.

My app zips several files, saves the zip file to the SD card, and it emails the zip file to an address.

使用以下代码进行压缩:使用Android(以编程方式)压缩文件.

The zipping is done with this code: Zipping Files with Android (Programmatically).

现在的问题是，我如何在zip文件中输入密码，以便在计算机(Windows，Mac或Ubuntu)上打开该文件的授权人员能够使用提供的密码提取文件?

Now the question is, how do I put a password on the zip file so that authorized individuals who opens it on a computer (Windows, Mac, or Ubuntu) would be able to extract the files with a supplied password?

我阅读了这篇文章: Android zip文件身份验证，但对我来说听起来像是的拉链是用另一部手机完成的...还是我错了? 如果有人知道，请告诉我！谢谢！

I read this post: Android zip file authentication, but it sounds to me that reading of the zip is done with another phone... or am I wrong? If anybody knows please let me know! Thanks!

推荐答案

由于Android具有JVM，因此您可以尝试使用对Java看到的所有lib(有些可以运行，有些不能运行，而某些库的更改会也可以).

since Android has a JVM , you can try to use all lib that you see for java (some will run , some not , and some changes of some library will be ok too) .

这样，我将复制过去此回答问题(用Java编写受密码保护的Zip文件):

This way i'll copy past this answer fo the question (Write a password protected Zip file in Java):

经过大量搜索，我发现了三种方法:

After much searching, I've found three approaches:

可免费获得的一组源代码，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，并在以下位置发布 http://code.google.com/p/winzipaes/.它对我有用(一个文件在 zip)，并很好地填补了Java开放源代码库中的一个空白.

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.

一种商业产品(在撰写本文时为500美元).我无法验证 这是可行的，因为他们的试用许可证方法很复杂.它也是 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

一种商业产品(在撰写本文时为290美元).仅适用于 Wnidows使用dll: http://www.example-code.com/java/zip.asp

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

您还必须知道，将它们适应Android可能并不容易，但是也许您很幸运，其中一些将立即为您运行.

祝你好运！
