问题
is there an library or a simple way how to open a password protected ZIP archive in Android? I know there are different types of ZIP encryption. I would like to open the most simple one, create in Unix with the zip -e command. The same file can be opened in Windows (which will ask for password). That should be the standard ZIP 2.0 encryption? How can I open it?
I search for all alternatives but I didn't find any final solution.
回答1:
I found a .jar library that works on Android and can decompress and decrypt ZIP 2.0 files. http://www.lingala.net/zip4j/download.php
It worked for me (encrypted ZIP created in Ubuntu and decrypted in Android).
There might be a way to get it done without any library as described here: Implementation of ZipCrypto / Zip 2.0 encryption in java, but I was not able to get this code to work.

Check out http://code.google.com/p/winzipaes/
And there are several questions here tagged in Java dealing with Zip encryption you might look at.

You can also take a look at this library that can zip and unzip files with password easily:
Unzip:
ZipArchive zipArchive = new ZipArchive();
zipArchive.unzip(targetPath,destinationPath,password);
The documentation of this library is good enough, I just added a few examples from there. It's totally free and wrote specially for android.
