Open password protected ZIP in Android?

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.

Solution

  • 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.
