How to unzip a password-protected archive created by Linux, using Java

Question

I am working on an Android project recently and met an issue. I send a request to webservice and got a zip file with password protection. The zip file is create using the Linux command

zip -P 123123123123123123 test.zip test.txt

I want to unzip it with Java. Because there is no standard API support so I need a third library.

1. I have tried winzipaes, but it prompts that my zip file is not in the AES-256 format.
2. I cannot use sevenzipjbinding, it's too large.

Do you have any suggestion about this? Do you know what algorithm Linux used to encrypt the zip file?

Answer 1

Finally, I done with zip4j.

1. Download zip4j-1.3.1 and import it to project.

2. Sample Code:

   ZipFile zipFile = new ZipFile(YourZipFile);
   if(zipFile.isEncrypted()){
      zipFile.setPassword(Password);
   }
   zipFile.extractAll(Destination);
