How to unzip a file folder which have password security?

Question

i am unzipping a folder using the following code:

var zipFilePath="D:\\readytodelete\\folder\\Test.zip";
var unzipPath="D:\\readytodelete\\folder";
var zipFile = null;

try {
   zipFile = new java.util.zip.ZipFile(zipFilePath);
   var entries = zipFile.entries();
   var bytes = new Packages.java.lang.reflect.Array.newInstance(java.lang.Byte.TYPE, 1024);
   
   while (entries.hasMoreElements()) {
      var zipEntry = new java.util.zip.ZipEntry(entries.nextElement());
      var fileFromZipEntry = new java.io.File(unzipPath + java.io.File.separator + zipEntry.getName());
      
      //zipEntry reports / as separator, even on Windows, so we're not using java.io.File.separator in the following test
      if (StringUtils.endsWith(zipEntry.getName(), '/')) {
         fileFromZipEntry.mkdirs();
         continue;
      } else {
         var inputStream = null;
         var outputStream = null;
         var length = -1;
         
         try {
            inputStream = zipFile.getInputStream(zipEntry);
            outputStream = new java.io.FileOutputStream(fileFromZipEntry);
            
            while ((length = inputStream.read(bytes)) >= 0) {
               outputStream.write(bytes, 0, length);
            }
         } finally {
            if (inputStream !== null) {
               inputStream.close();
               inputStream = null;
            }
            
            if (outputStream !== null) {
               outputStream.close();
               outputStream = null;
            }
         }
      }
   }
} catch (err) {
   qie.error('Failed to unzip file \'' + zipFilePath + '\': ' + err);
} finally {
   if (zipFile !== null) {
      zipFile.close();
      zipFile = null;
   }
}

and this code is working fine now i want to unzip a foder which need passcode before to unzip so what are the required modification i need to do in mapping script? 

please send me the requierd mapping script.

It sounds like adding a password to a zip file is not natively available in Java, but could be accomplished using some 3rd party libraries.  https://stackoverflow.com/questions/10587561/password-protected-zip-file-in-java

You can include the jars by adding external libraries: https://www.qvera.com/kb/index.php/256/what-are-external-libraries-or-jar-files
