Java Requires Chilkat v11.0.0+

Unzip an AES Encrypted Text File directly into a String Variable

See more Zip Examples

A common need is to unzip from an AES encrypted Zip archive directly into a string variable, such that the unencrypted file never resides on disk, even temporarily. This example shows how to do it. Chilkat2 Java

import com.chilkatsoft.chilkat2.ChilkatException;
import com.chilkatsoft.chilkat2.Zip;
import com.chilkatsoft.chilkat2.ZipEntry;

public class ChilkatExample {

    public static void main(String[] args) {
        boolean success = false;

        // This example requires the Chilkat API to have been previously unlocked.
        // See Global Unlock Sample for sample code.

        Zip zip = new Zip();

        // This example opens a WinZip-compatible AES encrypted
        // .zip that contains a single file: hamlet.xml.

        // It decrypts and unzips hamlet.xml directly into a string
        // variable.
