Demonstrates how to verify the password for an encrypted or password-protected zip archive. Java

import com.chilkatsoft.*;

public class ChilkatExample {

  static {
    try {
        System.loadLibrary("chilkat");
    } catch (UnsatisfiedLinkError e) {
      System.err.println("Native code library failed to load.\n" + e);
      System.exit(1);
    }
  }

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

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

    CkZip zip = new CkZip();

    // To verify a password for a Zip, the Zip must be opened:
    success = zip.OpenZip("myProtected.zip");
    if (success != true) {
        System.out.println(zip.lastErrorText());
        return;
        }

    // Set the password to be verified:
    zip.put_DecryptPassword("secret");

    boolean passwordOk;
    passwordOk = zip.VerifyPassword();
    if (passwordOk == true) {
        System.out.println("Password is correct.");
        }
    else {
        System.out.println("Password is incorrect.");
        }

    zip.CloseZip();
