Java 暴力破解zip压缩包密码

1、引用zip4j包

<dependency><groupId>net.lingala.zip4j</groupId><artifactId>zip4j</artifactId><version>1.3.2</version>
</dependency>

2、获取所有可能的密码集合

package com.yymagicer.util;import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;/*** @ClassName StringUtil* @Description* @Author yangxd* @Date 2021/5/6 16:39* @Version 1.0**/
public class StringUtil {/*** 数字*/public static final String NUMBER = "0123456789";/*** 字母*/public static final String ALPHABET = "abcdefghijklmnopqrstuvwyxz";/*** 符号*/public static final String SYMBOL = "~!@#$%^&*()_+[]{};,.<>?-=";/*** 获取指定的字符** @param includeNumber   是否包含数字* @param includeAlphabet 是否包含字母* @param includeSymbol   是否包含字符* @param length          字符长度* @return*/public static List<String> getStr(boolean includeNumber, boolean includeAlphabet, boolean includeSymbol, int length) {List<String> result = new ArrayList<>();StringBuffer sb = new StringBuffer();if (includeNumber) {sb.append(NUMBER);}if (includeAlphabet) {sb.append(ALPHABET);sb.append(ALPHABET.toUpperCase());}if (includeSymbol) {sb.append(SYMBOL);}if (sb.length() <= length) {result.add(sb.toString());}char[] chars = sb.toString().toCharArray();String[] strings = new String[chars.length];for (int i = 0; i < chars.length; i++) {strings[i] = String.valueOf(chars[i]);}String[] allLists = getAllLists(strings, length);return Arrays.asList(allLists);}/*** 获取指定位数的数据集合** @param elements 基类字符数组* @param length   指定字符串位数* @return*/public static String[] getAllLists(String[] elements, int length) {String[] allLists = new String[(int) Math.pow(elements.length, length)];if (length == 1) {return elements;} else {String[] allSublists = getAllLists(elements, length - 1);int arrayIndex = 0;for (int i = 0; i < elements.length; i++) {for (int j = 0; j < allSublists.length; j++) {allLists[arrayIndex] = elements[i] + allSublists[j];arrayIndex++;}}return allLists;}}/*** 获取全部字符集合，包含数字，字母，特殊字符** @param length* @return*/public static List<String> getFullStr(int length) {return getStr(true, true, true, length);}/*** 获取数字字符集合** @param length* @return*/public static List<String> getNumberStr(int length) {return getStr(true, false, false, length);}/*** 获取字母字符集合** @param length* @return*/public static List<String> getAlphabetStr(int length) {return getStr(false, true, false, length);}/*** 获取特殊符号字符集合** @param length* @return*/public static List<String> getSymbolStr(int length) {return getStr(false, false, true, length);}public static void main(String[] args) {final List<String> str = getNumberStr(4);System.out.println(str.toString());}}

3、解压工具类

package com.yymagicer.util;import net.lingala.zip4j.core.ZipFile;
import net.lingala.zip4j.exception.ZipException;
import net.lingala.zip4j.model.FileHeader;import java.io.File;
import java.io.IOException;
import java.nio.charset.StandardCharsets;
import java.util.ArrayList;
import java.util.List;/*** @ClassName UnZipUtils* @Description* @Author yangxd* @Date 2021/5/7 10:20* @Version 1.0**/
public class UnZipUtils {public static void main(String[] args) throws IOException {String source = "E:\\BaiduNetdiskDownload\\test\\02.zip";String dest = "E:\\BaiduNetdiskDownload\\test";String password = "1234";boolean unZip = unZip(source, dest, password);System.out.println(unZip);}/*** @param source   原始文件路径* @param dest     解压路径* @param password 解压文件密码(可以为空)*/public static boolean unZip(String source, String dest, String password) {try {File zipFile = new File(source);// 首先创建ZipFile指向磁盘上的.zip文件ZipFile zFile = new ZipFile(zipFile);zFile.setFileNameCharset(StandardCharsets.UTF_8.name());// 解压目录File destDir = new File(dest);// 目标目录不存在时，创建该文件夹if (!destDir.exists()) {destDir.mkdirs();}if (zFile.isEncrypted()) {// 设置密码zFile.setPassword(password.toCharArray());}// 将文件抽出到解压目录(解压)zFile.extractAll(dest);List<FileHeader> headerList = zFile.getFileHeaders();List<File> extractedFileList = new ArrayList<>();for (FileHeader fileHeader : headerList) {if (!fileHeader.isDirectory()) {extractedFileList.add(new File(destDir, fileHeader.getFileName()));}}File[] extractedFiles = new File[extractedFileList.size()];extractedFileList.toArray(extractedFiles);for (File f : extractedFileList) {System.out.println(f.getAbsolutePath() + "文件解压成功!");}} catch (ZipException e) {return false;}return true;}
}

4、多线程处理逻辑

package com.yymagicer.core;import java.util.ArrayList;
import java.util.List;/*** @ClassName PasswordCrackService* @Description* @Author yangxd* @Date 2021/5/7 10:01* @Version 1.0**/
public interface PasswordCrackService {Integer THREAD_NUM = 5;String run(String source, String dest);default public List<List<String>> getShardingList(List<String> numberStr) {int num = numberStr.size() / THREAD_NUM;List<List<String>> dataList = new ArrayList<>();int index = 0;int temp = 0;while (temp < numberStr.size()) {temp = (index + 1) * num;dataList.add(numberStr.subList(index * num, temp > numberStr.size() ? numberStr.size() : temp));index++;}return dataList;}
}

package com.yymagicer.core;import com.yymagicer.util.StringUtil;
import com.yymagicer.util.UnZipUtils;
import org.apache.commons.lang3.StringUtils;import java.io.FileWriter;
import java.io.IOException;
import java.util.List;
import java.util.concurrent.*;/*** @ClassName ThreadProcessPasswordCrackServiceImpl* @Description* @Author yangxd* @Date 2021/5/7 13:50* @Version 1.0**/
public class ThreadProcessPasswordCrackServiceImpl implements PasswordCrackService {private ThreadPoolExecutor threadPoolExecutor;public ThreadProcessPasswordCrackServiceImpl() {this.threadPoolExecutor = new ThreadPoolExecutor(4, 20, 60,TimeUnit.SECONDS, new LinkedBlockingQueue<>(), Executors.defaultThreadFactory(),new ThreadPoolExecutor.AbortPolicy());}@Overridepublic String run(String source, String dest) {List<String> numberStr = StringUtil.getNumberStr(6);LinkedBlockingQueue<String> queue = new LinkedBlockingQueue<>();numberStr.forEach(num -> queue.offer(num));long startTime = System.currentTimeMillis();while (!queue.isEmpty()) {threadPoolExecutor.execute(() -> {String name = Thread.currentThread().getName();String key = queue.poll();if (StringUtils.isNotBlank(key)) {boolean result = UnZipUtils.unZip(source, dest, key);if (result) {try (FileWriter fileWriter = new FileWriter(dest + "\\password.txt")) {fileWriter.write(key);System.out.println("线程：" + name + ",密码是：" + key);queue.clear();} catch (IOException e) {e.printStackTrace();}} else {System.out.println("线程：" + name + "," + key + "密码错误");}}});}final long endTime = System.currentTimeMillis();System.out.println("共花费：" + (endTime - startTime) / 1000 + "秒");return null;}
}

5、测试

package com.yymagicer.core;/*** @ClassName Main* @Description* @Author yangxd* @Date 2021/5/7 10:00* @Version 1.0**/
public class Main {public static void main(String[] args) {PasswordCrackService service = new ThreadProcessPasswordCrackServiceImpl();String source = "E:\\BaiduNetdiskDownload\\test\\wzzz.zip";String dest = "E:\\BaiduNetdiskDownload\\test";service.run(source, dest);}
}
