添加下面的代码,用新的肴杂字典,随机大小写字母组合
- package com.jiuhong.mbtirgtest.util;
- import java.io.FileWriter;
- import java.io.IOException;
- import java.util.HashSet;
- import java.util.Random;
- import java.util.Set;
- public class ObfuscationDictionaryGeneratorUtil {
- public static void generateObfuscationDictionary(String filePath, int count) {
- Set<String> uniqueWords = new HashSet<>(); // 使用 Set 确保唯一性
- while (uniqueWords.size() < count) {
- uniqueWords.add(generateRandomWord(3, 10));
- }
- try (FileWriter writer = new FileWriter(filePath)) {
- for (String word : uniqueWords) {
- writer.write(word + "\n");
- }
- System.out.println("混淆字典已生成: " + filePath);
- } catch (IOException e) {
- System.err.println("生成混淆字典失败: " + e.getMessage());
- }
- }
- private static String generateRandomWord(int minLength, int maxLength) {
- Random random = new Random();
- int wordLength = random.nextInt(maxLength - minLength + 1) + minLength;
- StringBuilder word = new StringBuilder(wordLength);
- for (int i = 0; i < wordLength; i++) {
- char randomChar = (char) (random.nextBoolean() ? 'A' + random.nextInt(26) : 'a' + random.nextInt(26));
- word.append(randomChar);
- }
- return word.toString();
- }
- }
复制代码 生成字典文件
- // 调用方法生成混淆字典
- String filePath = this.getFilesDir().getAbsolutePath() + "/obfuscation_dictionary.txt";
-
- int count = 10000; // 生成 10000 条记录
- ObfuscationDictionaryGeneratorUtil.generateObfuscationDictionary(filePath, count);
复制代码 在Device Explorer找到这个文件
- /data/user/0/com.j.mt/files/obfuscation_dictionary.txt
复制代码 拖到APP目次下
在肴杂文件中添加规则
- #用于字段名和方法名混淆。
- -obfuscationdictionary obfuscation_dictionary.txt
- #用于类名混淆。
- -classobfuscationdictionary obfuscation_dictionary.txt
- #用于包名混淆。
- -packageobfuscationdictionary obfuscation_dictionary.txt
