JFrame实现批量获取Android安装包安全证书MD5 _安装包

家资是何物，积帙列梁梠。这篇文章主要讲述JFrame实现批量获取Android安装包安全证书MD5相关的知识，希望能为你提供帮助。
今天遇到一个需求。获取全部apk的签名的MD5。以下是我使用java SE实现的一个工具。贴出核心源码。希望给有须要的朋友有所帮助。
界面例如以下：

仅仅须要制定.apk文件所在的文件夹就可以，核心代码例如以下：

public class ReadCmdLine { private static MD5Window window; private static String inputPath; public static void main(String args[]) { window = new MD5Window(); window.setVisible(true); initWindow(); } private static void initWindow() { // 文件文件夹文本框 window.getFilePathButton().addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent arg0) { JFileChooser jfc = new JFileChooser(); jfc.setFileSelectionMode(JFileChooser.FILES_AND_DIRECTORIES); jfc.showDialog(new JLabel(), "选择"); File file = jfc.getSelectedFile(); notDirectoryExcute(file); } }); // 開始运行button window.getBeginButton().addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent arg0) { inputPath = window.getJTextFiled(); if (inputPath != null & & !"".equals(inputPath.trim())) { notDirectoryExcute(new File(inputPath)); } } }); // 清空结果button window.getClearButton().addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent arg0) { window.setTextArea(""); } }); } /** * 推断是否是文件夹，假设不是则运行 * * @param file */ public static void notDirectoryExcute(File file) { if (file.isDirectory()) { inputPath = file.getAbsolutePath(); window.setJTextFiled(inputPath); File[] fiels = file.listFiles(); for (int i = 0; i < fiels.length; i++) { String absPath = fiels[i].getAbsolutePath(); if (absPath.contains(".apk")) { excute(absPath); } } } else { JOptionPane.showMessageDialog(window, "请选择文件夹"); } } /** * 核心逻辑 * * @param absPath */ public static void excute(String absPath) { // 1、从.apk中读取CERT.RSA文件 String appName = absPath.substring(absPath.lastIndexOf("_") + 1, absPath.lastIndexOf(".")); try { if (absPath != null) { readZipFile(absPath); } } catch (Exception e) { e.printStackTrace(); } // 2、运行 keytool命令获取MD5 Process process = null; List< String> processList = new ArrayList< String> (); try { process = Runtime.getRuntime().exec( "keytool -printcert -file D:/test/CERT.RSA"); BufferedReader input = new BufferedReader(new InputStreamReader( process.getInputStream())); String line = ""; while ((line = input.readLine()) != null) { processList.add(line); } input.close(); } catch (IOException e) { e.printStackTrace(); } // 过滤内容 for (String line : processList) { if (line.contains("MD5")) { window.setTextArea(window.getTextArea() + String.format("%-30s", appName) + line.trim() + "\n"); } } } /** * 读取压缩文件内容 * * @param file 压缩文件的路径 * @throws Exception */ public static void readZipFile(String file) throws Exception { ZipFile zf = new ZipFile(file); InputStream in = new BufferedInputStream(new FileInputStream(file)); ZipInputStream zin = new ZipInputStream(in); File outFile = new File("D:\\test\\CERT.RSA"); OutputStream out = new FileOutputStream(outFile); InputStream rsaStream = zf.getInputStream(zf .getEntry("META-INF/CERT.RSA")); byte[] buf1 = new byte[1024]; int len; while ((len = rsaStream.read(buf1)) > 0) { out.write(buf1, 0, len); } rsaStream.close(); out.close(); in.close(); zin.closeEntry(); } }
