產生license用於驗證認證__java

產生認證放到程式中

FileInputStream fis = new FileInputStream("outputLicense.xml");//輸入FileOutputStream fos = new FileOutputStream("license.enc");//輸出Key key = new EncryptionDecryption().getKey(PASS_PHRASE.getBytes());Cipher cipher = Cipher.getInstance("AES");cipher.init(Cipher.ENCRYPT_MODE, key);cipher.doFinal(PASS_PHRASE.getBytes());//將fis加密儲存到fosCipherOutputStream cos = new CipherOutputStream(fos, cipher);byte[] bytes = new byte[1024];while (true) {int rc = fis.read(bytes);if (rc == -1) {break;}cos.write(bytes, 0, rc);}fis.close();cos.flush();cos.close();fos.close();

登陸或者啟動時檢驗認證

 Key key = new EncryptionDecryption().getKey(PASS_PHRASE.getBytes());            Cipher cipher = Cipher.getInstance("AES");//加密方法            cipher.init(Cipher.DECRYPT_MODE, key);            InputStream is = new FileInputStream(PATH+"license.enc");//加密後的license檔案            CipherInputStream cis = new CipherInputStream(is, cipher);            int offset = 0;            byte[] bytes = new byte[2048];            while (true)            {                int rc = cis.read(bytes, offset, bytes.length - offset);                if (rc == -1)                {                    break;                }                offset += rc;            }            is.close();            cis.close();            //讀入到bean中            Properties licenseProps = new Properties();            licenseProps.loadFromXML(new ByteArrayInputStream(bytes, 0, offset));            license = new License(licenseProps);
