crypto.js加密传输
前端页面

后台：
/** * DES解密 * * @param secretData * 密码字符串 * @param secretKey * 解密密钥 * @return 原始字符串 * @throws Exception */ public String decryption(String secretData, String secretKey) throws Exception { // DES算法要求有一个可信任的随机数源 SecureRandom random = new SecureRandom(); // 创建一个DESKeySpec对象 DESKeySpec desKey = new DESKeySpec(secretKey.getBytes("UTF-8")); // 创建一个密匙工厂 SecretKeyFactory keyFactory = SecretKeyFactory.getInstance("DES"); // 将DESKeySpec对象转换成SecretKey对象 SecretKey securekey = keyFactory.generateSecret(desKey); // Cipher对象实际完成解密操作 Cipher cipher = Cipher.getInstance("DES"); // 用密匙初始化Cipher对象 cipher.init(Cipher.DECRYPT_MODE, securekey, random); // 真正开始解密操作 return IOUtils.toString(cipher.doFinal(Base64.decodeBase64(secretData.getBytes())),"UTF-8"); }
调用：
System.out.println("=========" + decryption("tzZ2WRdJ32o=", "12345678"));
注意密匙需要八位以上的所以这里用了1到8，密匙可以自定义
