DES加密解密-CryptoJS与Java

前端页面在往后台传递某些敏感数据时需要对数据进行加密，以提高安全性。但需要注意的是，前端加密和后端解密的算法应该保持一致，才能确保功能能正常使用，废话不多说直接上码。

CryptoJS

CryptoJS 点击这里

function encryptByDES(message, key) { var keyHex = CryptoJS.enc.Utf8.parse(key); var encrypted = CryptoJS.DES.encrypt(message, keyHex, { mode: CryptoJS.mode.ECB, padding: CryptoJS.pad.Pkcs7 }); return encrypted.toString(); } function decryptByDES(ciphertext, key) { var keyHex = CryptoJS.enc.Utf8.parse(key); var decrypted = CryptoJS.DES.decrypt({ ciphertext: CryptoJS.enc.Base64.parse(ciphertext) }, keyHex, { mode: CryptoJS.mode.ECB, padding: CryptoJS.pad.Pkcs7 }); return decrypted.toString(CryptoJS.enc.Utf8); }

Java

/** * DES加密 * @param datasource * @return */ public String encode(String datasource){ try{ SecureRandom random = new SecureRandom(); DESKeySpec desKey = new DESKeySpec(KEY.getBytes(CODE_TYPE)); //创建一个密匙工厂，然后用它把DESKeySpec转换成 SecretKeyFactory keyFactory = SecretKeyFactory.getInstance("DES"); SecretKey securekey = keyFactory.generateSecret(desKey); //Cipher对象实际完成加密操作 Cipher cipher = Cipher.getInstance("DES"); //用密匙初始化Cipher对象 cipher.init(Cipher.ENCRYPT_MODE, securekey, random); //现在，获取数据并加密 byte[] temp = Base64.encodeBase64(cipher.doFinal(datasource.getBytes())); return IOUtils.toString(temp,"UTF-8"); }catch(Throwable e){ e.printStackTrace(); return null; } } /** * DES解密 * @return */ public String decode(String src) 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(KEY.getBytes(CODE_TYPE)); // 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(src)),"UTF-8"); }
