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

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");}
