介绍

crypto-js是一个前端Javascript标准加密算法库，CryptoJS (crypto.js) 为 JavaScript 提供了各种各样的加密算法。有时候项目涉及到的敏感数据比较多，为了信息安全，我们常常需要对一些数据进行接口加密处理，如编码、将明文转化为暗文、加密比对，目前已支持的算法包括：MD5、 SHA-1、SHA-256、AES、Rabbit、MARC4、HMAC、HMAC-MD5、HMAC-SHA1、HMAC-SHA256、PBKDF2等

各种各样加密算法的js库，安全加密不再愁——crypto-js

安装

使用npm进行安装

npm install crypto-js

使用

支持nodejs和浏览器

 
import sha256 from 'crypto-js/sha256';
import hmacSHA512 from 'crypto-js/hmac-sha512';
import Base64 from 'crypto-js/enc-base64';
 
const message, nonce, path, privateKey; // ...
const hashDigest = sha256(nonce + message);
const hmacDigest = Base64.stringify(hmacSHA512(path + hashDigest, privateKey));

模块化

 
var AES = require("crypto-js/aes");
var SHA256 = require("crypto-js/sha256");
...
console.log(SHA256("Message"));

直接引用

 
<script type="text/javascript" src="path-to/bower_components/crypto-js/crypto-js.js"></script>
<script type="text/javascript">var encrypted = CryptoJS.AES(...);
    var encrypted = CryptoJS.SHA256(...);
</script>

AES加密

明文加密

 
var CryptoJS = require("crypto-js");
 
// Encrypt
var ciphertext = CryptoJS.AES.encrypt('my message', 'secret key 123').toString();
 
// Decrypt
var bytes  = CryptoJS.AES.decrypt(ciphertext, 'secret key 123');
var originalText = bytes.toString(CryptoJS.enc.Utf8);
 
console.log(originalText); // 'my message'

对象加密

 
var CryptoJS = require("crypto-js");
 
var data = [{id: 1}, {id: 2}]
 
// 加密
var ciphertext = CryptoJS.AES.encrypt(JSON.stringify(data), 'secret key 123').toString();
 
// 解密
var bytes  = CryptoJS.AES.decrypt(ciphertext, 'secret key 123');
var decryptedData = JSON.parse(bytes.toString(CryptoJS.enc.Utf8));
 
console.log(decryptedData); // [{id: 1}, {id: 2}]
