介紹

crypto-js是一個(gè)前端Javascript標(biāo)準(zhǔn)加密算法庫，CryptoJS (crypto.js) 為 JavaScript 提供了各種各樣的加密算法。有時(shí)候項(xiàng)目涉及到的敏感數(shù)據(jù)比較多，為了信息安全，我們常常需要對(duì)一些數(shù)據(jù)進(jìn)行接口加密處理，如編碼、將明文轉(zhuǎn)化為暗文、加密比對(duì)，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

安裝

使用npm進(jìn)行安裝

npm install crypto-js

使用

支持nodejs和瀏覽器

ES6

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));

模塊化

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');// Encryptvar ciphertext = CryptoJS.AES.encrypt('my message', 'secret key 123').toString();// Decryptvar bytes = CryptoJS.AES.decrypt(ciphertext, 'secret key 123');var originalText = bytes.toString(CryptoJS.enc.Utf8);console.log(originalText); // 'my message'

對(duì)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}]
