The use of crypto in the Web

Objective

Crypto is a core module in Nodejs, although there is now a Crypto global object () in the Advanced browser, and its use in Nodejs is different from the web side.

Web-side Use Cryptojs

2. How to use:

• Using encryption methods in Nodejs
  javascript var crypto = require(‘crypto‘); var PRIVATE_KEY = ‘123‘; var hmac = crypto.createHmac(‘sha1‘, private_key); hmac.write(url); hmac.end(); var key = hmac.read().toString(‘base64‘); key = encodeURIComponent(key);
• Switch to web-side use

html <!-- html中代码 --> <!-- 根据上面代码使用引入相应的js --> <script src="cryptojs/rollups/hmac-sha1.js"></script> <script src="cryptojs/components/enc-base64-min.js"></script>

javascript // js中代码 var PRIVATE_KEY = ‘123‘; var hash = CryptoJS.HmacSHA1(url, private_key); var base64 = hash.toString(CryptoJS.enc.Base64); var key = encodeURIComponent(base64);

1. Let's try it yourself!
