安装
npm install crypto-js --save-dev
npm install md5 --save-dev
1.一些常见的built-in 函数加密
unescape
unescape() 函数可对通过 escape() 编码的字符串进行解码。
let e = escape("始識") console.log(e) // %u59CB%u8B58 let u = unescape(e) console.log(u) // 始識
URL编码与解码
let e = encodeURI("https://始識的博客") console.log(e) // https://%E5%A7%8B%E8%AD%98%E7%9A%84%E5%8D%9A%E5%AE%A2 let u = decodeURI(e) console.log(u) // https://始識的博客
fromCharCode
将 Unicode 编码转为一个字符
var n = String.fromCharCode(65); // A [101,118,97,108].map(item=>{ return String.fromCharCode(item) }) ['e', 'v', 'a', 'l']
2.Base64
btoa atob
let e = btoa("https://www.cnblogs.com/zichliang/p/17265960.html") console.log(e) let u = atob(e) console.log(u)
引用 crypto-js 加密模块

12.RSA
使用 node-rsa
需要安装一个库

使用自带模块crypto
const crypto = require('crypto'); const nodeRSA = require('node-rsa'); // 生成一个1024长度的密钥对 const key = new nodeRSA({b: 1024}); // 导出公钥 const publicKey = key.exportKey('public'); // 导出私钥 const privateKey = key.exportKey('private'); const secret = 'https://www.cnblogs.com/zichliang/p/16653303.html' // 使用私钥加密,公钥解密 const encrypt = crypto.privateEncrypt(privateKey, Buffer.from(secret)); const decrypt = crypto.publicDecrypt(publicKey, encrypt); console.log('加密后:', encrypt.toString('base64')); console.log('解密后:', decrypt.toString());
13.RSA 长加密
这个加密是真的麻烦 ,而且还需要导入jsencrypt.min.js
var encrypt = new JSEncrypt(); var publickKey = "-----BEGIN PUBLIC KEY----- MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDLFb8qp1vRFvi/qfgi1Wg7Mi8l LcpfAc+tgpyD7aFW9QquQVMm/jG1IJZVQ6LsdkI7TiDutMCzOMCBXbdSC9BCIAGA L2Sz3cYVlGb1kYSM0ZMcUMIK5eF4Bptke070XHvbi8wArtysJ0l71RHDd786tNbG W0hDSw3zAqTErbxFaQIDAQAB -----END PUBLIC KEY----- " encrypt.setPublicKey(publickKey); //设置公钥加密证书 var data = "https://www.cnblogs.com/zichliang/p/17265960.html"; var commonEncodeData = encrypt.encryptLong(data); // 普通的加密 console.log(commonEncodeData) var cnEscapeData = window.btoa(window.encodeURIComponent(data)); //base64 解密后的加密 var encryptData = encrypt.encryptLong(cnEscapeData); //获取加密后数据。 console.log(encryptData)
