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%u8B58let 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%A2let 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)

11.Rabbit
// 引用 crypto-js 加密模块var CryptoJS = require('crypto-js') function rabbitEncrypt() { return CryptoJS.Rabbit.encrypt(text, key).toString();} function rabbitDecrypt() { return CryptoJS.Rabbit.decrypt(encryptedData, key).toString(CryptoJS.enc.Utf8);} var text = "https://www.cnblogs.com/zichliang/p/16653303.html"var key = "1234567ASDFG" var encryptedData = rabbitEncrypt()var decryptedData = rabbitDecrypt() console.log("加密字符串: ", encryptedData)console.log("解密字符串: ", decryptedData) // 加密字符串: U2FsdGVkX1/pYbHvbNff3/RNpso4yRKIX0XDFta8hoLNxe52K8HSmF+XV8ayYqucTKVPP6AJtGczXS7U9kkxHnw=// 解密字符串: https://www.cnblogs.com/zichliang/p/16653303.html
12.RSA
使用 node-rsa
需要安装一个库
npm install node-rsa
// 引用 node-rsa 加密模块var NodeRSA = require('node-rsa'); function rsaEncrypt() { pubKey = new NodeRSA(publicKey,'pkcs8-public'); var encryptedData = pubKey.encrypt(text, 'base64'); return encryptedData} function rsaDecrypt() { priKey = new NodeRSA(privatekey,'pkcs8-private'); var decryptedData = priKey.decrypt(encryptedData, 'utf8'); return decryptedData} var key = new NodeRSA({b: 512}); //生成512位秘钥var publicKey = key.exportKey('pkcs8-public'); //导出公钥var privatekey = key.exportKey('pkcs8-private'); //导出私钥var text = "https://www.cnblogs.com/zichliang/p/16653303.html" var encryptedData = rsaEncrypt()var decryptedData = rsaDecrypt() console.log("公钥:\n", publicKey)console.log("私钥:\n", privatekey)console.log("加密字符串: ", encryptedData)console.log("解密字符串: ", decryptedData)
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)
