npm install crypto-js
要用 AES 算法加密氧猬，首先我們要引入 crypto-js 撇寞，crypto-js 是一個純 javascript 寫的加密算法類庫 祭饭，可以非常方便地在 javascript 進(jìn)行 MD5、SHA1游沿、SHA2乡小、SHA3、RIPEMD-160 哈希散列奢啥，進(jìn)行 AES秸仙、DES、Rabbit桩盲、RC4筋栋、Triple DES 加解密

demo1

// 加載核心加密庫
var CryptoJS = require("crypto-js");
// 加載des算法
var tripledes = require("crypto-js/tripledes");
// 開始加密，并且返回密文
var ciphertext  = tripledes.encrypt("fuckyou", '123').toString();
// 解密
var plaintext  = tripledes.decrypt(ciphertext, '123').toString(CryptoJS.enc.Utf8)
// 輸出密文和解密后的內(nèi)容
console.log(ciphertext, plaintext)

demo2 DES加密

// 加載核心加密庫
var CryptoJS = require("crypto-js");

function encrypt (message, key) {
    var keyHex = CryptoJS.enc.Utf8.parse(key);
     var encrypted = CryptoJS.DES.encrypt(message, keyHex, {
        mode: CryptoJS.mode.ECB,
        padding: CryptoJS.pad.Pkcs7
    });
    return {
        key: keyHex,
        value: encrypted.toString()
    }
}

function decrypt (message, key) {
    var plaintext = CryptoJS.DES.decrypt(message, key, {
        mode: CryptoJS.mode.ECB,
        padding: CryptoJS.pad.Pkcs7
    })
    return plaintext.toString(CryptoJS.enc.Utf8)
}

var a = encrypt('mssage123', '123');
var b = decrypt(a.value, a.key);

console.log(a.value.length)

demo3 AES加密

const CryptoJS = require('crypto-js');  //引用AES源碼js
    
    const key = CryptoJS.enc.Utf8.parse("1234123412ABCDEF");  //十六位十六進(jìn)制數(shù)作為密鑰
    const iv = CryptoJS.enc.Utf8.parse('ABCDEF1234123412');   //十六位十六進(jìn)制數(shù)作為密鑰偏移量
    
    //解密方法
    function Decrypt(word) {
        let encryptedHexStr = CryptoJS.enc.Hex.parse(word);
        let srcs = CryptoJS.enc.Base64.stringify(encryptedHexStr);
        let decrypt = CryptoJS.AES.decrypt(srcs, key, { iv: iv, mode: CryptoJS.mode.CBC, padding: CryptoJS.pad.Pkcs7 });
        let decryptedStr = decrypt.toString(CryptoJS.enc.Utf8);
        return decryptedStr.toString();
    }
    
    //加密方法
    function Encrypt(word) {
        let srcs = CryptoJS.enc.Utf8.parse(word);
        let encrypted = CryptoJS.AES.encrypt(srcs, key, { iv: iv, mode: CryptoJS.mode.CBC, padding: CryptoJS.pad.Pkcs7 });
        return encrypted.ciphertext.toString().toUpperCase();
    }
    
    export default {
        Decrypt ,
        Encrypt
    }
