前端使用crypto.js進行加密

npm i crypto-js -S

https://www.npmjs.com/package/crypto-js

key：十六位作爲密鑰（前後端必須一致）
iv：十六位作爲密鑰偏移量（前後端必須一致）
算法：AES/CBC/PKCS7Padding

function getAesString(data,key,iv){//加密
    var key  = CryptoJS.enc.Utf8.parse(key);
    var iv   = CryptoJS.enc.Utf8.parse(iv);
    var encrypted =CryptoJS.AES.encrypt(data,key,
        {
            iv:iv,
            mode:CryptoJS.mode.CBC,
            padding:CryptoJS.pad.Pkcs7
        });
    return encrypted.toString();    //返回的是base64格式的密文
}
function getDAesString(encrypted,key,iv){//解密
    var key  = CryptoJS.enc.Utf8.parse(key);
    var iv   = CryptoJS.enc.Utf8.parse(iv);
    var decrypted =CryptoJS.AES.decrypt(encrypted,key,
        {
            iv:iv,
            mode:CryptoJS.mode.CBC,
            padding:CryptoJS.pad.Pkcs7
        });
    return decrypted.toString(CryptoJS.enc.Utf8);     
}

function getAES(data){ //加密
    var key  = 'AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA';  //密鑰
    var iv   = '1234567812345678';
    var encrypted =getAesString(data,key,iv); //密文
    var encrypted1 =CryptoJS.enc.Utf8.parse(encrypted);
    return encrypted;
}

function getDAes(data){//解密
    var key  = 'AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA';  //密鑰
    var iv   = '1234567812345678';
    var decryptedStr =getDAesString(data,key,iv);
    return decryptedStr;
