cryptojs如何加密大数据

使用crypto.js对大数据进行加密，具体方法以下：

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'; //密钥
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'; //密钥
var iv = '1234567812345678';
var decryptedStr =getDAesString(data,key,iv);
return decryptedStr;
}
