AES / ECB加密<没有iv>

cryptoJS插件(aes加密)前端

// 下载

// “npm install crypto-js”或“yarn add crypto-js”

 

// 基本使用

 

// 引入：

const CryptoJS = require("crypto-js")

 

// 基本使用

const testText = '这是一段要加密的文字' // 文本

const secretKey = "ABCDEFGHIJKL_key" // 密钥（十六位，需要和后端密钥保持一致）

 

// 加密过程

const bytes = CryptoJS.AES.encrypt(

toParse(testText),

toParse(secretKey),

{

mode: CryptoJS.mode.ECB, // 加密模式

padding: CryptoJS.pad.Pkcs7

}

)

 

// 序列化，result即加密结果

const result = CryptoJS.enc.Base64.stringify(bytes.ciphertext)

 

function toParse(val) {

return CryptoJS.enc.Utf8.parse(val)

}
