js代码

var CryptoJS = require("crypto-js");function jslencode(text) {var aes_key = "397151C04723421F"var key = CryptoJS.enc.Utf8.parse(aes_key);var iv = CryptoJS.enc.Utf8.parse("");var srcs = CryptoJS.enc.Utf8.parse(text);var encrypted = CryptoJS.AES.encrypt(srcs, key, {iv: iv,mode: CryptoJS.mode.ECB,padding: CryptoJS.pad.Pkcs7});return encrypted.ciphertext.toString(CryptoJS.enc.Hex)
}
//console.log(jslencode('123123'));
