problem description

since all the code in the front end H5 can be seen in the browser, the AES encrypted key will be exposed, so is it necessary to encrypt ?

the environmental background of the problem

the front end H5 uses AES encryption to transmit data to the background, and the background gets the data through decryption.

related codes

// AES
function aesEncrypt(value){
  var key = "abcdefg"
  var encryptedData = CryptoJS.AES.encrypt(CryptoJS.enc.Utf8.parse(value), CryptoJS.enc.Utf8.parse(key), {
    mode: CryptoJS.mode.ECB,
    padding: CryptoJS.pad.Pkcs7
  });
  return encryptedData.ciphertext.toString();
}
