chrome version 80+, occur this error：

TypeError: Cannot read property '0' of undefined

    at VueComponent.onSubmit (Registry.vue?6ab0:168)

my code is this:

encrypt (word, key, iv) {
      key = key || 'absoietlj32fai12'
      iv = iv || 'absoietlj32fai12'
      let utf8Key = cryptojs.enc.Utf8.parse(key)
      let utf8Iv = cryptojs.enc.Utf8.parse(iv)
      let content = cryptojs.enc.Utf8.parse(word)

      let encrypted = cryptojs.AES.encrypt(content, utf8Key, {
        utf8Iv,
        mode: cryptojs.mode.CBC,
        padding: cryptojs.pad.ZeroPadding
      })
      return encrypted.toString()
    },

i don't kown ,where is wrong in my code?

I am getting the below Error while encrypting the data: TypeError: undefined is not an object (evaluating 'block[i]')

Relevant Code:

const encryptUserData = (userData) => {
    var CryptoJS = require("crypto-js");
    var data = userData;
    var key = CryptoJS.enc.Base64.parse('Secret_key');
    var encrypted = CryptoJS.AES.encrypt(
        data,
        key,
        {
            mode: CryptoJS.mode.CBC,
            padding: CryptoJS.pad.Pkcs7,
        });
    return encrypted.toString();
}

Please help me out to resolve this issue asap. As I need to use AES encryption with PKCS5/PKCS7 padding. Thanks In Advance.

Hi, partner。 By viewing doc of java about AES， which has not support the model of PKCS7，the last， I had used the PKCS5，I'm sorry I couldn't help you。

You left out the property 'iv'. You can try:

let encrypted = cryptojs.AES.encrypt(content, utf8Key, {
        iv: utf8Iv,
        mode: cryptojs.mode.CBC,
        padding: cryptojs.pad.ZeroPadding
})
