I want to decrypt the text that in encrypted in php using openssl_encrypt

Question

Php encrypt function is like

 public function encrypt($value)
    {

        $key ="ATob9yt5i9ajBPaw2GkTm8QfkCG9sUnW9cn0ndZmulK=";
        $iv = chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0)
            . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0)
            . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0);
        $d = base64_decode($key);

        $value = \openssl_encrypt($value,
            $this->cipher, $d  , 0,$iv
        );

        return $value;
    }

I have no idea how to decrypt this in js. I'm currently using CryptoJs. The most confusing part is the iv and base64_decode($key).

My current implementation in js is like below

function encrypt(value){

    let key = new Buffer("ATob9yt5i9ajBPaw2GkTm8QfkCG9sUnW9cn0ndZmulK=", 'base64');
    let iv = CryptoJS.enc.Utf8.parse(String.fromCharCode(0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0));

    let encrypted = CryptoJS.AES.encrypt(value,CryptoJS.enc.Utf8.parse(key.toString()), {
        iv:iv,
        mode: CryptoJS.mode.CBC,
    });
}

I'm so confuse with iv key and decoding the key in base64.

The problem is key. It will be resolved if you parse the key with CryptoJS.enc.Base64.parse(key). Base64.parse will transform the key into word array that is what CryptoJS accept as input.
