Openssl_decryptでJsのcrypto-jsでAES暗号化したテキストを復号できない

久しぶりの投稿になります。

この度、crypto-jsで暗号化したテキストを、PHPで復号しようとしています。
しかしfalseがかってきてしまい、取得で来ていません。

crypto-jsでは↓のJsonで取得しています。
{"ct":"TbmXOUQaoxvjy2eDvQyLTw==","iv":"6dbf44da76d651253ccafb880fe4b152","s":"c153176590f0872b"}

また、コードは下記のように作成しました。

$encoded = 'TbmXOUQaoxvjy2eDvQyLTw==';
$key  = 'c153176590f0872b';
$iv = '6dbf44da76d651253ccafb880fe4b152';
openssl_decrypt($encoded, 'AES-128-CBC', $key, 0, $iv);

上記のopenssl_decryptの結果取得したいテキストはpasspassです。

ご教授いただけますと幸いです。
何卒よろしくお願いいたします。

Jsで行っていること

CryptoJS.AES.encrypt(plaintext, secret(), option).toString();
encrypt: function (cipher, message, key, cfg) {
    // Apply config defaults
    cfg = this.cfg.extend(cfg);

    // Encrypt
    var encryptor = cipher.createEncryptor(key, cfg);
    var ciphertext = encryptor.finalize(message);

    // Shortcut
    var cipherCfg = encryptor.cfg;

    // Create and return serializable cipher params
    return CipherParams.create({
        ciphertext: ciphertext,
        key: key,
        iv: cipherCfg.iv,
        algorithm: cipher,
        mode: cipherCfg.mode,
        padding: cipherCfg.padding,
        blockSize: cipher.blockSize,
        formatter: cfg.format
    });
}

optionの中身

const option = {
        format: {
            stringify(cipherParams) {
                // create json object with ciphertext
                const jsonObj = {
                    ct: cipherParams.ciphertext.toString(CryptoJS.enc.Base64)
                };

                // optionally add iv and salt
                if (cipherParams.iv) {
                    jsonObj.iv = cipherParams.iv.toString();
                }
                if (cipherParams.salt) {
                    jsonObj.s = cipherParams.salt.toString();
                }

                // stringify json object
                return JSON.stringify(jsonObj);
            },
            parse(jsonStr) {
                // parse json string
                const jsonObj = JSON.parse(jsonStr);

                // extract ciphertext from json object, and create cipher params object
                const cipherParams = CryptoJS.lib.CipherParams.create({
                    ciphertext: CryptoJS.enc.Base64.parse(jsonObj.ct)
                });

                // optionally extract iv and salt
                if (jsonObj.iv) {
                    cipherParams.iv = CryptoJS.enc.Hex.parse(jsonObj.iv)
                }
                if (jsonObj.s) {
                    cipherParams.salt = CryptoJS.enc.Hex.parse(jsonObj.s)
                }

                return cipherParams;
            }
        }
    };
