这段SM4加密混淆代码该怎样处理？

下面的混淆代码，在本地调试时类似卡死状态，很久之后，提示内存不足，然后浏览器崩溃。用万能的AI分析，说是有环境检测，死循环，还有push类的不断增加内存损耗的玩意。而这些代码，真正有效的任务就是进行SM4的加密。让AI给处理，发现处理和没处理一个样，各种报错不断。肯请平台上的高手，给出修改并且本地调试不报错，并能正确出结果的代码。学艺不精，不要见笑。

感谢大神！也感谢楼上的几位大神的热情帮助！ysp半步给的上述代码删除结尾的<i>后，替换掉中间的<i>为后，结果一下子就出来了！很激动。回头我再研究一下那个key是怎么获取的。抱着大神的小腿，很幸福，虽然自己水平不怎么样，但跟着你们学习，乐趣还是很大的。
