推荐答案
您想要什么？
您需要更具体些。
What do you want?
You need to be more specific.
有大量的CRC16算法，每种算法都有自己的多项式，并且有特定的用途。有些CRC16算法非常适合创建散列（例如，对于Redis而言），而其他算法则更适合于有线通信。
There is a huge plethora of CRC16 algorithms, each one with its own polynomial and for a specific use. Some CRC16 algorithms are really good to create hashes ( for Redis, for example ) while others are better for wire communication.

如果这是您要走的路，那么GitHub和NPM可以为您提供许多实现。
If this is the road you want to go with, then GitHub and NPM have many implementations that could work for you.
他们的文档通常非常可怕或不存在，不能保证它们会像广告中所宣传的那样工作，但是如果有任何更改，您可以随时尝试一下，并且如果您发现错误，可以随时在其问题页面中报告。
Their documentation is usually downright horrible or non-existent and there is no guarantee they will work as advertised, but if anything goes, you can always give them a try, and if you find a bug you can always report it in their issues page.
这是我发现的快速实现，应该是您所需要的：
Here is a quick implementation I found, should be what you need:
