mmkvWithID 这个函数里面，cryptKey 超过16字节会怎么样

[zeus1024]

@param cryptKey The encryption key of the MMKV instance (no more than 16 bytes).

16字节应该是16个英文字母，如果超过了会怎么样，我自己测试，不会报错
会截断？

It's will get truncated.
The underlying encryption algorithm is AES 256, 256 for 256 bit. Hence the 16 bytes limit.

MMKV v2.3.0 provides AES-256 key length. http://github.com/Tencent/mmkv/releases/tag/v2.3.0
