Review Comment:
Is it better to rename `isHandshaking` to `isSslHandShaking`?

Try this to reduce lines of code and indention
```
if (!isSslMode) return;

Review Comment:
Do we have to allocate a buffer every time we need to decrypt/encrypt data?
Is it possible we allocate (not on heap) 2 large enough buffers for
decryption and encryption to reduce allocation?
