> Hello Artur, we currently don't expose the `HandshakeContext` outside of the `QuicTLSEngineImpl`. The `HandshakeContext` is what is needed to get the relevant user specified algorithm constraints. So I decided to let the `HandshakeContext` be an internal detail in `QuicTLSEngineImpl` and introduce the `getAlgorithmConstraints()` method on it. Do you think we should hand out the `HandshakeContext` outside of `QuicTLSEngineImpl`?

Hi Jaikiran! Sounds good. It's likely we are going to re-work this code anyhow when we make QUIC engine public in the next iteration. We had a discussion with Daniel about it today.
