About this fingerprint
A hash of the QUIC transport parameters a client offers: which parameters it sends and the values it picks for flow-control limits, idle timeout and connection IDs. Parameter order and GREASE values are normalised before hashing. Two clients with the same TLS stack but different QUIC libraries usually differ here.
