Expand description

Security-sensitive features for Endpoint.

Required methods

Establishes a new Connection to a server without verifying the servers Certificate. The servers CertificateChain can still be manually insepcted through Connection::peer_identity.

See connect for more information on host name resolution.


A client certificate KeyPair set with Builder::set_client_key_pair will be ignored, use client_key_pair to add a client certificate to this connection.


Connecting to a server without verifying the Certificate provides no way for the client to authenticate the servers identity. This is primarily used to enable connections to unknown user-hosted servers, e.g. multiplayer.

There are many ways to prevent the need for this feature in certain situations:

  • during testing, a temporary certificate can be created
  • use Let’s Encrypt to get a free certificate if a domain is present
  • provide a middle-man service that helps connect clients with servers by automatically communicating the servers public key
  • share a public key over third-party communication channels beforehand as a last resort
