Throw an exception if you don't like the peer's key. Default impl checks the key size against minimum_rsa_bits, minimum_ecdsa_group_size, or minimum_ecdh_group_size depending on the key's type. Override if you'd like to perform some other kind of test on (or logging of) the peer's keys.

Select a key exchange group to use, from the list of groups sent by the peer. In TLS 1.3 handshakes the peer might have provided cryptographic material for a subset of its available groups. Choosing a group for which no share was provided will result in an additional round trip. If none are acceptable, return Group_Params::NONE.
By default this will try to optimize for less round trips even if this results in the usage of a less preferred group.

If this function returns false, unknown PSK identifiers will be rejected with an unknown_psk_identifier alert as soon as the non-existence is identified. Otherwise, a false identifier value will be used and the protocol allowed to proceed, causing the handshake to eventually fail without revealing that the username does not exist on this system.
