QUIC transport constructor fails with ed25519 keys

[vyzo]

Trying to bring up some relays using ed25519 keys, and I run into this:

May 01 18:14:27 ip-172-31-47-2 relay.sh[13132]: 2019/05/01 18:14:27 transport constructor github.com/libp2p/go-libp2p-quic-transport.NewTransport failed: unsupported key type for TLS

[vyzo]

So basically we can't use QUIC with ed25519 keys.

[Stebalien]

We need to switch to the new TLS handshake, IIRC.

[vyzo]

Is there a quic(k) remedy for this so that we can use it now?

[Stebalien]

Not really.

I've just added a PR: #65

But it requires Go1.13

[Kubuxu]

Yeah, we need to wait for Go1.13 as they've just introduced ed25519 support in TLS and included ed25519 in the standard library.

[marten-seemann]

We should probably rather reuse the code from the TLS package (see #18). In addition to code reuse, this will allow us to use all key types. Unfortunately, since QUIC doesn't have a separate net.Conn per connection, this is not trivial though.

I've added a comment in the PR: #65 (comment)
