proto: Add UnverifiedRelayChannel implementation

2025-11-19T19:42:47Z

This commits takes out the relay specific code out of UnverifiedChannel and puts it in UnverifiedRelayChannel. In order to pull this off, we added some fiels to the VerifiedChannel struct so the relay code get back generated data from the UnverifiedChannel::check() in order to do its validation work and yield a VerifiedRelayChannel. This also lead to a cleanup of expect() and ChannelType::is_initiator(). Signed-off-by: David Goulet

proto: Compute authenticate data after validating certificates

2025-10-23T17:46:24Z

This is only done if we kept the AUTH_CHALLENGE cell and we have relay identities. In other words, this is only when the UnverifiedChannel was created from a RelayInitiatorHandshake. Note: The check_internal() function is too large and should be refactored in smaller pieces. Note: It is also likely that we need to split UnverifiedChannel and VerifiedChannel as it is getting client or relay members. Not great. Signed-off-by: David Goulet

proto: Add a relay channel builder

2025-10-23T17:45:41Z

The client and relay channel builder don't share anything and return different objects hence the seperation. Furthermore, this seperation avoids having the client ChanMgr ability to launch relay channels. Signed-off-by: David Goulet

proto: Add RelayIdentities object holding our keys

2025-10-23T17:45:41Z

This is a intermediary object between tor-chanmgr and tor-proto that is when building a relay channel, those keys/certs need to be set in the ChannelBuilder so the tor-proto can use them to authenticate. We avoid that way making tor-proto depending on tor-keymgr for the ultimate goal to avoid tor-proto to have access to all the keys in the KeyMgr. Future commits will introduce a relay channel builder which will use that object to set the keys. Signed-off-by: David Goulet

proto: Add RelayInitiatorHandshake

2025-10-23T17:44:42Z

This implements the relay initiator side of the handshake up to the creation of an unverified channel. Signed-off-by: David Goulet
