* | proto: Add the verify_link_auth_cert() helperDavid Goulet2026-03-192-2/+58
| | | | | | | | | | | | The responder channel will soon use it. Signed-off-by: David Goulet <[email protected]>
* | proto: Use RelayIds in a VerifiedChannelDavid Goulet2026-03-195-64/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to pull this off, make UnverifiedChannel::check_relay_identities() to return a RelayIds that it builds after checking if they match the peer we were expecting. This part is moved in this commit so once check_relay_identities() returns, we are certain of the relay identity validity on both "it identified properly" and "it is the right expected relay". This makes it that the check_relay_identities() returns the RelayIds, the signing key and the RSA id digest (which is needed for authentication later). Signed-off-by: David Goulet <[email protected]>
* | proto: Move into a helper function the TLS cert validationDavid Goulet2026-03-191-28/+61
| | | | | | | | | | | | | | | | | | | | This introduces verify_tls_cert() standalone function. It is such because both client and relay initiator will use it. For now, the check_internal() has been modified to use it. We are slowly building towards having specialized check function per channel type. Signed-off-by: David Goulet <[email protected]>
* | proto: Split relay identity checks from CERTS into its own functionDavid Goulet2026-03-191-90/+109
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a loaded commit, apologize in advance but not many way around this. One thing that is generic to all verifiable channel (authenticated) is that they all need to check the relay identities and signing key from the CERTS cell. This commits extracts that part into UnverifiedChannel::check_relay_identities() which returns those said identities and the signing key (KP_relaysign_ed). The signing key is actually needed for only one context, the initiator part because the TLS cert is signed with it. The LINK AUTH cert is signed by the ed25519 identity key itself which is what the responder will look for. This commit has two side effects which I believe are OK: 1. The timeliness check of the identity certs is now done prior to the other cert (TLS/LINK). 2. We no longer check signatures in batch mode as we can't batch ed25519 sig check with the RSA crosscert sig. It appears the batch validation was there for performance and not for security purposes. The end goal of this piece of work is that the specialized channel will start by calling a generic check function that will call check_relay_identities(). And then, the secondary certificates will get checked depending on the side of the channel. Expect also a variable rename commit at the end as the naming in this function is really bad.

* | proto: Extract inline helpers into struct itselfDavid Goulet2026-03-191-40/+46
|/ | | | | | | | | | | Move two inline functions located in UnverifiedChannel::check_internal() into the UnverifiedChannel object itself. Laying down the ground work for the more specialized objects to use those as the check_internal() is about to get massively refactored into more specific channel types.

* tor-proto: send an AUTH_CHALLENGE during testsSteven Engler2026-03-031-0/+2
| | | | | | | As far as I know, a responder will always send an AUTH_CHALLENGE cell since it doesn't yet know if the initiator is a client or relay. The spec also doesn't have any mention about the AUTH_CHALLENGE being optional. So we should send it in our tests as well.

* proto: Channel handshake minor cleanupDavid Goulet2026-03-033-11/+12
| | | | | | | | | | To make the code a bit better here. Also, at this commit, the UnverifiedChannel::finish() and VerifiedChannel::finish() are basically the exact same. A refactoring to use a finish() helper would work nicely. Signed-off-by: David Goulet <[email protected]>

| | | | | | | | | | | Every specific types know if the peer is sensitive or not so now the finish() of each of these channel types builds the right PeerInfo with MaybeSensitive.

* tor-proto: split field into two fieldsSteven Engler2026-02-242-7/+11
| | | | | These were previously in a single `Option`, but now that the `Option` was removed, I think it's nicer to make these separate fields.
