Struct tor_proto::circuit::CircuitBinding
source · pub struct CircuitBinding(/* private fields */);
Expand description
Cryptographic information used to bind a message to a specific circuit.
This information is used in some of our protocols (currently only the onion services protocol) to prove that a given message was referring to a specific hop on a specific circuit, and was not replayed from another circuit.
In tor-spec
and rend-spec
, this value is called KH
.
Implementations§
source§impl CircuitBinding
impl CircuitBinding
sourcepub fn hs_mac(&self) -> HsMacKey<'_>
Available on crate feature hs-service
only.
pub fn hs_mac(&self) -> HsMacKey<'_>
hs-service
only.Return a view of this key suitable for computing the MAC function used to authenticate onion services’ ESTABLISH_INTRODUCE messages.
Note that this is not a general-purpose MAC; please avoid adding new
users of it. See notes on hs_mac
for
more information.
