cpace
A Rust implementation of the CPace PAKE, instantiated with the ristretto255 group.
This implementation is based on the go-cpace-ristretto255 implementation by Filippo Valsorda, and attempts to be compatible with it. Note that that implementation is loosely based on draft-haase-cpace-01, so all of these implementations are something of a moving target.
lib.rs
:
An implementation of the CPace Password-Authenticated Key Exchange (PAKE) using Ristretto255. Note that this is an experimental implementation of a draft spec -- don't deploy it until 1.0.
This implementation is based on go-cpace-ristretto255
by Filippo Valsorda.
Example
use rand::rngs::OsRng;
use cpace;
let (init_msg, state) = cpace::init(
"password",
cpace::Context {
initiator_id: "Alice",
responder_id: "Bob",
associated_data: b"",
},
OsRng,
)
.unwrap();
let (bob_key, rsp_msg) = cpace::respond(
init_msg,
"password",
cpace::Context {
initiator_id: "Alice",
responder_id: "Bob",
associated_data: b"",
},
OsRng,
)
.unwrap();
let alice_key = state.recv(rsp_msg).unwrap();
assert_eq!(alice_key.0[..], bob_key.0[..]);
