From 18c7d3f157957a5c8034e165d0fc09490c25b0ba Mon Sep 17 00:00:00 2001 From: Nick Mathewson Date: Tue, 4 Dec 2012 21:39:54 -0500 Subject: Rename handshake_digest to rend_circ_nonce The handshake_digest field was never meaningfully a digest *of* the handshake, but rather is a digest *from* the handshake that we exapted to prevent replays of ESTABLISH_INTRO cells. The ntor handshake will generate it as more key material rather than taking it from any part of the circuit handshake reply.. --- src/or/rendmid.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'src/or/rendmid.c') diff --git a/src/or/rendmid.c b/src/or/rendmid.c index dc2dc1d9e7..8234265ca5 100644 --- a/src/or/rendmid.c +++ b/src/or/rendmid.c @@ -56,8 +56,8 @@ rend_mid_establish_intro(or_circuit_t *circ, const uint8_t *request, goto err; } - /* Next 20 bytes: Hash of handshake_digest | "INTRODUCE" */ - memcpy(buf, circ->handshake_digest, DIGEST_LEN); + /* Next 20 bytes: Hash of rend_circ_nonce | "INTRODUCE" */ + memcpy(buf, circ->rend_circ_nonce, DIGEST_LEN); memcpy(buf+DIGEST_LEN, "INTRODUCE", 9); if (crypto_digest(expected_digest, buf, DIGEST_LEN+9) < 0) { log_warn(LD_BUG, "Internal error computing digest."); -- cgit v1.2.3-54-g00ecf
