Rusty Russell	6f181e0dc1	BOLT update for 8-byte satoshi values, and other updates. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>	8 years ago
Rusty Russell	7389aae26a	Massive BOLT text underscore and formatting updates. This brings us up to 61b5b3f7b4145c9d6d66973b6bfbf28e6c0a0791. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>	8 years ago
Rusty Russell	b99c5620ef	struct secret: use everywhere. We alternated between using a sha256 and using a privkey, but there are numerous places where we have a random 32 bytes which are neither. This fixes many of them (plus, struct privkey is now defined in terms of struct secret). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>	8 years ago
Christian Decker	9820abda7c	sphinx: Store shared secrets on the origin node We could recompute them once we receive a reply and need to decrypt it, but why go through the trouble when we can just store them?	8 years ago
Christian Decker	4a468af378	sphinx: Parameterizing the HMAC size Should have done this a long time ago...	8 years ago
Christian Decker	157c2da778	sphinx: Removing old nexthop based on public keys Signed-off-by: Christian Decker <decker.christian@gmail.com>	8 years ago
Christian Decker	83e89f0fe5	sphinx: Using hop_data to serialize per-hop information into onion Signed-off-by: Christian Decker <decker.christian@gmail.com>	8 years ago
Christian Decker	752f884c23	sphinx: Removed per-hop payloads, will be replaced by hop_data This is in preparation for the migration to `hop_data` which contains all fields, and uses the `short_channel_id` instead of the pubkey.	8 years ago
Christian Decker	bc0039e8c0	sphinx: Onion reply wrapping and unwrapping Signed-off-by: Christian Decker <decker.christian@gmail.com>	8 years ago
Christian Decker	09b31624f0	sphinx: Creating copy of sphinx for new daemon Keeping both the legacy daemon and the new daemon happy with the restructure is a lot of work, so we just don't do it :-)	8 years ago
Rusty Russell	8a84e961ed	daemon/sphinx: support modern v0 hop payload. This just means we put the outgoing_cltv_value where we used to put zeroes. The old daemon simply ignores this, but the new one should check it as per BOLT 4. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>	8 years ago
Rusty Russell	8146b838e8	daemon/sphinx: split handling. We want to use HSM to do the ECDH part, so split that out. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>	8 years ago
Christian Decker	cae283087d	sphinx: Committing the onion packet to the payment-hash The sphinx onion packet now commits to the HTLC payment-hash it is associated with. This prevents replay attacks with the same onion.	8 years ago
Christian Decker	91b17d45d8	sphinx: Removing last vestiges of the end-to-end payload So far this was simply set to a zero-length end-to-end payload. We don't have any plans of re-adding it for the moment, so let's get rid of the unused code.	8 years ago
Rusty Russell	a4fdaab5b3	Use global secp256k1_ctx instead of passing it around. If I'd known how large this patch would be (though trivial), I'd have done it in parts. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>	8 years ago
Rusty Russell	41299b679c	sphinx: process_onionpacket doesn't modify the packet. Make it const. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>	8 years ago
Rusty Russell	8599d63256	sphinx: add brackets around constant definition Always do this, otherwise "MACRO * foo" can have unexpected results. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>	8 years ago
Christian Decker	7bb5c279a8	sphinx: Implemented sphinx onion routing Implements a spec-compliant sphinx onion routing format. The format has been cross-checked with the go implementation cdecker/lightning-onion@b9e117e.	9 years ago
