Use libsecp256k1 instead of openssl for crypto. We still use openssl for bignums (base58) and for ripemd. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> 2015-06-26 04:24:07 +02:00			`#ifndef LIGHTNING_BITCOIN_PRIVKEY_H`

header cleanup: sort include lines into alpha order, after config.h This makes merging easier in future. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> 2016-01-21 21:08:08 +01:00			`#include "config.h"`

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).
