Rusty Russell	8340d8c070	secret_eq: remove in favor of constant time variant. ... To be safe, we should never memcmp secrets. We don't do this currently outside tests, but we're about to. The tests to prove this as constant time are the tricky bit. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>	2018-08-23 14:46:22 +02:00
Rusty Russell	5d815238cf	common/derive_basepoints: complete the set of single-value derive functions. ... This helps make it explicit what we're deriving; these two were missing. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>	2018-07-24 00:40:01 +02:00
Rusty Russell	64008e275a	common/derive_basepoints: add routines to get a specific secret. ... Often we only need a single secret, so it's clearer to have routines to do just that. When we change to the lnd key scheme, there will be no benefit in calculating them all together. This also adds a test! Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>	2018-07-17 12:32:00 +02:00
