Adding secp256k1 support #7

Open infinity0 opened 6 years ago

infinity0 commented 6 years ago

lightning uses noise-with-secp256k1 even though this instantiation is not explicitly mentioned in the noise protocol spec.

Are there any plans to add this to cacophony, or would you be happy to accept a PR implementing such support?

centromere commented 6 years ago

I would accept a PR providing such support.

ovangle commented 6 years ago

Are you OK with secp256k1 from cryptonite lib? If so I could create a PR for that.

centromere commented 6 years ago

Yes. I am OK with that because it doesn't introduce an additional dependency.

I have been working on this. We need to support the custom key rotation mechanism they use in Lightning, but if we do, it will work. I have a PR for secp256k1 support in Cryptonite, let's see if I can get that merged. If I can't, would you be ok with using the ECDH bindings that I could add to secp256k1-haskell? That would require one new dependency then.

centromere commented 5 years ago

Yes.
