Only schnorr related stuff would suffice for now… signatures and verification.
Thanks for the support!

Hey! Did a rough implementation that I think covers your use-case
https://github.com/davidarmstronglewis/k256
alias K256.Schnorr
signing_key = Schnorr.generate_random_signing_key()
message = "This is some content to sign"
assert {:ok, signature} = Schnorr.create_signature(signing_key, message)
assert {:ok, verifying_key} = Schnorr.create_verifying_key(signing_key)
assert :ok = Schnorr.validate_signature(message, signature, verifying_key)
There’s a few things I’m not happy about in this first pass
- I’m not pre-compiling anything for downstream users, that’ll probably be necessary if this is being published to Hex.
signatureandverifying_keyare all lists, but I think people would expect binaries or some other opaque blob. Not sure the best way to do this atm.- Missing specs.
- READMEs are whatever was generated by default, docs are minimal
Let me know your thoughts and if you’d like I can run through anything you’d like to know more about 
Again, not a cryptographer, don’t know much about nostr, but enjoyed the challenge here.

Thanks, I will try this right away and potentially start a nostr lib today, thanks to you!
I Agree about the 4 improvements, in the same order. Binaries would be the best as input.

There is a PR for Secp256k1 Schnorr support natively in an open PR in our Bitcoinex repo here: GitHub - RiverFinancial/bitcoinex: Bitcoin utilities in Elixir · GitHub. We’re working on making the signature and verification primitives work for Nostr.

nostr lib working right here GitHub - RooSoft/nostr: Connect to the nostr network with Elixir · GitHub
Early alpha, but still a great toy to play with…

looks really good so far, love how this collaboratively came together. First time poster on elixir forum (I’ve been read only for a very long time) and it was really lovely to see this play out.
I wonder how much stuff is still needed before being able to go from this library to building an application on top of the protocol?
