clj-secp256k1

A Clojure library that defines a wrapper around secp256k1-kmp. As secp256k1-kmp, we try to follow as much of the original secp256k1 lib as possible.

Extra functions that can be helpful on the day-to-day can the added to the clj-secp256k1.utils namespace.

Contributions for new functions and documentation are welcome.

Usage

(ns example.core
  (:require [clj-secp256k1.secp256k1 :as secp256k1]
            [clj-secp256k1.utils.hex :as utils.hex]
            [clj-secp256k1.utils.sha256 :as utils.sha256]))

(def some-secret-key "c90fdaa22168c234c4c6628b80dc1cd129024e088a67cc74020bbea63b14e5c9")
(def some-public-key "dd308afec5777e13121fa72b9cc1b7cc0139715309b086c960e18fd969774eb8")

(defn -main
  []
  (let [message      (-> (utils.sha256/generate "message that will be signed")
                         utils.hex/decode)
        secret-key   (utils.hex/decode some-secret-key)
        public-key   (utils.hex/decode some-public-key)
        aux-rand32   (utils.hex/decode some-aux-rand32)
        sig          (secp256k1/sign-schnorr message secret-key aux-rand32)]
