cube2.crypto is a small Clojure library for interoperating with Cube 2: Sauerbraten's Auth functionality, based on Elliptic Curve Cryptography.
Morgan Borman has a build of the C++ Sauerbraten library with some useful utility functions here: cube2crypto
Add the following dependency to your project.clj file:
[sauerworld/cube2.crypto "1.0.0"]
(ns auth
(:require [sauerworld.cube2.crypto as crypto]))
;; create private key
(def private-key (crypto/make-privkey)
;; generate public key
(def public-key (crypto/get-pubkey private-key))
;; generate an auth challenge
(def chal (crypto/challenge public-key))
;; generate an answer to the challenge
(def answer (crypto/answer private-key (:challenge chal)))
;; they should match
