# nuid.elliptic

Cross-platform elliptic curve arithmetic.

Git issues and other communications are warmly welcomed. [[email protected]](mailto:[email protected])

## Requirements

[`jvm`](https://www.java.com/en/download/), [`node + npm`](https://nodejs.org/en/download/), [`clj`](https://clojure.org/guides/getting_started), [`shadow-cljs`](https://shadow-cljs.github.io/docs/UsersGuide.html#_installation)

## Clojure and ClojureScript

### tools.deps:

`{nuid/elliptic {:git/url "https://github.com/nuid/elliptic" :sha "..."}}`

### usage:

```

$ clj # or shadow-cljs node-repl

=> (require '[nuid.elliptic.curve.point :as point])

=> (require '[nuid.elliptic.curve :as curve])

=> (require '[nuid.transit :as transit])

=> (require '[nuid.bn :as bn])

=> (def c (curve/from ::curve/secp256k1))

=> (def g (curve/base c))

=> (def n (curve/order c))

=> (def k (bn/from "123333333333333333333333333333333333333333321"))

=> (def p (point/mul g k))

=> (def q (point/add g p))

```

## Notes

`nuid.elliptic` primarily exists to abstract over platform-specific differences

and provide a common interface to the provided functionality across host

platforms. `nuid.elliptic` delegates directly to host implementions (e.g.

`bouncycastle` on the `jvm`, and `elliptic`, etc., in `node` and the browser).

## Licensing

Apache v2.0 or MIT

## ⚠️  Disclaimer

This library is [property tested](https://github.com/clojure/test.check#testcheck)

to help verify implementation, but has not yet been audited by an independent

third party.
