Play with Finite Field in OCaml

This library provides functors to instantiate finite field of arbitrary orders (in the limit of Zarith, the dependency to handle arbitrary integers).

module F13 = Ff.MakeFp (struct let prime_order = Z.of_string "13" end)
module BLSFr = Ff.MakeFp (
  struct
    let prime_order = Z.of_string "52435875175126190479447740508185965837690552500527637822603658699938581184513"
  end
)

JavaScript compatibility

This library can be transpiled in JavaScript using js_of_ocaml. An example is provided in js/test_js.ml, with the corresponding dune file. It instantiates Fp with p = 53. dune will compile this into a FiniteField.js file, exporting methods like add, toString, random, etc. FiniteField can be used as a Node module. See js/test/test_js.js for an example.

# Generate FiniteField.js
dune build js
cp _build/default/js/FiniteField.js ./
node
var FF = require("./FiniteField.js");
let x = FF.random();
let y = FF.random();
let x_plus_y = FF.add(x, y);
