Description

This library implements the ECDH functions 'X25519' and 'X448' as specified in RFC 7748, 'Elliptic curves for security'. In the spirit of the original publications, the public API is kept as simple as possible to make it easy to use and hard to misuse.

The current version is written in plain OCaml, leveraging Zarith for integer arithmetic. While this makes the implementation straightforward and easy to reason about, the performance is nowhere near that of DJB's implementation using floating point registers (https://cr.yp.to/ecdh.html).

README

OCaml-RFC7748

Elliptic curves for cryptographic purposes, based on RFC 7748.

Usage

The API contains documentation. Example use:

open Rfc7748

let _ =
  let priv = X25519.private_key_of_string
      "a546e36bf0527c9d3b16154b82465edd62144c0ac1fc5a18506a2244ba449ac4" in
  let pub = X25519.public_key_of_string
      "e6db6867583030db3594c1a424b15f7c726624ec26b3353b10a903a6d0ab1c4c" in
  X25519.scale priv pub
  |> X25519.string_of_public_key
  |> Printf.printf "c3da55379de9c6908e94ea4df28d084f32eccf03491c71f754b4075577a28552\n == \n%s"

Build status

Results of building rfc7748 with each compiler on check.ci.ocaml.org, run of against opam-repository 8a77e58. All results for this package.

Each result links to its build log. To keep crawlers from overloading the site, build logs require a GitHub sign-in (see ocurrent/opam-health-check). On your first log, GitHub asks you to “Authorize opam-health-check”, the OCurrent app that runs these checks; it sees only your public profile, not your repositories. The sign-in lasts 30 days.
