Description

An ACME client implementation of the ACME protocol (RFC 8555) for OCaml

Published: 21 Mar 2026

README

let's encrypt - an ACME implementation in OCaml

This package contains an implementation of the ACME protocol (mostly client side) purely in OCaml based on RFC 8555. The HTTP, DNS, and ALPN challenges are implemented.

Build with:

    $ opam install letsencrypt
$ opam install letsencrypt-app #for oacmel, the LE client binary

Generate a new account key with:

    $ openssl req -newkey rsa > csr.pem
$ openssl genrsa > account.pem

with OCaml version ≥ 4.07.0. Note: acme.ml is not tested, and should be considered yet to be implemented.
