Synopsis: ACME (RFC 8555) client library for Go
Description:

ACMEz is a lightweight, fully-compliant RFC 8555 (ACME) implementation, that provides an API for getting certificates. ACMEz is suitable for large-scale enterprise deployments. It also supports common IETF-standardized ACME extensions.

This module has two primary packages:

  • acmez is a high-level wrapper for getting certificates. It implements the ACME order flow described in RFC 8555 including challenge solving using pluggable solvers.

  • acme is a low-level RFC 8555 implementation that provides the fundamental ACME operations, mainly useful if you have advanced or niche requirements.

Main features:

  • Go API that thoroughly documented with spec citations.

  • Structured error values (problems as defined in RFC 7807.)

  • Smart retries (resilient against network and server hiccups.)

  • Challenge plasticity (randomized challenges, and will retry others if one fails.)

  • Context cancellation (suitable for high-frequency config changes or reloads.)

  • Highly flexible and customizable.

  • External Account Binding (EAB) support.

  • Tested with numerous ACME CAs (more than just Let's Encrypt.)

  • Implements niche aspects of RFC 8555 (such as alt cert chains and account key rollover.)

  • Efficient solving of large SAN lists (e.g. for slow DNS record propagation.)

  • Utility functions for solving challenges: device attestation challenges (draft-acme-device-attest-02), RFC 8737 (tls-alpn-01 challenge), RFC 8823 (email-reply-00 challenge; S/MIME.)

  • ACME Renewal Information (ARI) support (draft-ietf-acme-ari-03.)
