instant-acme: async, pure-Rust ACME client

Documentation Crates.io Build status License: Apache 2.0

instant-acme is an async, pure-Rust ACME (RFC 8555) client.

instant-acme is used in production at Instant Domains to help us provision TLS certificates within seconds for our customers. instant-acme relies on Tokio and rustls to implement the RFC 8555 specification.

Features

  • Store/recover your account credentials by serializing/deserializing
  • Fully async implementation with tracing support
  • Support for processing multiple orders concurrently
  • Support for external account binding
  • Support for certificate revocation
  • Uses hyper with rustls and Tokio for HTTP requests
  • Uses ring for ECDSA signing
  • Minimum supported Rust version: 1.63

Limitations

  • Only tested with DNS challenges against Let's Encrypt (staging and production) and ZeroSSL (production) so far
  • Only supports ECDSA keys for now

Getting started
