An async, user-friendly Let's Encrypt/ACMEv2 library written in Rust.

The API and implementation were inspired by [acme2][], [acme-micro][], and [lego][].

## Features
- ACME v2 ([RFC 8555][])
- Register with CA
- Obtain certificates
- Renew certificates
- Revoke certificates
- Robust implementation of ACME challenges
  - [HTTP][] (http-01)
  - [DNS][] (dns-01)
- SAN certificate support
- Custom challenge solvers ([`Solver` trait][])
- [External account bindings][]

### Missing features

- [ ] [TLS-ALPN-01][] challenge implementation
- [ ] Certificate bundling

Contributions are welcome for any of the above features.
