acme2

一个基于Tokio和OpenSSL的ACMEv2客户端。

特性

• 支持ACME v2，已针对Let's Encrypt和Pebble进行测试
• 完全异步，使用reqwest / Tokio
• 支持DNS01和HTTP01验证
• 完全使用tracing进行仪表化

示例

此示例演示了如何使用http-01验证为example.com域名配置证书。

use acme2::gen_rsa_private_key;
use acme2::AccountBuilder;
use acme2::AuthorizationStatus;
use acme2::ChallengeStatus;
use acme2::DirectoryBuilder;
use acme2::Error;
use acme2::OrderBuilder;
use acme2::OrderStatus;
use acme2::Csr;
use std::time::Duration;

const LETS_ENCRYPT_URL: &'static str =
  "https://acme-v02.api.letsencrypt.org/directory";

#[tokio::main]
async fn main() -> Result<(), Error> {
  // Create a new ACMEv2 directory for Let's Encrypt.
  let dir = DirectoryBuilder::new(LETS_ENCRYPT_URL.to_string())
    .build()
    .await?;

  // Create an ACME account to use for the order. For production
  // purposes, you should keep the account (and private key), so
  // you can renew your certificate easily.
  let mut builder = AccountBuilder::new(dir.clone());
  builder.contact(vec!["mailto:[email protected]".to_string()]);
  builder.terms_of_service_agreed(true);
  let account = builder.build().await?;

  // Create a new order for a specific domain name.
  let mut builder = OrderBuilder::new(account);
  builder.add_dns_identifier("example.com".to_string());
  let order = builder.build().await?;

  // Get the list of needed authorizations for this order.
  let authorizations = order.authorizations().await?;
  for auth in authorizations {
    // Get an http-01 challenge for this authorization (or panic
    // if it doesn't exist).
    let challenge = auth.get_challenge("http-01").unwrap();

    // At this point in time, you must configure your webserver to serve
    // a file at `https://example.com/.well-known/${challenge.token}`
    // with the content of `challenge.key_authorization()??`.

    // Start the validation of the challenge.
    let challenge = challenge.validate().await?;

    // Poll the challenge every 5 seconds until it is in either the
    // `valid` or `invalid` state.
    let challenge = challenge.wait_done(Duration::from_secs(5), 3).await?;

    assert_eq!(challenge.status, ChallengeStatus::Valid);

    // You can now remove the challenge file hosted on your webserver.

    // Poll the authorization every 5 seconds until it is in either the
    // `valid` or `invalid` state.
    let authorization = auth.wait_done(Duration::from_secs(5), 3).await?;
    assert_eq!(authorization.status, AuthorizationStatus::Valid)
  }

  // Poll the order every 5 seconds until it is in either the
  // `ready` or `invalid` state. Ready means that it is now ready
  // for finalization (certificate creation).
  let order = order.wait_ready(Duration::from_secs(5), 3).await?;

  assert_eq!(order.status, OrderStatus::Ready);

  // Generate an RSA private key for the certificate.
  let pkey = gen_rsa_private_key(4096)?;

  // Create a certificate signing request for the order, and request
  // the certificate.
  let order = order.finalize(Csr::Automatic(pkey)).await?;

  // Poll the order every 5 seconds until it is in either the
  // `valid` or `invalid` state. Valid means that the certificate
  // has been provisioned, and is now ready for download.
  let order = order.wait_done(Duration::from_secs(5), 3).await?;

  assert_eq!(order.status, OrderStatus::Valid);

  // Download the certificate, and panic if it doesn't exist.
  let cert = order.certificate().await?.unwrap();
  assert!(cert.len() > 1);

  Ok(())
}

开发

要运行测试，您需要安装pebble和pebble-challtestsrv。

在运行以下命令之前启动这些服务（在不同的shell中）

pebble -config ./pebble-config.json -strict

pebble-challtestsrv

Windows

在Windows上编译需要OpenSSL。以下是安装它的简单方法。

(Git Bash中的示例)

git clone https://github.com/microsoft/vcpkg
cd vcpkg
./bootstrap-vcpkg.sh
./vcpkg.exe install openssl
./vcpkg.exe install openssl:x64-windows-static
# Add OPENSSL_DIR=/vcpkg/path/installed/x64-windows-static
cargo build
