Jireh程序猿的那些事

SSLContext Kickstart 是一个库，它提供了一个高级 SSLFactory 类，用于配置 http 客户端以通过 SSL/TLS 进行通信，以进行单向身份验证或双向身份验证。通过最小化外部依赖性，它被设计为尽可能轻量级。核心库仅依赖于 SLF4J 日志 API。

我是用在Netty支持wss协议，需要从本地路径读取pem格式的cert和key，生成SSLContext在netty中使用。网上找了下netty的支持使用都是比较传统的用法，也没有发现pem格式的SSLContext生成用例，所以特意找到了这个类库，发现还不错，才记录并分享下。

相关用法

基础

import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;
import org.json.JSONException;
import org.json.JSONObject;

import nl.altindag.ssl.SSLFactory;

public class App {

    public static void main(String[] args) throws IOException, JSONException {
        SSLFactory sslFactory = SSLFactory.builder()
                .withDefaultTrustMaterial()
                .build();

        HttpClient httpClient = HttpClients.custom()
                .setSSLContext(sslFactory.getSslContext())
                .setSSLHostnameVerifier(sslFactory.getHostnameVerifier())
                .build();

        HttpGet request = new HttpGet("https://api.chucknorris.io/jokes/random");

        HttpResponse response = httpClient.execute(request);
        String chuckNorrisJoke = new JSONObject(EntityUtils.toString(response.getEntity())).getString("value");

        System.out.println(String.format("Received the following status code: %d", response.getStatusLine().getStatusCode()));
        System.out.println(String.format("Received the following joke: %s", chuckNorrisJoke));
    }

}

PEM

从类路径加载pem文件

X509ExtendedKeyManager keyManager = PemUtils.loadIdentityMaterial("certificate.pem", "private-key.pem");
X509ExtendedTrustManager trustManager = PemUtils.loadTrustMaterial("some-trusted-certificate.pem");

SSLFactory.builder()
          .withIdentityMaterial(keyManager)
          .withTrustMaterial(trustManager)
          .build();

netty wss demo

@Override
	protected void initChannel(NioSocketChannel ch) {
		ChannelPipeline pipeline = ch.pipeline();

		if (isWss) {
			X509ExtendedKeyManager keyManager = PemUtils.loadIdentityMaterial(Paths.get("/www/server/panel/vhost/cert/pioneer.ouhaihr.com/fullchain.pem"),
				Paths.get("/www/server/panel/vhost/cert/pioneer.ouhaihr.com/privkey.pem"));

			SSLFactory sslFactory = SSLFactory.builder()
				.withIdentityMaterial(keyManager)
				.build();

			SSLEngine engine = sslFactory.getSslContext().createSSLEngine();
			engine.setUseClientMode(false);
			engine.setNeedClientAuth(false);
			pipeline.addLast(new SslHandler(engine));
		}

		// 处理第一次连接http的握手请求
		pipeline.addLast(new HttpServerCodec());
		// 写文件内容
		pipeline.addLast(new ChunkedWriteHandler());
		// 保证接收的http请求的完整性
		pipeline.addLast(new HttpObjectAggregator(maxContentLength));
		// 处理其他的WebSocketFrame
		pipeline.addLast(new WebSocketServerProtocolHandler(websocketPath));
		// 空闲检测
		ch.pipeline().addLast(new MyIdleStateHandler());
		// WebSocket数据包编解码器
		ch.pipeline().addLast(webSocketPacketCodec);
		// 添加tcp/websocket通用handler
		pipelineUtil.addHandler(pipeline);
	}
