Grpc Java:在服务器上设置SSLContext

我想在我的GRPC服务器上设置SSL。 为此,我需要证书链和pkcs8私钥。

我已经执行以下操作:

生成CA密钥:

openssl genrsa -des3 -out ca.key 4096

生成CA证书:

openssl req -new -x509 -days 365 -key ca.key -out ca.crt

生成服务器密钥:

openssl genrsa -des3 -out server.key 4096

生成服务器签名请求:

openssl req-新-key server.key -out server.csr

自签名服务器证书:

openssl x509 -req -days 365 -in server.csr -CA ca.crt -CAkey ca.key -set_serial 01 -out server.crt

从服务器密钥中删除密码短语:

openssl rsa -in server.key -out server.key

转换为pkcs8

openssl pkcs8 -topk8 -nocrypt-输入server.key -out pkcs8_key.pem


现在我有了我的 server.cert pkcs8_key.pem 文件,我已经这样创建了服务器:

InputStream certChain = MyServer.class.getResourceAsStream("/server.crt");
        InputStream privateKey = MyServer.class.getResourceAsStream("/pkcs8_key.pem");
        SslContext sslContext = GrpcSslContexts.forServer(certChain, privateKey, "password").build();


        Server server = NettyServerBuilder.forPort(8080)
                            .sslContext(sslContext)
                            .addService(new ChatService())
                            .addService(new HelloWorldService())
                            .useTransportSecurity(certChain, privateKey)
                            .build();

类路径已正确配置。

我得到的错误堆栈:

答案 0 :(得分:0)

此行引起了异常:

SslContext sslContext = GrpcSslContexts
    .forServer(certChain, privateKey, "password").build();

由于您的pkcs8密钥没有密码,因此您不应传递密码,而应使用两种参数的方法:

SslContext sslContext = GrpcSslContexts
    .forServer(certChain, privateKey).build();

请注意,呼叫useTransportSecurity()将覆盖对sslContext()的呼叫,因此您不应该同时呼叫这两个呼叫。调用两者都将在当前代码中中断,因为forServer()将消耗并关闭提供的InputStream,因此您需要将关闭的流传递给useTransportSecurity()
