Question

我正在尝试通过GRPC-SSL将Java客户端连接到非Java服务器。我可以在不使用SSL时连接到服务器。当我尝试使用SSL上下文（使用提供的pem文件）创建ManagedChannel时，我得到以下异常（相同的pem文件适用于NodeJS客户端）。

ManagedChannel channel = NettyChannelBuilder.forAddress("localhost", 10010)
    .sslContext(GrpcSslContexts.forClient().trustManager(new File("./test/myprivkey.pem")).build())
    .build();

来自trustManager调用的异常：

build.gradle相关部分

compile 'io.netty:netty-tcnative-boringssl-static:1.1.33.Fork26'

任何想法可能导致问题或如何进一步解决这个问题？

Answer 1

我正在读取错误的文件作为构建SslContext的证书文件。用正确的证书文件替换错误的输入解决了问题。

Answer 2

如果您的证书来自DNSSimple，我发现我需要这样做 openssl pkcs8 -topk8 -nocrypt -in original.key -out new_key.key.pcks8 转换密钥的格式。：（
