Authentication Example

Overview

SSL is a commonly used cryptographic protocol to provide end-to-end communication security. In the example, we show how to set up a server authenticated SSL connection to transmit RPC.

We provide grpc::SslServerCredentials and grpc::SslCredentials types to use SSL conections.

In our example, we use the public/private keys created ahead:

• "localhost.crt" contains the server certificate (public key).
• "localhost.key" contains the server private key.
• "root.crt" contains the certificate (certificate authority) that can verify the server's certificate.

Try it!

Once you have working gRPC, you can build this example using either bazel or cmake. Make sure to run those at this directory so that they can read credential files properly.

Run the server, which will listen on port 50051:

$ ./ssl_server

Run the client (in a different terminal):

$ ./ssl_client

If things go smoothly, you will see the client output:
