example-grpc

Example of an authenticated gRPC & grpc-gateway HTTP server, and various client connection examples.

Setting up

1. Install Go 1.21 from https://golang.org/
2. Run make compile to compile the server & client code.

Running the server

make run-server

Running the clients

1. make run-client runs a gRPC client that sends a token-authenticated request to the gRPC endpoint.

2. make run-client-alice runs a gRPC client that sends a mTLS request to the gRPC endpoint using Alice's certificate & key.

3. make run-client-bob runs a gRPC client that sends a mTLS request to the gRPC endpoint using Bob's certificate & key. It will fail since Bob's certificate is not permitted.

4. make run-curl invokes curl to send a token-authenticated request to the HTTP server.

5. make run-curl-alice invokes curl to send a mTLS request to the HTTP server using Alice's certificate & key.

6. make run-curl-bob invokes curl to send a mTLS request to the HTTP server using Bob's certificate & key. It will fail since Bob's certificate is not permitted.

7. make run-grpcurl invokes grpcurl to send a token-authenticated request to the gRPC server.

8. make run-grpcurl-alice invokes grpcurl to send a mTLS request to the gRPC server using Alice's certificate & key.

9. make run-grpcurl-bob invokes grpcurl to send a mTLS request to the gRPC server using Bob's certificate & key. It will fail since Bob's certificate is not permitted.
