Spring / Spring gRPC Interview Questions

How do you enable TLS for a gRPC server in a Spring Boot application?

TLS is configured by supplying certificate and private key material to the server's SSL context. With the community starter this is typically done through properties such as:

grpc:
  server:
    security:
      enabled: true
      certificate-chain: file:server.crt
      private-key: file:server.key

Under the hood these settings are wired into the embedded Netty server's SslContext, so the gRPC channel negotiates TLS the same way any HTTP/2-over-TLS server would - clients then connect using a TLS-capable channel (rather than plaintext) and validate the server's certificate as part of the connection handshake.

What kind of material must be supplied to enable TLS on a Spring gRPC server?
What underlying component's SslContext do these TLS properties typically configure?
