Secure RPC with TLS/SSL

• Client: Single request
• Server: Single response

Generate code

protoc -I . --go_out=plugins=grpc:. proto/center.proto

Generate server key and certificate

• server.key: a private RSA key to sign and authenticate the public key
• server.crt: self-signed X.509 public keys for distribution

openssl req -new -x509 -days 365 -sha256 -newkey rsa:2048 -nodes \
    -keyout "server.key" -out "server.crt" \
    -subj "/emailAddress=admin@devplayg.com/CN=devplayg.com/OU=Cert/O=Devplayg/L=Pangyo/ST=Sungnam/C=KR"

Run server

go run server/main.go

Run client

Secure
