Guide to generate proto and certs

Step 1: Proto Generation:

$ cd proto
$ protoc --go_out=plugins=grpc:. *.proto

Step 2: Cert Generation:

$ git clone https://github.com/square/certstrap
$ cd certstrap
$ ./build

$ ./bin/certstrap-master-linux-amd64 init --common-name "akbar.com"
Created out/akbar.com.key
Created out/akbar.com.crt
Created out/akbar.com.crl

$ ./bin/certstrap-master-linux-amd64 request-cert --common-name client
$ ./bin/certstrap-master-linux-amd64 sign out/client --CA akbar.com 

$ ./bin/certstrap-master-linux-amd64 request-cert --common-name server
$ ./bin/certstrap-master-linux-amd64 sign out/server --CA akbar.com

The above files will be generated inside the /out folder

• Copy akbar.com.crt, server.crt and server.key to secure-grpc/server/cert folder
• Copy akbar.com.crt, client.crt and client.key to secure-grpc/client/cert folder

Happy Coding!
