I socialize on terminal
# build
make deps
make dev
# generate certs
./hack/tls.sh
# run engine
./engine.out# run client
./cli.out "addr:port" number | cert location
# ex) ./cli.out "127.0.0.1:3001" tls/sub1.crt.pem
# it is also possible to login as admin specified in config.json
# at endpoint ${addr}:3000
# using command below
# gencert
# : generates client cert
# - data: client id
