# Wiretrustee Signal Server

This is a Wiretrustee signal-exchange server and client library to exchange connection information between Wiretrustee Trusted Device and Wiretrustee Hub

The project uses gRPC library and defines service in protobuf file located in:
 ```proto/signal_exchange.proto```

 To build the project you have to do the following things.

Install protobuf version 3 (by default v3 is installed on ubuntu 20.04. On previous versions it is proto 2):

```bash
#!/bin/bash
sudo apt install protoc-gen-go
sudo apt install golang-goprotobuf-dev
```

Generate gRPC code:

```bash
#!/bin/bash
protoc -I proto/ proto/signalexchange.proto --go_out=plugins=grpc:proto
```
