+# EduVPN shared library
+
+This repository contains a Go library with functions that all EduVPN clients can use. The goal is to let EduVPN clients
+link against this library and gradually merge more common logic between EduVPN clients into this repository.
+
+cgo is used to build the go library into a shared dynamic library. Wrappers will be written using some FFI framework for
+each language used in EduVPN clients to easily interface with the library.
+
+## Functionality
+
+Currently, only verification of signatures on files from `disco.eduvpn.org` is supported. For now, these files have to
+be downloaded by the caller.
+
+## Build & test
+
+Build shared library for current platform:
+
+```shell
+make
+```
+
+Build shared library for specified OS & architecture (example):
+
+```shell
+make OS=windows ARCH=386
+```
+
+Results will be output in `exports/`.
+
+Test Go code:
+
+```shell
+make test-go
+```
+
+Test wrappers:
+
+```shell
+make test-wrappers
+```
+
+Take a look at `wrappers/<lang>/` for descriptions per wrapper.
+
+## Directory
+
+- `verify.go`: main API
+- `verify_test.go` and `test_data/`: tests for API
+- `exports/`: C API interface
+- `wrappers/`: Wrappers per language, currently only C#

+First build the shared Go library. Next:
+
+Build `EduVpnCommon`:
+
+```shell
+make
+```
+
+Build as nupkg, including eduvpn_verify library:
+
+```shell
+make pack
+```
+
+Currently, directly referencing the project may not work if you have multiple dynamic libraries compiled in
+the `exports` folder. If you instead add the `.nupkg`, e.g. with one of the
+methods [here](https://stackoverflow.com/q/43400069) or [here](https://stackoverflow.com/q/10240029) it automatically
+copies the correct library.
+
+Test:
+
+```shell
+make test
+```
