If you by default treat every GitHub repo as quality production code unless explicitly mentioned otherwise, you're in for a bad time.
First person compared it to WireGuard, next person said yeah but it's probably for education, and I'm saying yeah but I think it's fair to compare it to WireGuard since the README doesn't make it clear whether it's a toy or a production tool.
And if you compare it to WireGuard then it becomes clear you shouldn't use this thing if you want real encryption.
