zx2c4: I've looked at the Go version on your homepage, but the initial text in the git project. "This is not a complete implementation of WireGuard ..... There is no group of users that should use the code in this repository here under any circumstances at the moment, not even beta testers or dare devils.", is this the one that you refer to or do you have a closed git project with a newer version?
Either way. The L2TP/IPSec implementation in Windows 7 I use now is also closed-source proprietary software. So I can't see that TunSafe should be worse since the author is public. I guess TunSafe will not be able to communicate with the wireguard servers if it does not use the correct encryption and protocol scheme?
