This is an interoperable Go implementation of libschannel. It is intended for small embedded systems (and their counterpart server programs) for which a full-fledged PKI is unnecessary; most people will want to use a mutally-authenticated TLS-secured TCP connection.

GoDoc: go-schannel

It provides bi-directional secure channels over an insecure communications channel (in this case, a Go io.ReadWriter).

This program is dual licensed. You may choose either the public domain license or the ISC license; the intent is to provide maximum freedom of use to the end user.
