Working example with SSH and libgit2/git2go

SSHwithgit2go.go

package main

// Made this one just return 0 during troubleshooting...
func certificateCheckCallback(cert *git.Certificate, valid bool, hostname string) git.ErrorCode {

}

func main() {

  cloneOptions := &git.CloneOptions{}
  // use FetchOptions instead of directly RemoteCallbacks
  // https://github.com/libgit2/git2go/commit/36e0a256fe79f87447bb730fda53e5cbc90eb47c
