 Go package edkey allows you to marshal/write ED25519 private keys
 in the OpenSSH private key format.
 .
 Example:
 .
   package main
 .
   import (
       "crypto/rand"
       "encoding/pem"
       "io/ioutil"
       "github.com/mikesmitty/edkey"
       "golang.org/x/crypto/ed25519"
       "golang.org/x/crypto/ssh"
   )
 .
   func main() {
       // Generate a new private/public keypair for OpenSSH
       pubKey, privKey, _ := ed25519.GenerateKey(rand.Reader)
       publicKey, _ := ssh.NewPublicKey(pubKey)
 .
       pemKey := &pem.Block{
           Type: "OPENSSH PRIVATE KEY",
           Bytes: edkey.MarshalED25519PrivateKey(privKey),
       }
       privateKey := pem.EncodeToMemory(pemKey)
       authorizedKey := ssh.MarshalAuthorizedKey(publicKey)
 .
       _ = ioutil.WriteFile("id_ed25519", privateKey, 0600)
       _ = ioutil.WriteFile("id_ed25519.pub", authorizedKey, 0644)
   }
