SSH to a server from nodejs with ed25519 key

Question

I tried using the module ssh2 by mscdex which, but it doesn't support the key ed25519.

var Connection = require('ssh2');
var c = new Connection();
c.connect({
    host: host,
    port: port, 
    username: user,
    privateKey: require('fs').readFileSync(keyPath)
});

The error is:

node_modules/ssh2/lib/client.js:225                                               
      throw new Error('Cannot parse privateKey: ' + privKeyInfo.message);                      
      ^                                                                                        

Error: Cannot parse privateKey: Unsupported key format                                         
    at Client.connect

I also tried using node-sshpk because I saw that it supports ed25519, but I didn't find a way to connect to the linux server.

Does anyone know a way to connect to the server using ed25519 keys?

Answer 1

There is an open issue in the ssh2 package.

If you want to use the specific ed25519 format, look at the npm package ed25519 .
