npm:ssh2 times out waiting for handshake

[GJZwiers]

npm:ssh2 does not work in Deno right now, it hangs for a bit and then throws.

import { Client } from "npm:ssh2";

const client = new Client();
client.on("ready", () => {
  console.log("Client :: ready");
  client.exec("uptime", (err, stream) => {
    if (err) throw err;
    stream.on("close", (code, signal) => {
      console.log("Stream :: close :: code: " + code + ", signal: " + signal);
      client.end();
    }).on("data", (data) => {
      console.log("STDOUT: " + data);
    }).stderr.on("data", (data) => {
      console.log("STDERR: " + data);
    });
  });
}).connect({
  host: "<some_ip>",
  port: 22,
  username: "<some_user>",
  privateKey: Deno.readFileSync(/path/to/my/key.pem"),
});

error: Uncaught Error: Timed out while waiting for handshake

It looks like ssh2 uses a number of methods from Node crypto that are not implemented in std yet:

• createDecipheriv
• createDiffieHellman
• createDiffieHellmanGroup
• createECDH,
• createHmac
• createPublicKey
• createSign
• createVerify
• diffieHellman
• generateKeyPairSync
• sign
• verify

Deno version: 1.28.0
