Load SSH Keys Produced by ssh-keygen

See more SSH Key Examples

Demonstrates how to load the public and private keys produced by ssh-keygen. Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // This example assumes the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  // We first generate a key like this:

  //     ssh-keygen -f stg.chilkat.id
  //     Generating public/private rsa key pair.
  //     Enter passphrase (empty for no passphrase):
  //     Enter same passphrase again:
  //     Your identification has been saved in stg.chilkat.id.
  //     Your public key has been saved in stg.chilkat.id.pub.
  //     The key fingerprint is:
  //     SHA256:hkbgexkspxYTa8rYUxouRU8Gi7lbbsT6dSLX+JlStKk me@example02240
  //     The key's randomart image is:
  //     +---[RSA 2048]----+
  //     |  o.=            |
  //     | + * =           |
  //     |o + X =          |
  //     | O * O.+         |
  //     |+ @ +.=oS        |
  //     | A o =+.         |
  //     |o + =oo          |
  //     | o +E+ o         |
  //     |  .  .+          |
  //     +----[SHA256]-----+

  // 

  // The public key (generated to the file stg.chilkat.id.pub) contains this:
  // ssh-rsa AAAAB3NzaC1yc2EAAAADAQABA.. FDt+dKJEkhw8I7LpEi17diB9 me@example02240

  // First let's load the public key:
  final pubkey = CkSshKey();

  try {
    pubkey.fromOpenSshPublicKey(pubkey.loadText('qa_data/sshKeys/ssh-keygen/stg.chilkat.id.pub'));
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  print(pubkey.lastErrorText);
  print('Successfully loaded the public key.');

  // Now try the private key, which contains this:

  // -----BEGIN OPENSSH PRIVATE KEY-----
