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

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.
package com.test;

import android.app.Activity;
import com.chilkatsoft.*;

import android.widget.TextView;
import android.os.Bundle;

public class SimpleActivity extends Activity {

  private static final String TAG = "Chilkat";

  // Called when the activity is first created.
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // 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:
    CkSshKey pubkey = new CkSshKey();

    boolean success = pubkey.FromOpenSshPublicKey(pubkey.loadText("qa_data/sshKeys/ssh-keygen/stg.chilkat.id.pub"));
    if (success == false) {
        Log.i(TAG, pubkey.lastErrorText());
        return;
        }

    Log.i(TAG, pubkey.lastErrorText());
    Log.i(TAG, "Successfully loaded the public key.");

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