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

// 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:
Chilkat.SshKey pubkey = new Chilkat.SshKey();

bool success = pubkey.FromOpenSshPublicKey(pubkey.LoadText("qa_data/sshKeys/ssh-keygen/stg.chilkat.id.pub"));
if (success == false) {
    Debug.WriteLine(pubkey.LastErrorText);
    return;
}

Debug.WriteLine(pubkey.LastErrorText);
Debug.WriteLine("Successfully loaded the public key.");

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

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