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. C#

bool success = false;

//  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();

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-----
