(VB.NET) Load SSH Keys Produced by ssh-keygen

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

Chilkat .NET Downloads Chilkat .NET Framework Chilkat for .NET Core

' 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:
Dim pubkey As New Chilkat.SshKey

Dim success As Boolean = pubkey.FromOpenSshPublicKey(pubkey.LoadText("qa_data/sshKeys/ssh-keygen/stg.chilkat.id.pub"))
If (success = False) Then
    Debug.WriteLine(pubkey.LastErrorText)
    Exit Sub
End If


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

' Now try the private key, which contains this:

' -----BEGIN OPENSSH PRIVATE KEY-----
