Dim success As Boolean = 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:
Dim pubkey As ChilkatSshKey
pubkey.Initialize

success = pubkey.FromOpenSshPublicKey(pubkey.LoadText("qa_data/sshKeys/ssh-keygen/stg.chilkat.id.pub"))
If success = False Then
    Log(pubkey.LastErrorText)
    Return
End If


Log(pubkey.LastErrorText)
Log("Successfully loaded the public key.")

'  Now try the private key, which contains this:

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