Generate method should be called when you need to
generate new key to be used with the server. KeyType should be set either to RSAkey or
DSAkey. Old (if any) key loaded in memory will be
destroyed, and new one will take it's place. It is
advised that immediately after new key is generated, you
should Save it to a file for future use.
Generate method can be a lengthy process, especially if
you set large BitCount value
(default BitCount is 1024). It is advised you make random
mouse movements, or type on the keyboard during the keys
generation, to get more random values for new keys.
Possible bitcount values for generating new keys are 768,
1024 (default), 2048 and 3072.
If you with to transfer your existing keys from OpenSSH
(or similar) SSH server, you can easily load such keys
using Load
method. In such case there is no need to generate new pair
of keys.
Important thing is to keep the key private and
unreadable by anyone else except yourself, and the server,
of course. To help you accomplish this, storing generated
keys can optionally be protected using a Password in
Save
method.
Typical scenario to deal with generating/loading/saving
keys would be something like this (sample in VB):
Private Sub Form_Load()
Dim Filename As String
Dim Password As String
' initialize
wodSSHD
Set wodSSHD1 =
New wodSSHDCom
' first we need to
load or generate key we will use
' in productional
systems, generate both keys (RSA/DSA)
' here, just for
the sample, one is enough.
On Error Resume
Next
Filename = App.Path + "\mykey.rsa"
' we don't
need to put password at all - but it's better in real
life
Password = "My
secret password"
' try to load the
key
wodSSHD1.Keys.Load Filename,
Password
If Err <>
0 Then
' load failed - we will generate new
one
wodSSHD1.Keys.Generate
RSAkey
wodSSHD1.Keys.Save
RSAkey, Filename, Password
End
If
' now you can
start the server
End Sub
