Dim rsa As New ChilkatRsa

Dim success As Long
success = rsa.UnlockComponent("Anything for 30-day trial")
If (success <> 1) Then
    Text1.Text = Text1.Text & rsa.LastErrorText & vbCrLf
    Exit Sub
End If

'  Generate a 1024-bit key.  Chilkat RSA supports
'  key sizes ranging from 512 bits to 4096 bits.
success = rsa.GenerateKey(1024)
If (success <> 1) Then
    Text1.Text = Text1.Text & rsa.LastErrorText & vbCrLf
    Exit Sub
End If

'  Get the private key as unencrypted XML:
Dim keyXml As String
keyXml = rsa.ExportPrivateKey()
Text1.Text = Text1.Text & keyXml & vbCrLf

'  To encrypt the key -- meaning to get the key in
'  an encrypted PEM format -- load it into a PrivateKey object,
'  and then export to encrypted PEM:
Dim privKey As New PrivateKey

success = privKey.LoadXml(keyXml)
If (success <> 1) Then
    Text1.Text = Text1.Text & privKey.LastErrorText & vbCrLf
    Exit Sub
End If

Dim strEncPem As String

strEncPem = privKey.GetPkcs8EncryptedPem("myPassword")

'  You now have the private key in an encrypted format,
'  which may be (for example) saved to a database.
