' This example assumes the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

Dim rsa As New ChilkatRsa

' Generate a 1024-bit key.  Chilkat RSA supports
' key sizes ranging from 512 bits to 4096 bits.
' Note: Starting in Chilkat v9.5.0.49, RSA key sizes can be up to 8192 bits.
' It takes a considerable amount of time and processing power to generate
' an 8192-bit key.
Dim success As Long
success = rsa.GenerateKey(1024)
If (success <> 1) Then
    Debug.Print rsa.LastErrorText
    Exit Sub
End If

' Keys are exported in XML format:
Dim publicKey As String
publicKey = rsa.ExportPublicKey()
Debug.Print publicKey

Dim privateKey As String
privateKey = rsa.ExportPrivateKey()
Debug.Print privateKey
