_LANGUAGE_ example code showing how to generate an RSA public/private key pair and export to PEM files. VB.NET

Dim success As Boolean = False

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

'  key sizes ranging from 512 bits to 8192 bits.

If (success = False) Then
    Debug.WriteLine(rsa.LastErrorText)

'  Save the private key in PEM format:
