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

Dim rsa As New Chilkat.Rsa

' Generate a 1024-bit key.  Chilkat RSA supports
' key sizes ranging from 512 bits to 4096 bits.
Dim success As Boolean = rsa.GenerateKey(1024)
If (success <> True) Then
    Debug.WriteLine(rsa.LastErrorText)
    Exit Sub
End If


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

Dim privateKeyXml As String = rsa.ExportPrivateKey()
Debug.WriteLine(privateKeyXml)

' Save the private key in PEM format:
Dim privKey As New Chilkat.PrivateKey
success = privKey.LoadXml(privateKeyXml)
success = privKey.SavePemFile("privateKey.pem")

' Save the public key in PEM format:
Dim pubKey As New Chilkat.PublicKey
success = pubKey.LoadFromString(publicKeyXml)
success = pubKey.SavePemFile(False,"publicKey.pem")
