Chilkat for the Universal Windows Platform (UWP)

Dim rsa As New Chilkat.Rsa

Dim success As Boolean = rsa.UnlockComponent("Anything for 30-day trial")
If (success <> True) Then
    Debug.WriteLine("RSA component unlock failed")
    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 <> 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.SaveRsaPemFile("privateKey.pem")

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