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

Dim pkey As New Chilkat.PrivateKey
Dim rsa As New Chilkat.Rsa
rsa.GenKey(1024,pkey)
rsa.UsePrivateKey(pkey)

Dim strData As String = "This is the string to be signed."

' Get the signature in base64url
rsa.EncodingMode = "base64url"
Dim strSig As String = rsa.SignStringENC(strData,"sha256")

Debug.WriteLine(strSig)
