VBScript example code showing how to generate an RSA public/private key.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows

Dim fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")
'Create a Unicode (utf-16) output text file.
Set outFile = fso.CreateTextFile("output.txt", True, True)

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

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Rsa")
set rsa = CreateObject("Chilkat.Rsa")

' 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.

If (success <> 1) Then
    outFile.WriteLine(rsa.LastErrorText)
    WScript.Quit
End If

' Keys are exported in XML format:
publicKey = rsa.ExportPublicKey()
outFile.WriteLine(publicKey)

privateKey = rsa.ExportPrivateKey()
outFile.WriteLine(privateKey)
