(VBScript) Generate RSA Key and return Base64 PKCS8 Private Key
Demonstrates how to generate a new 2048-bit RSA private key and returns the Base64 encoded PKCS8 representation of the private key. Note: This example requires Chilkat v11.0.0 or greater.
Dim fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")
'Create a Unicode (utf-16) output text file.
Set outFile = fso.CreateTextFile("output.txt", True, True)
success = 0
set rsa = CreateObject("Chilkat.Rsa")
' Generate a 2048-bit key. Chilkat RSA supports
' key sizes ranging from 512 bits to 8192 bits.
set privKey = CreateObject("Chilkat.PrivateKey")
success = rsa.GenKey(2048,privKey)
If (success = 0) Then
outFile.WriteLine(rsa.LastErrorText)
WScript.Quit
End If
' Get the private key in PKCS8 Base64 format
privKeyPkcs8Base64 = privKey.GetPkcs8ENC("base64")
' The key in base64 format will start similar to this:
' MIIEvAIBADANBgkqhkiG9w0BA...
outFile.WriteLine(privKeyPkcs8Base64)
outFile.Close
