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

set rsa = Server.CreateObject("Chilkat_9_5_0.Rsa")

' Generate a 1024-bit key.  Chilkat RSA supports
' key sizes ranging from 512 bits to 4096 bits.
success = rsa.GenerateKey(1024)
If (success <> 1) Then
    Response.Write "<pre>" & Server.HTMLEncode( rsa.LastErrorText) & "</pre>"
    Response.End
End If

' Get the private key as unencrypted XML:
keyXml = rsa.ExportPrivateKey()
Response.Write "<pre>" & Server.HTMLEncode( keyXml) & "</pre>"

' To encrypt the key -- meaning to get the key in
' an encrypted PEM format -- load it into a PrivateKey object,
' and then export to encrypted PEM:
set privKey = Server.CreateObject("Chilkat_9_5_0.PrivateKey")

success = privKey.LoadXml(keyXml)
If (success <> 1) Then
    Response.Write "<pre>" & Server.HTMLEncode( privKey.LastErrorText) & "</pre>"
    Response.End
End If

strEncPem = privKey.GetPkcs8EncryptedPem("myPassword")

' You now have the private key in an encrypted format,
' which may be (for example) saved to a database
