' 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 = Server.CreateObject("Chilkat.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

' Keys are exported in XML format:
publicKeyXml = rsa.ExportPublicKey()
Response.Write "<pre>" & Server.HTMLEncode( publicKeyXml) & "</pre>"

privateKeyXml = rsa.ExportPrivateKey()
Response.Write "<pre>" & Server.HTMLEncode( privateKeyXml) & "</pre>"

' Save the private key in PEM format:
' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.PrivateKey")
set privKey = Server.CreateObject("Chilkat.PrivateKey")
success = privKey.LoadXml(privateKeyXml)
success = privKey.SavePemFile("privateKey.pem")

' Save the public key in PEM format:
' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.PublicKey")
set pubKey = Server.CreateObject("Chilkat.PublicKey")
success = pubKey.LoadFromString(publicKeyXml)
success = pubKey.SavePemFile(0,"publicKey.pem")
