Native Email Encryption

[RFH Reseller: InspireUK]

I want to send email using a personal email certificate. I'm currently using the Persits CryptoManager and MailSender via classic ASP but it is not an idea situation and i'd much rather package it all up with the rest of my site in .Net.

Has anyone else done this or got any ideas.

Thanks,

I've tried the code below.

   Dim CM As ASPENCRYPTLib.ICryptoManager
   CM = New ASPENCRYPTLib.CryptoManager()
   Dim Mail As ASPEMAILLib.IMailSender
   Mail = New ASPEMAILLib.MailSender()
   Dim strSubject As String
   Dim strFrom As String
   Dim strTo As String
   Dim strBody As String
   Dim cert As String
   strSubject = "Test"
   strFrom = "josh@test.com"
   strTo = "josh@test.com"
   strBody = "test123"
   cert = "secureemail.cer"
   Dim Context As ASPENCRYPTLib.ICryptoContext = CM.OpenContext("SecureMail", True)
   Dim RecipientCert As ASPENCRYPTLib.ICryptoCert = CM.ImportCertFromFile(Server.MapPath(cert))
   Dim Msg As ASPENCRYPTLib.ICryptoMessage = Context.CreateMessage
   Msg.AddRecipientCert(RecipientCert) ' repeat if necessary
   '' Send Encrypted Message
   Mail.Host = "mail.test.com"
   Mail.Username = "josh@test.com"
   Mail.Password = "test"
   Mail.Subject = strSubject
   Mail.From = strFrom
   Mail.FromName = strFrom
   Mail.AddAddress(strTo)
   Mail.Body = strBody
   Mail.IsHTML = True
   Mail.SendEncrypted(Msg) ' Use CryptoMessage object

But I get "System.Security.SecurityException: System.Security.Permissions.SecurityPermission" when defining CM = New ASPENCRYPTLib.CryptoManager()

Any ideas?

You will not be able to call ActiveX/Com controls from .NET code running under Medium Trust.

Any .Net alternatives?
