Send S/MIME Signed and Encrypted Email

Download Chilkat Email ActiveX

Sending a signed and encrypted email is as easy as setting both the SendEncrypted and SendSigned properties. The email is signed using the private key of the sender's certificate, and encrypted using the public key of the recipient's certificate.

' The mailman object is used for sending and receiving email.
set mailman = CreateObject("Chilkat.MailMan2")

' Any string argument automatically begins the 30-day trial.
success = mailman.UnlockComponent("30-day trial")
If (success <> 1) Then
    MsgBox "Component unlock failed"
    WScript.Quit
End If

' Set the SMTP server.
mailman.SmtpHost = "smtp.comcast.net"

' Create a new email object
set email = CreateObject("Chilkat.Email2")

email.Subject = "This email is signed and encrypted"
email.Body = "This is a digitally signed and encrypted mail"
email.From = "Chilkat Support <admin@chilkatsoft.com>"
email.AddTo "Joe","joe@gmail.com"

' To send signed and encrypted email, set both
' SendSigned and SendEncrypted:
email.SendSigned = 1
email.SendEncrypted = 1

success = mailman.SendEmail(email)
If (success <> 1) Then
    MsgBox mailman.LastErrorText
