Within the same window you also have an option 'Create a draft e-mail containing contact information and the Shared Secret' to keep the shared secret either for your reference or for the contact. But, this option is not recommended as the shared secret in draft is not encrypted and if someone gets access to your mail, he will be able to see that easily.

When recipient receives an encrypted mail, he has to provide the correct shared secret, and then Secured email client will decrypt the mail and open it in a Web browser. Instead of using your regular e-mail client, you can also use' Secured eMail Reader' component of the software to read your
encrypted mails.

In case you are not convinced that the mail you are sending is encrypted, here is a simple way that we used while testing the product. Install any protocol analyzer such as WireShark on your machine from which you are sending secured mails and capture all SMTP packets.

Now, when you send an encrypted mail, you can open packets using SMTP protocol along with the title message body. Here, you can easily see that the message body of the mail is encrypted. You can also send a normal mail (without using Secured eMail software) through Outlook and capture SMTP packets. You will be able to read all matter in the message body, whereas earlier when mail was sent using Secured eMail, the message text appeared garbled.

By configuring the Archiving Options of Secured eMail, you can archive all sent and received encrypted messages at a desired location
