Envío de un mensaje cifrado o con firma digital

A digital signature on an e-mail message helps the recipient verify that you are the authentic sender and not an impostor. Encryption of a message scrambles the message text so that only your intended recipients can read it.

To use digital signatures and encryption, both the sender and recipient must have a mail application that supports the S/MIME standard. Outlook supports the S/MIME standard.
