Individually sign and encrypt a message
Encrypting an Outlook e-mail message protects the privacy of
the message by converting it from plain, readable text into cipher
(scrambled) text. Only the recipient who has the authorisation key can
decipher the message.
Digitally signing a message applies your certificate with the
authorisation key to the message. This proves to the recipient that the
message is from you and not from an imposter or a hacker, and that
the message has not been altered.
