recipient that the message is from the sender and not from an imposter.
Encryption helps prevent eavesdropping, which occurs when a hacker intercepts and reads your e-mail
messages. Using a cryptographic message format such as S/MIME for encryption helps improve e-mail
privacy because it converts plain, readable text of the message into cipher (scrambled) text. The sender's
messaging program uses the recipient's public key to encrypt (lock) the e-mail message and attachments.
Only the recipient who has the private key that matches the public key you used to encrypt the message can
decipher (unscramble) the message.
A certificate is a digital means of proving your identity. When you send a digitally signed message, you are
sending your certificate and public key. Certificates can expire or be revoked.
NOTE: S/MIME encryption and digital signatures for Windows Mobile-based devices are available only with
Exchange Server 2003 Service Pack 2 or a later version that supports S/MIME. If you aren't using one of
these products, or have not yet synchronized, these options are unavailable.
Digitally sign a message
Digitally signing a message applies your certificate with the public key to the message. This proves to the

Encrypt a message
Encrypting a message protects the privacy of the message by converting it from plain, readable text into
cipher (scrambled) text. Only the recipient who has the private key that matches the public key you used to
encrypt the message can decipher the message.
