S/MIME-protected message basics

About signing and encrypting messages
You can digitally sign or encrypt messages to add another level of security to email messages and PIN messages that you send from your
BlackBerry® device. Digital signatures are designed to help recipients verify the authenticity and integrity of messages that you send.
When you digitally sign a message using your private key, recipients use your public key to verify that the message is from you and that
the message has not been changed.
Encryption is designed to keep messages confidential. When you encrypt a message, your device uses the recipient's public key to encrypt
the message. Recipients use their private key to decrypt the message.
To send an encrypted PIN message, you must have a PIN and an email address for the contact in your contact list. Your device uses the
email address in your contact list to locate a PGP® key or certificate for the contact.
