About digital signatures and
encryption
You can digitally sign a message to help the recipient
verify the authenticity and integrity of the message.
When you digitally sign a message using your private
key, the recipient uses your public key to verify that
you sent the message and not someone who was
pretending to be you, and that no one has changed the
message before it arrived.
You can encrypt a message to keep the message
confidential. When you encrypt a message, your
BlackBerry® device uses the recipient's public key to
encrypt the message. Only the recipient's private key
can decrypt the message and the recipient knows that
no one else read the message.
