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 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.
