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.

About encryption icons

When you open an encrypted message, a lock icon represents the encryption status. Your system administrator sets an IT Policy that determines whether the encryption algorithm that the message uses is considered to be strong or weak.

Lock: The message is strongly encrypted.

Lock with a question mark: The message is weakly encrypted.
