About signing and encrypting messages
If your email account uses a BlackBerry® Enterprise Server that supports this feature, 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.

You can sign or encrypt email messages and PIN messages.

Encrypt a message with a pass phrase
Your BlackBerry® device can encrypt email messages and PIN messages using a pass phrase shared between the sender and recipient.
1. In an unsent message, set the Encoding field to Encrypt or Sign and Encrypt.
2. Press the Menu key.
