Securing your email
You can digitally sign or encrypt messages if you use a work email account that supports S/MIME or PGP protected
messages or IBM Notes email encryption on your BlackBerry device. Digitally signing or encrypting messages adds another
level of security to email messages that you send from your device.
Digital signatures are designed to help recipients verify the authenticity and integrity of messages that you send. With S/
MIME-protected messages, 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 hasn't been changed.
Encryption is designed to keep messages confidential. With S/MIME-protected messages, 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.
Even if your email account isn't supported by an EMM solution from BlackBerry, if it's supported by Microsoft Exchange
ActiveSync and your organization uses an LDAP directory, you can encrypt your messages using S/MIME.
If you use a work account that supports PGP protected messages, you can digitally sign, encrypt, or sign and encrypt
messages using PGP protection. You need to store the recipient's public key on your BlackBerry device to send encrypted
email messages. You need to store your private key on your device to send digitally signed email messages.
