Securing your email
You can digitally sign or encrypt messages if you use a work email account that supports S/MIME-protected messages 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. 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. 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.
- PEM (.pem, .cer)
- DER (.der, .cer)
- PFX (.pfx, .p12)
