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.

Your BlackBerry device supports keys and certificates in the following file formats and file name extensions:

•PEM (.pem, .cer)

•DER (.der, .cer)

•PFX (.pfx, .p12)
