How do I process encrypted mail on a BlackBerry device?

Sending IBM Domino encrypted and signed mail messages can be performed from a BlackBerry 10 device activated on a BlackBerry Enterprise Server 10.0 or higher.

This functionality is implemented using an encryption and decryption strategy that requires server-side access to the user's Notes ID file. The ID file contains the private and public keys necessary to digitally sign, encrypt, and decrypt mail messages. Receiving and reading encrypted mail can be performed on a BlackBerry 10 device without being activated on a BlackBerry Enterprise Server.

For digital signing, encrypting, or decrypting to work, the Notes ID file must be uploaded to the mail file or a Domino ID vault. For more information, see "How do I upload my Notes ID file?" in this topic.

The minimum requirements for processing (sending or viewing) encrypted mail on a BlackBerry device are as follows:
  • IBM Traveler Server IF1 or higher
  • BlackBerry 10 device with OS version 10.2 or higher
  • User's Notes ID must be accessible to the IBM Traveler Server
  • BlackBerry 10 device must be activated on a BlackBerry Enterprise Server (BES) 10.0 or higher for sending encrypted messages
Note: Reading or viewing Domino Encrypted mail on a BlackBerry 10.2 (or higher) device does not require the device to be activated using a BES server.
Note: Only Domino-encrypted mail is supported. Encrypted calendar, to-do, and notebook entries are not supported. SMIME encryption is unavailable.
Note: Use either a secure socket layer (SSL) connection or a virtual private network (VPN) solution when encryption is enabled on the IBM Traveler server.
Note: Domino encrypted mail is referred to as Notes Native Encryption (NNE) on a BlackBerry 10 device.
