S/MIME Allowed Content Ciphers IT policy rule


This rule specifies the encryption algorithms that a BlackBerry® device can use to encrypt S/MIME-protected messages.

Default value

The default value is to use all supported algorithms.


To maintain compatibility with most S/MIME clients, use Triple DES encryption and one of the RC2 algorithms. By default, a BlackBerry device is designed to encrypt email messages using Triple DES encryption if it does not know the decryption capabilities available to the recipient.


If you configure the FIPS Level IT policy rule to 2, a BlackBerry device uses AES (256-bit), AES (192-bit), AES (128-bit), and Triple DES encryption.

Minimum requirements

  • Java® based BlackBerry device
  • S/MIME Support Package for BlackBerry® smartphones version 1.5
  • BlackBerry® Application Suite version 1.0
  • BlackBerry® Connect™ version 4.0
  • BlackBerry® Device Software version 3.6
  • BlackBerry® Enterprise Server version 4.0 SP3


The BlackBerry® Enterprise Server for Novell® GroupWise® does not support this rule.
