S/MIME Allowed Content Ciphers IT policy rule

Description

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

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