Key Length IT policy rule

Description

This rule specifies the key size (in bits) that a BlackBerry® device generates.  The permitted range is 512 through 16,384 bits.

Default value

The default value is 1024 bits.

Usage

If you change the Key Algorithm rule to RSA®, you must configure the key size to be a multiple of 64.

If you change the Key Algorithm rule to DSA, you must configure the key size to be 512,768, or 1024 bits.

If you configure an unsupported key size, a BlackBerry device chooses the next strongest key size and generates the key.

Minimum requirements

  • Java® based BlackBerry device
  • BlackBerry® Device Software version 5.0
  • BlackBerry® Enterprise Server version 5.0
