Wtls Minimum Strong Ecc Key Length It Policy Rule - Blackberry Infinity B1367WD User Manual

Policy Reference Guide
This rule specifies the minimum DH key size (in bits) to use over WTLS connections. The permitted range is 512 through 4096 bits.
Default value
The default value on a BlackBerry® device is 1024 bits.
The default value on the BlackBerry® Enterprise Server is 512 bits.
Usage
If you configure the minimum key size on the BlackBerry Enterprise Server to be higher than the minimum key size on a BlackBerry
device, the BlackBerry device continues to prompt the user to trust every secure web site that uses a key size in its certificate
that is lower than the minimum key size on the BlackBerry Enterprise Server.
For example, when a user browses to a secure web site that uses a 512-bit DH key in its certificate, the BlackBerry device prompts
the user to trust the web site. If the user trusts the web site and selects the Don't Ask Again option, the minimum key size on the
BlackBerry device is configured to 512 bits. If you configure the minimum key size on the BlackBerry Enterprise Server to 2048
bits, the BlackBerry device continues to prompt the user to trust every secure web site that uses a key size in its certificate that
is lower than 2048 bits.
This rule is obsolete in BlackBerry Enterprise Server version 5.0 SP2.
Minimum requirements
• Java® based BlackBerry device
• BlackBerry® Application Suite version 1.0
• BlackBerry® Connect™ version 4.0
