sysconf tls ciphers set

Set the list of ciphers that the Network HSM appliance's TLS service uses to negotiate connection security for a session.

NOTE This feature requires minimum appliance software version 7.2 and client 7.2. See Version Dependencies by Feature for more information.

You can change the list of TLS ciphers by listing them in the LunaSH command line in the order of desired priority (-list), or by creating a file containing this list and transferring it to the appliance admin files (-applytemplate). The following rules apply to both methods:

>You can use valid OpenSSL arguments to simplify your specifications, such as:

•kECDHE (cipher suites using ephemeral ECDH key agreement, in default order)

•kDHE (cipher suites using ephemeral DH key agreement, in default order)

•kRSA (cipher suites using RSA key exchange, in default order)

•ALL (all not-otherwise-specified ciphers, in default order)

>Ciphers or arguments in the list must be separated by colons (:). For example:

ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ALL

>The list/template can contain a maximum of 255 characters, including colon separators. To avoid reaching this character limit:

•Specify only the ciphers you intend to use. It is not necessary to include the entire list.

•If you do wish to include the entire list, specify the most important ciphers first, and then use the ALL option to complete the list in the default remaining order.

Syntax

sysconf tls ciphers set {-list <cipher_list> | -applytemplate <file name>} [-force]

Argument(s)	Shortcut	Description
-applytemplate <file name>	-a	File name of a template file to apply. Either a template file with -applytemplate, or a command line list with -list must be applied.
-list <cipher list>	-l	Colon-separated list of ciphers to apply. Either a template file with -applytemplate, or a command line list with -list must be applied.
-force	-f	Force the action without prompting.

Description

-applytemplate <file name>

-a

File name of a template file to apply.

Either a template file with -applytemplate, or a command line list with -list must be applied.

-list <cipher list>

-l

Colon-separated list of ciphers to apply.

Either a template file with -applytemplate, or a command line list with -list must be applied.

-force

-f

Force the action without prompting.

Example using a template file

This operation will set the TLS cipher suites to use the following cipher suites:
Cipher suites are listed from highest to lowest priority.
