Use only these ciphers

Use the ciphersuites parameter to restrict the set of cipher suites that can be used with the SSL protocol.

ciphersuites=<name>
Description
Specify the cipher suites that CICS® Transaction Gateway client applications can use to connect to CICS Transaction Server for z/OS®. You can define multiple cipher suites by separating them with a comma. If none of the cipher suites listed are supported by the JSSE provider, CICS Transaction Gateway fails to start. If no cipher suite is specified or the parameter is omitted, all available cipher suites can be used.

This parameter is in the IPICSERVER section of the configuration file.

Default value
If this parameter is not specified, the default is that all available cipher suites are available.
Configuration Tool
In the Configuration Tool, you can set the value of ciphersuites in the Use only these ciphers field in the Server connection page page. This page can be accessed by selecting an existing server in the CICS Servers section of the CICS Transaction Gateway pane or by creating a server definition. To create a server definition, click Options > New Serveror click the New Server icon.

Enter the cipher suite name in the field, and then click Add to add it to the list. To remove a cipher suite, select the suite in the list and click Remove.
