# Configuration of Cipher Suites

If desired, you can specify the cipher suites to be used when the Central Administration server uses SSL to connect to EMS servers or accepts web browsers connections with the HTTPS protocol.

To configure this feature, you can either provide a cipher suite specification with the `--ssl-ciphers` command line option when the Central Administration server is started, or set a configuration parameter in the Central Administration configuration file. Both methods accept the Java Client Syntax described in the TIBCO Enterprise Message Service User’s Guide. This is further documented in Central Administration Server Options.
