Configuring Jetty SSL Ciphers
The SSL Ciphers that Jetty is allowed to use is defined in installation.properties located in the {RHYTHMYX_HOME}\jetty\base\etc directory.
By default we restrict the ciphers we use to a modern level. However any cipher from the intermediate group can be added to the perc.ssl.includeCiphers entry in installation.properties for Rhythmyx to use.
Modern Ciphers
If you want the least amount of security vulnerabilities, then Percussion recommends using only the modern ciphers and only using the TLSv1.2 protocol.

These ciphers protect against the following vulnerabilities and attacks:

Intermediate Ciphers
These ciphers are all available ciphers that can be enabled in Rhythmyx. If you find that the modern ciphers do not cover the browser you wish to support, then you can enable the below ciphers as well as the protocols TLSv1.1 and TLSv1.

All SSL Ciphers
As of Rhythmyx Version 7.3.2, and the version of Java we ship with: 1.8.0_66, allows the following list of ciphers to be used. This list includes insecure ciphers, the intermediate and modern lists are obtained through this list, but are shortened so that the least secure ciphers are not usable by Rhythmyx.
