The ciphers attribute can carry a comma-separated list of encryption ciphers that this socket is allowed to use. By default,
the web UI uses the default ciphers for the Java Virtual Machine (JVM). These contain the weak export-grade ciphers
in the list of available ciphers. This results in the web UI supporting weak cipher session keys.

The ciphers are specified using the Java Secure Socket Extension (JSSE) cipher naming convention.

Step 3

Restart Cisco Prime Network Registrar for the changes to take effect.
