create a drop-down for "SSL ciphers" in the "APPLICATION SETTINGS" below the "TLS VERSIONS" for customers who want only strong SSL ciphers
Customers can get an A+ rating on https://www.ssllabs.com/ssltest/ if you:
Add an "SSL ciphers" drop-down for customers that are interested in only using strong SSL ciphers.
You can consider your current ciphers as "default", and add an option for "most secure" that allows customers to select a pre-defined "A+ rated" SSL cipher configuration.
The "SSL Cipher" configuration would go below the existing "TLS VERSIONS" option in the "APPLICATION SETTINGS" > "GENERAL" > "TLS VERSIONS" configuration interface.
