Edit the cipher list

To edit the cipher list, perform the following steps:

  1. Enter the appropriate cipher in the text box.


    • The default cipher list is PCI compliant. To edit the cipher list to improve the security level on your server, read Apache's SSLCipherSuite Directive documentation.
    • We do not recommend that you edit the cipher list to lower the security level. Make certain that the cipher suite uses at least 128-bit encryption.
  2. Click Save.


    For your updated cipher list to take effect, you must enable the SSL Support for cPanel daemons (no stunnel) option in the System section of WHM's Tweak Settings interface (Home >> Server Configuration >> Tweak Settings).
