This document is for a previous release of cPanel & WHM. To view our latest documentation, visit our Home page.

For cPanel & WHM 11.44

(Home >> Service Configuration >> cPanel Web Services Configuration)

Overview

This interface allows you to configure or edit the TLS/SSL Cipher List for cPanel, WHM, and Webmail.

The system uses cipher suites to negotiate security settings for a network connection over TLS/SSL.

Important:

We recommend that only advanced users edit the cipher list.

 

By default, WHM uses the following cipher list for web services:

ALL:!ADH:+HIGH:+MEDIUM:-LOW:-SSLv2:-EXP

Edit the cipher list

If you wish to edit the cipher list, perform the following steps:

  1. Enter the appropriate cipher in the text box.

    Note:

    • The default cipher list is PCI compliant. If you wish to edit the cipher list to improve the security level on your server, read the documentation for SSLCipherSuite Directive at Apache.org.
    • 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.

    Important:

    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).
