For cPanel & WHM version 66

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

Overview

The system uses cipher suites to negotiate security settings for Web Disk network connections over TLS/SSL. This interface allows you to edit the TLS/SSL cipher list for Web Disk.

Important:

We recommend that only advanced users edit the cipher list.

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

ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA:ECDHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-RSA-AES256-SHA256:DHE-RSA-AES256-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA256:AES256-SHA256:AES128-SHA:AES256-SHA:!DSS

Edit the cipher list

To edit the TLS/SSL Cipher List value, perform the following steps:

  1. Enter the appropriate cipher in the text box.

    Notes:

    • 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.
