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 and protocol lists for Web Disk.

Warning:

We recommend that only advanced users edit the cipher and protocol lists.

Important:

cPanel & WHM supports Transport Layer Security (TLS) protocol version 1.2 and Transport Layer Security (TLS) protocol version 1.3:

  • cPanel & WHM only supports TLSv1.2 or newer. The system enables TLSv1.2 by default.
  • Not all clients will support TLSv1.3, which requires OpenSSL 1.1.1 or higher.

Defaults

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

ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256

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

SSLv23:!SSLv2:!SSLv3:!TLSv1:!TLSv1_1

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.
    Note:
    • 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.

Edit the protocol list

To edit the TLS/SSL Protocol list, perform the following steps:

  1. Enter the appropriate protocols in the text box.
  2. Click Save.
