TLS Version Support for Filecloud

Original Question or Issue:

Looking at filecloud version 21.2.1.17295
It appears that it only supports TLS v1.2 is supported

*** Are we able to run version TLS v1.3 on the webservers?

Environment:

  • Product - Filecloud Server
  • Version - Any
  • Platform - Linux

Steps to Reproduce:

 

Error or Log Message:

 

Defect or Enhancement Number:

 

Cause:

Customer is running on Rhel 7.9 for their SVP and Production Environment.

Resolution or Workaround:

RHEL 7.9 ships with OpenSSL 1.0.2k, which does not support TLS 1.3. TLS 1.3 support was introduced with OpenSSL 1.1.1, which is only available natively starting from RHEL 8.

Given this, the error you're encountering — SSLProtocol: Illegal protocol 'TLSv1.3' — is expected behavior on this platform.

As referenced in Red Hat's official KB article:

  • The latest version available of openssl for RHEL 7 is 1.0.2k-fips, which has no support for TLSv1.3.

  • There is currently no plan to implement TLSv1.3 support for RHEL 7 and earlier versions.

  • Red Hat recommends to upgrade to RHEL 8 for TLSv1.3 support.
