My proposal is to set the ciphers to a strong set. This may break older clients, but those platforms are typically EOL.

Revision 68cf3241 (diff)
Added by Ewoud Kohl van Wijngaarden over 2 years ago

Fixes #31385 - Default to strict qpid-router

Prior to this weak and insecure ciphers were used. While this change
only mentions ciphers, in practice it looked like it also disabled TLS
1.0 and 1.1

Before:

Revision 8610c990 (diff)
Added by Ewoud Kohl van Wijngaarden over 2 years ago

Refs #31385 - Clear out nil qpid ciphers

The parameter qpid_router_ssl_ciphers no longer accepts undef (nil) but
now always sets the ciphers. This migration clears out the invalid value
which will later copy the module default.
