Description

When loading rules, check if the associated Suricata application has the ability to use ja3 (check for HAVE_NSS), and then check if ja3 is enabled.

If it is determined that the Suricata instance does not have ja3 enabled, emit a warning and automatically disable ja3 rules.

2 things I wanted to mention:

  1. we added a new notation
  2. we had 3 more keywords that depend on ja3 support
$ ./src/suricata --list-keywords|grep ja3
- ja3.hash
- ja3.string
- ja3s.hash
- ja3s.string
