# NOTE: 2 of 3 rule(s) below carry no published certificate and alert on

# rev:2 — alert tcp on address and port; alert tls with tls.cert_fingerprint only where the full
#   certificate SHA-256 is published. REPLACE any rev:1 file (every rule was alert tls) rather than
#   loading it beside this one: a same-sid different-text pair is a duplicate Suricata refuses.
