# NOTE: 2 of 3 rule(s) below carry no published certificate and alert on
# address and port (alert tcp); the rest match the certificate fingerprint in the TLS handshake (alert tls).

# scope: host 193.37.69.43
# 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.
