description: "crt.sh by Sectigo — searches the public Certificate Transparency logs, where every publicly trusted TLS certificate is recorded. Lists a domain's sub-domains and who issued their certificates, shows when a host first got a certificate (a phishing site usually gets one the day it goes live), and finds look-alike domains that start with a client's brand. Free, no API key; stdlib-only. crt.sh is a shared public service: it is slow on big domains and a starts_with search on a short word can time out — keep searches narrow. As a context enrichment rule (Riposte 0.299+, no score field) on domains: search_certificates with summary `${name_count} names, newest certificate ${certificates.0.not_before}`."
