Was looking into Certificate Transparency logs recently. Are there any convenient tools/methods for querying CT logs? i.e. search for domains within a timeframe

Cloudflare’s Merkle Town[0] is useful for getting overviews, but I haven’t found an easy way to query CT logs. ct-woodpecker[1] seems promising, too

Steampipe have a fun SQLite extension that lets you query them via SQL: https://til.simonwillison.net/sqlite/steampipe#user-content-...

It uses an API provided by https://crt.sh/

Querying crt.sh helped me identify a dev service I was supposed to take down, but forgot about it. Nice alternative use case :D
